Ultrasonic Velocity of Acrylates with Decane-2-ol at 313.15 K

Thermodynamic data involving ultrasonic velocities of binary liquid mixtures of methyl acrylate, ethyl acrylate and butyl acrylate with decane-2-ol have been measured at 313.15 K and at atmospheric pressure. Study of thermodynamic properties involves challenges of interpreting the excess quantities as a means of understanding the nature of intermolecular interactions among the mixed components. Experimental values of ultrasonic velocities were correlated with recently proposed Jouyban-Acree model. Deviations in isentropic compressibility were calculated and have been fitted to Redlich-Kister polynomial equation. Excess parameters like specific acoustic impendence, intermolecular free length, available volume, intrinsic pressure, molecular association and molar sound velocity were also calculated. Graphical representations of excess derived thermodynamic parameters used to explain the type and extent of intermolecular interactions

Viscosity Studies of Binary Liquid Mixture of Methyl Acrylate and Benzene and Substituted Halo Benzenes at 313.15k

Studied the binary liquid mixtures of Methyl Acrylate with Benzene (B), and Substituted Halo Benzene molecules like Chloro Benzene (CB) and Bromo Benzene (BB) at 313.15K. Initially, the density and viscosities of the mixtures are measured and this data is utilized to calculate excess properties like excess molar volume (VE), excess viscosity (ηE), and excess Gibbs free energy (ΔG*E). These excess parameter values are fitted in the Redlich–Kister Polynomial equation and the intermolecular interaction is discussed.

Acoustical Studies on Binary Mixtures of Methyl Acrylate with Benzene and Mono-Substituted Benzenes at 313.15 K

Ultrasonic velocities and Densities of binary mixtures of Methyl Acrylate (MA) with Benzene and mono-substituted Benzenes like Benzene (B), Methyl benzene (MB), and Ethyl benzene (EB) have been measured at 313.15 K, by using these data, various acoustical parameters like Isentropic compressibility (KS), Intermolecular free length (Lf), acoustic impedance (Z) and relative association (RA) were calculated, further by using these acoustical parameters, excess properties like excess ultrasonic velocities (uE), excess acoustic impedance (ZE), excess isentropic compressibility (KSE) and excess inter-molecular free-length (LfE) were calculated and fitted to Redlich-Kister equation. The existence of inter-molecular interactions between the components in the liquid mixtures was discussed.

Study of intermolecular interactions in binary mixtures of methyl acrylate with benzene and methyl substituted benzenes at different temperatures: An experimental and theoretical approach

• Reports new u and η data of methyl acrylate + aromatic hydrocarbons mixtures. • The study provides estimation of excess properties of these mixtures. • Provides information on nature and relative strength of interactions in these media. • Various empirical and semi-empirical models are used to correlate viscosity data. • The scaled particle theory (SPT) is used to predict ultrasonic speed theoretically. The ultrasonic speeds, u and viscosities, η of the binary mixtures of methyl acrylate with benzene, toluene, o -xylene, m -xylene, