Photocurable bulk epoxy resins based on resorcinol derivative through cationic polymerization

AbstractBio‐sourced epoxy resins from resorcinol diglycidyl ether (RDGE) have been obtained by using cationic photopolymerization under UV‐light exposure. The photoinduced bulk resin samples were characterized by three‐point bending tests, dynamic mechanical analysis, as well as differential scanning calorimetry analysis, and thermogravimetric analysis. The influence of processing parameters, that is, reactant contents, UV irradiation time, and postcuring conditions on the thermomechanical behavior has been pointed out. For instance, the flexural modulus of the most performing materials reaches 4.1 GPa with the flexural strength and the glass‐transition temperature of around 105 MPa and 99°C, respectively. Interestingly, our optimized protocol has led to the synthesis of new bio‐based materials with more valuable thermal and mechanical properties than those of thermocured materials obtained from petroleum‐based commercial epoxy resins. Focus has been given on processing parameters to optimize the final properties of the material and to open an interesting alternative for sustainable building materials.

Laboratory evaluation on water-based and flexible epoxy/SiO2 nanocomposites to enhance anti-sliding effectiveness of pavement

The anti-slip (AS) layer of the cement concrete pavement (CCP) can probability decrease traffic accidents and extend the service life of the road. Epoxy resin has excellent adhesion and mechanical strength, making it possible in this field. Herein, a flexible waterborne epoxy resin (WER) without a small molecule emulsifier was synthesized by bisphenol A epoxy resin, poly (propylene glycol) diglycidyl ether (PDE), diethylenetriamine (DETA). The mechanism of the group reaction was characterized by fourier transform infrared (FTIR), and dynamic scanning calorimetry (DSC) determined the heat of curing of WER. Then, the physical properties of WER were enhanced by the silane coupling agent modified nano-silica (SCA-NS) and the composite’s water absorption rate and mechanical propriety were evaluated. Finally, the pavement performance of the AS layer was prepared and tested as well as compared with the commercial waterborne epoxy resin (CWER) and emulsified asphalt (EA). The result shows EA has low durability and adhesion strength than epoxy resin. The small molecule emulsifier and low-flexible resistance of CWER decrease water stability and anti-sliding durability of the AS layer. Due to applied nanomaterial reinforced and without small molecule emulsifiers, the WER base AS layer shows extremely high adhesion strength, water stability, and skid-resistance durability at addition 3 wt% of SCA-NS, which have a great potential for CCP.

Effect of Boron Nitride Nanosheets on Properties of a Commercial Epoxy Molding Compound Used in Fan-Out Wafer-Level Packaging

In this article, the effect of incorporating boron nitride nanosheets (represented as BNNSs in this article) in a commercial epoxy molding compound (EMC) that has been used in the fan-out wafer-level packaging (FOWLP) is investigated. The BNNSs were produced by exfoliating hexagonal boron nitride (h-BN) in water and were incorporated in EMC without any surface modification. BNNS-reinforced EMCs were prepared by adding various concentrations of BNNSs in the pristine EMC, followed by thermal curing. The characterization of nanocomposite samples implies that the epoxy-hardener reaction is not significantly affected by the presence of BNNSs. Surprisingly, EMCs containing low concentrations of BNNSs showed better thermal stability and thermomechanical properties when compared to the pristine EMC. Meanwhile, a sample with the highest concentration of BNNSs performed poorly, which could be due to the BNNS agglomeration and filler/polymer phase separation. This method is a simple and inexpensive way to alter the mechanical properties of commercial EMCs. The tunability of material properties is foreseen to broaden the materials of choice for FOWLP, support product customization, and tackle the warpage issue in FOWLP from the material engineering perspective.

Thermo-Mechanical and Wear Behaviour of Surface-Treated Pineapple Woven Fibre and Nano-Silica Dispersed Mahua Oil Toughened Epoxy Composite

In this present investigation effect of adding surface treated pineapple and nano-silica into mahua seed oil (Madhuca longifolia) toughened epoxy bio composite material was studied. The prime objective of this present investigation was to produce high toughness commercial epoxy bio composite with natural blender, fibre and filler. The bio blender (mahua) of density 0.9 g/cm3 with 10 and 15 vol.%, pineapple natural fibre of density 1.4 g/cm3 with 30 vol.% and nano-silica particle of 20 nm with 0.5 and 1.0 vol.% were used as reinforcements. The pineapple fibre and nano-silica particles were surface treated using APTES (3-Aminopropyltriethoxysilane) via aqueous solution method. Composites were made using hand lay-up method and evaluated for mechanical, thermal and wear in accordance with ASTM standards. The mechanical results showed that adding 30 vol.% of surface-treated pineapple fibre with 1.0 vol.% of nano-silica particle in mahua oil of 15 vol.%-epoxy bio blend gives maximum tensile, flexural and impact strength of 160 MPa, 225 MPa and 5.5 J. The TGA (Thermogravimetry analysis) and wear results explicated that adding 1.0 vol.% of nano-silica into mahua (15 vol.%)-epoxy bio blend offers highest stability and wear resistance. The SEM (Scanning electron microscopy) morphological images revealed reacted phase of pineapple fibre and nano-silica with mahua-epoxy blend. The fractograph images show striations on the failure direction, which revealed improved toughness of epoxy resin blend. These mechanically and thermally strengthened bio-composites could be used in structural, automobile and domestic applications.

Synthesis and characterization of TiO2/acrylic acid-co-2-acrylamido-2-methyl propane sulfonic acid nanogel composite and investigation its self-healing performance in the epoxy coatings

In the present study, the surface of titanium dioxide (TiO2) nanoparticles was modified with superabsorbent gel based on acrylic acid (AA) and 2-acrylamido-2-methyl propane sulfonic acid (AMPS) via in-situ polymerization using 3-(triethoxysilyl) propyl methacrylate (MPS) as a silane coupling agent. The synthesized TiO2 nanogel composite was then incorporated into a commercial epoxy resin in different weight percent (1, 2, and 4) to prepare an effective self-healing epoxy coating. The chemical structure and surface morphology of the prepared nanogel composite were evaluated by Fourier transform infrared (FTIR), X-ray diffraction (XRD), and Field Emission Scanning Electron Microscopy (FESEM). Furthermore, to calculate the weight ratio of the inorganic to organic materials, the ash content test was employed. The effectiveness of the TiO2 nanogel composite as the self-healing material in the epoxy resin was assessed in 3.5 wt.% NaCl solution by potentiodynamic polarization tests and electrochemical impedance spectroscopy (EIS).

Phenolic fatty acid-based epoxy curing agent for antimicrobial epoxy polymers

Epoxy resins are one class of important reactive pre-polymers used in the coating industry. To manufacture epoxy resins with antimicrobial properties, active quaternary ammonium groups are often introduced into the polymeric backbones following resin polymerization reactions for structure modification. However, these complicated approaches associated with these types of reactions make the commercialization of the antimicrobial epoxy polymers uneconomical, impractical and inconvenient. Besides, quaternary ammonium groups are undesirable because the hydrophilicity of the groups makes the resins less water-resistant. In order to simplify the development of antimicrobial epoxy polymers, we prepared an amide by reacting novel bio-based phenolic-branched fatty acids with ethylenediamine. The resulting amide was cured into a commercial epoxy resin -- diglycidyl ether of bisphenol A (DGEBA), which was solution-cast into epoxy polymer films. The antimicrobial activities of the resulting epoxy polymer films were investigated. The crude phenolic branched fatty acid amides (PBC-FAAs) as curing agents were separated and characterized by thin-layer chromatography, proton nuclear magnetic resonance (1H-NMR), gas chromatography-mass spectrometry (GCMS), liquid chromatography-mass spectrometry (LC/MS) and Fourier-transform infrared spectroscopy (FT-IR). The thermal and mechanical properties of the polymer films were also investigated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and dynamic mechanical analysis (DMA). Cured epoxy films prepared from purified PBC-FAA exhibited antimicrobial activity against Listeria innocua. However, the crude, unpurified PBC-FAA-cured epoxy film showed much more promising antimicrobial activity against both Listeria innocua (Gram positive) and Escherichia coli (Gram negative).

Sol–gel based layer-by-layer deposits of lanthanum cerium molybdate nanocontainers and their anticorrosive attributes

The present study focuses on the synthesis of novel lanthanum cerium molybdate (LCM) nanoparticles by sol–gel synthesis method and their use in the development of nanocontainers in an anticorrosive coating application. The obtained nanoparticles were used as core material with two different polyelectrolytic shells comprising of polypyrrole (PPY) and polyacrylic acid (PAA) or polyethyleneimine (PEI) and polystyrene sulfonate (PSS) involving the entrapment of benzotriazole (BTA) as the corrosion inhibitor using layer-by-layer (LBL) deposition method. At each step of this nanocontainer synthesis, the thickness of the layers, surface charges and the presence of the functional groups were determined by particle size, zeta potential and Fourier transform infrared spectroscopy (FTIR) analysis, respectively. The X-ray diffractograms (XRD) indicated the change in the crystallinity of the nanoparticles and nanocontainers while thermogravimetric analysis (TGA) showed the thermal degradation behavior of the nanocontainers. The morphological studies conducted using scanning electron microscopy (SEM) exhibited the formation of nanocontainers containing nanoparticles in their cores. The release of BTA from the nanocontainers was evaluated at different pH values. The anticorrosive performance of the nanocontainers was examined by incorporation of the nanoparticles and nanocontainers in a commercial epoxy coating system and to be applied on mild steel and magnesium panels by electrochemical corrosion analysis. Tafel plots demonstrated the decrease in the current density with an increase in the loading percentage of nanocontainers in the epoxy system while Bode plots confirmed the significant improvement in the corrosion protection of the mild steel and magnesium by LCM nanoparticles and nanocontainers.

Utilization of Lignin-Derived Small Molecules: Epoxy Polymers from Lignin Oxidation Products.

Much effort has been invested in developing methods for producing small molecules from lignin as a way to source feedstock chemicals from renewable sources. Significant progress is being made, and methods for deconstructing lignin are producing good yields of small, mononuclear aromatic products-sufficient amounts to enable studies of the potential use of these compounds as replacements for compounds currently produced from petroleum. To investigate the use of lignin products in epoxies, we begin with aromatic acids that can be produced from lignin, treat them with epichlorohydrin to make glycidyl ethers, and investigate the thermal and mechanical properties of cured mixtures of these compounds with a commercial epoxy resin (EPON 826) and an anhydride curing agent (NMA). While most of the lignin-modified epoxy polymers exhibit good physical and thermal properties, the polymer prepared from p-hydroxybenzoic acid (compound 6) has a higher glass-transition temperature (Tg = 159 °C) than do thermosets made with other lignin-derived materials, such as vanillic acid diglycidyl ether (compound 4) and matches the Tg of cured samples of the commercial EPON-826/NMA epoxy system. This is significant, as p-hydroxybenzoic acid is readily available by simple hydrolysis of several different lignins and functions as a drop-in replacement for 50% of the BPA-based material in this commercial system without significant degradation of material properties. The use of lignin-derived small molecules in high-value systems such as epoxies may help improve the economics of biorefineries.

Sustainable alternative to bisphenol A epoxy resin: high-performance recyclable epoxy vitrimers derived from protocatechuic acid

A series of epoxy vitrimers were prepared based on protocatechuic acid, which showed better thermal and mechanical properties than commercial BPA-based epoxy resins. The vitrimers can be reprocessed in high efficiency and degraded in NaOH solution.

Potentiality of Epoxy-Montmorillonite Composite for Stir-Bar Sorptive Extraction for Determination of Atrazine

Abstract A new low-cost material is presented for the first time, aiming to study the sorption process for the stir-bar sorptive extraction (SBSE) technique. The bars were made using a composition of a commercial epoxy resin and montmorillonite, under different compositions and a final ratio of 70% (epoxy) and 30% (montmorillonite) was employed, providing the best mechanical and chemical resistance. A PTFE support was developed to hold the bars permitting the magnetic stirring, without turbulent behavior even under long times of stirring at 1000 rpm. The bars were employed to study the sorption of the herbicide atrazine (ATZ), and the best extraction conditions were: sample volume 20.0 mL, pH 6.0, extraction time of 15 min, room temperature, stirring speed of 100 rpm, and 10.0% (w v-1) NaCl. This preliminary evaluation suggests that the modified bars could be employed for ATZ sorption, affording close to 71% of ATZ removal, and presented robust characteristics to be used at least 80 times.

Multi-Point Covalent Immobilization of Enzymes on Supports Activated with Epoxy Groups: Stabilization of Industrial Enzymes.

Commercial epoxy supports may be very useful tools to stabilize proteins via multipoint covalent attachment if the immobilization is properly designed. In this chapter, a protocol to take full advantage of the support's possibilities is described. The basics of the protocol are as follows: (1) the enzymes are hydrophobically adsorbed on the supports at high ionic strength. (2) There is an "intermolecular" covalent reaction between the adsorbed protein and the supports. (3) The immobilized protein is incubated at alkaline pH to increase the multipoint covalent attachment, thereby stabilizing the enzyme. (4) The hydrophobic surface of the support is hydrophylized by reaction of the remaining groups with amino acids in order to reduce the unfavorable enzyme-support hydrophobic interactions. This strategy has produced a significant increase in the stability of penicillin G acylase compared with the stability achieved using conventional protocols.

Polyamine-modified reduced graphene oxide: A new and cost-effective adsorbent for efficient removal of mercury in waters

This paper describes the synthesis and characterization of polyamine modified reduced graphene oxide rich with mixed amino groups as a cost- and performance- efficient adsorbent for mercury removal from waters. The synthetic approach is based on a simple process to functionalize graphene oxide (GO) with low-cost commercial polyamine epoxy hardener followed by the reduction of created polyamine-GO hybrid by hydrothermal (HT) or chemical reduction (CM) process with hydrazine. Both polyamine modified reduced graphene oxide (rGO), referred as HT-rGO-N and CM-rGO-N, exhibited 8.28% and 5.47% N content, respectively. Mercury adsorption study showed that these rGO functionalized composites have high adsorption kinetics, reaching equilibrium within the first ten minutes. The adsorption kinetics and equilibrium of their adsorption process can be well described using pseudo-second order and Freundlich isotherm models with estimated sorption capacity of 63.8 mg/g and 59.9 mg/g for HT-rGO-N and CM-rGO-N respectively. The adsorption capacity for Hg is achieved in broad range of pH (pH 5–9) and can be described as high-performing compared with other amino based adsorbents reported in the literature. More importantly, these adsorbents showed very high selectivity towards Hg(II), outperformed the commercial activated carbon adsorbent with only ~16% mercury removal efficiency achieved in multimetallic solution consisting of Hg(II), Cd(II), Co(II), Cu(II) and Pb(II) ions in both solid and dispersed forms. Finally, these polyamine functionalized rGO adsorbents confirmed their notable performance in regeneration and removal of spiked mercury from natural waters mimicking real applications. These results demonstrated realistic water remediation capabilities of developed polyamine functionalized rGO adsorbents as promising candidates for environmental applications.

High performance epoxy nanocomposites with enhanced thermal and mechanical properties by incorporating amine-terminated oligoimide-grafted graphene oxide

In this work, thermal conductivity and mechanical strength of a commercial epoxy resin were improved by incorporating an amine-terminated oligoimide modified graphene oxide (ATO-GO). For this purpose, the surface of GO was modified with flexible/stable imide backbone and amine terminals. The ATO-GO was incorporated in epoxy proportion to prepare series of nanocomposites. The terminal amino group of ATO-GO also acted as curing moiety for epoxy resin leading to good interfacial compatibility and dispersion in the epoxy matrix resulting in improved properties. The epoxy resin was cured with hardener Aradur-22962 and ATO-GO separately and the results of curing behavior were compared with each other, which clearly showed the curing action of ATO-GO. In the prepared ATO-GO-epoxy nanocomposites, the filler enhanced the thermal conductivity, hardness and elastic modulus without decrease in thermal stability even at higher filler loading. In previous studies, it is reported that at higher GO, filler-loading properties like elastic modulus, hardness values, and glass transition temperature ( T g) were decreased. An enhancement of 59.5% in thermal conductivity was achieved for 5 wt% loading of ATO-GO filler as compared to neat epoxy. Along with this, thermal analysis revealed that the nanocomposites with 5 wt% filler loading have high T g and thermal strength. Nanoindentation results revealed that elastic modulus and hardness values enhanced by 104% and 147%, respectively, for the same nanocomposites. The enhanced thermal conductivity and good elastic behavior of the ATO-GO-epoxy nanocomposites demonstrated that these can be used as high-performance materials in electronic packing and electronic devices.

Epoxy Self-Healing Coating by Encapsulated Epoxy Ester Resin in Poly (Urea-Formaldehyde-Melamine) Microcapsules

In this work, poly (urea-formaldehyde-melamine) (PUFM) microcapsules containing a commercial epoxy ester resin were synthetized by in-situ polymerization technique. The microcapsules size distribution was analyzed by laser diffraction and the obtained microcapsules were evaluated by the Fourier-transform infrared spectroscopy (FTIR), in order to prove the ester epoxy resin microencapsulation. The filled microcapsules were incorporated in an epoxy three layer coating system, varying the microcapsules concentration (10 % and 15 %) and the microcapsules incorporation on the different layers - first, second or both. The coatings electrochemical behaviors were evaluated by electrochemical impedance spectroscopy (EIS) technique and localized scanning vibrating electrode technique (SVET). Pull-off adhesion tests were performed in the coatings systems, in order to verify if the microcapsules presence did affect the adhesion and/or cohesion coating properties. The EIS results showed that microcapsules change the coating electrochemical response, but the samples visual aspect suggests that the microcapsules improve the barrier properties of the microcapsules systems. The coating system containing the microcapsules showed a significant self-healing effect when stressed by a mechanical defect and the higher concentration (15 wt. %) of microcapsules provided a better self-healing protection, with better anticorrosive performance. Additionally, the microcapsules did not disturb the adhesion/cohesion properties of the coating system.

Improvement and Properties of Fiber Metal Laminates Used in Aircraft Wing by Using Graphite-Polyester

The main objective of this study is to reduce weight and to improve the mechanical properties of aircraft wing by using Hybrid materials known as fiber metal laminates (FMLs). They are new age of engineering materials, which consist of metal layers reinforced with fibers emerged by matrix phase. In this study, seven layers were used to produce the FMLs, which are consist of aluminum alloy2024-T3 reinforced by carbon and glass fibers bonded with using blend of graphite-polyester as adhesion. The Carbon Glass Reinforced Aluminum Laminates (CAGRALLs) is used as FMLs. The results show that the CAGRALLs give better in mechanical properties because of increasing in tensile strength, yield strength, , elastic modulus, elongation at fracture, flexural modulus and impact toughness except flexural strength by comparing with FMLs by using commercial epoxy as adhesion for other researchers. The increasing in layers is led to weaken adhesion force between layers of FMLs that led to decrease almost mechanical properties. The FMLs has good mechanial properties by using carbon and glass fiber by comparing with carbon and jute fibers. The CAGRALLs have the higher numbers of cycles at failure under cyclic loadings than Aramid Reinforced Aluminum Laminates (ARALLs). The CAGRALLs have the lower density by comparing with aluminum alloy 2024-T3 and steel that used in manufacturing of aircraft wing.

Nanotechnology to Improve the Performances of Hydrodynamic Surfaces

Nature continues to inspire scientists to adapt solutions in order to satisfy human needs, mainly in the maritime domain with metallic surface corrosion and its mechanical friction. In this research, the source of innovation comes from the lotus leaf and its well-known super-hydrophobicity. In this study, we have investigated the lotus leaf as a model for a super-hydrophobic maritime surface. The hydrothermal technique, which is considered to be a simple, low-cost, and scalable coating method, is applied to create zinc oxide (ZnO) nanorods (NRs), and an evaporation method is used to apply octadecyltrimethoxysilane (ODS). We apply such eco-green coatings onto commercial epoxy paints. Superhydrophobic surfaces (SHS) are obtained on maritime aluminum substrates. The characterization of SHS indicates improved behavior of water droplets on the treated surface: higher water static contact angles (WCA) from 98° to more than 152° and reduced sliding angles (SA) from 46° to 7°. Sliding speeds (SS) have been largely raised from 54 in the epoxy case to 1300 mm·s−1 after treatment. These results clearly demonstrate the real opportunity to apply ZnO-based nanomaterials onto existing commercial maritime coatings.

Rheological Properties of Epoxy/Polypyrrole Coating and its Behavior as EMI Material

In this study, we analyze the rheological properties of epoxy/polypyrrole/carbon black coating and its performance as electromagnetic interference shielding efficiency (EMI SE). For this purpose, a commercial epoxy coating was mixed with a conductive polymer, namely polypyrrole. Rheological tests were performed to obtain the flow curve, the storage and loss moduli, the cure time and thixotropic characteristics. Thermal analysis of DSC (cure behavior) and EMI SE were also performed. Epoxy coating showed non‐Newtonian (shear thinning) behavior. The addition of PPy.DBSA reduced the coating fluidity by the increase in consistency index and viscosity. The stress oscillatory amplitude sweep test was performed to determine the linear viscoelastic range. The results of the LVR stress and strain frequency sweep tests were compared to the PPy.DBSA. The results show that LVR and critical crossover change with the percent of Polypyrrole. The cure times obtained by the rheometer and DSC were in good agreement: the addition of polypyrrole reduced the cure time, probably due to the presence of amino groups in the PPy.DBSA, which can react with the oxirane ring in the epoxy resin. The EMI SE attenuation by absorption and reflection mechanism was observed by adding 10 phr of PPy.DBSA. For practical applications, it is necessary to combine polypyrrole with conducting carbon black. The formulation with 1.5 phr of carbon black improves the EMI SE performance to 72%. J. VINYL ADDIT.

Adhesive bonding of 3D-printed plastic components

ABSTRACTTensile strength of adhesive bonds with three different commercial epoxy resins and laser sintered polyamide 12 (PA 12) has been evaluated by means of Centrifugal Adhesion Testing Technology (CATT, LUMiFrac Adhesion Analyzer). Different post treatment states (as received and chemically smoothed) and pre-treatment states (as received and atmospheric plasma) of the PA 12 surface have been considered. It has been shown that the epoxy resins infiltrate the surface porosity of the laser sintered material, which leads to a special fracture pattern. Tensile strength of the adhesive bonds has been significantly improved after atmospheric plasma pretreatment. Chemical smoothing had a neglicable effect on the tensile strength of the tested specimens, but lead to a change in fracture pattern, especially without atmosphric plasma pretreatment.

Synthesis, identification and thermal study of some new inorganic polymers based on bis-dithiocarbamate ligands with silicone, tellurium and some transition metals

Introduction: In recent years, there has been considerable interest in dithiocarbamate complexes because of its diverse biological roles, very few reports have been made on polymeric bis- dithiocarbamate compounds with carbon chain of n-propyl or hexamethelene with transition metals in addition of the absence of any report of organosilicone or tellurium halides with such compounds Our interest in this report based on the preparation of new series of polymers with an expected activity as a fungi side compounds followed by the using of prepared amino compound as a hardners for epoxy paints Materials and Methods: A new polymers of the general structures –(MS2CNH(CH2)6NHCS2M-)n where [M= Cu, Cd, Mn and Zn] and –(M(R)2S2CNH(CH2)nNHCS2MR2-)m where [M= Si,R=CH 3 , n= 2 ,3 and 6 ; M=Te , R= Br , n= 2 ,3 and 6 ; M=Co, Ni R=Cl ; n= 6] have been prepared by reaction of MX2 where M= Ni ,Co, Cd , Mnor Zn , X= Cl ; M=Cu , X= SO4 , and dimethyl dichloro silane, tellurium tetrabromide with the corresponding sodium salts of bis-dithiocarbamateligands. Results and Discussion: Dimethyldichloro silane is a very sensitive material to O-H group, in addition to that, TeBr4 decomposed rapidlyin water so, a series solvents may be useful with such sensitive chemicals to water , in the other hand, dithiocarbamate ligands which is usually prepared in aqueous and alcoholic solution , must be prepared and isolated carefully to apply the other steps of synthesis using a chloroform solution as a solvent. It seems for the first view for dithiocarbamato ligands it may act as a bi dentate ligands using two sulphur donating atoms that is clearly appeared in common complexes such as diethyl dithiocarbamato or pipyridyl, morpholino dithiocarbamato with representation metal elements, even in such type of elements a sulfur bridges may formed. In this study, it showed clearly that Zinc and Cadimium polymers are diamagnetic polymers that is mean that these polymers are with oxidation state equal to (II) and a tetrahedral configuration Conclusions: The study showed that the new silicone polymers act as a stable polymers compared with others. All new polymers are of a high stability with large values of char contain with commercial epoxy. Among silicone polymers, the polymerwith carbon chain equal to 3 is more stable than that with 2 carbon atoms while the silicone polymer with 6 carbon atoms is the less stable one, may thermal treatment caused decomposition combined.
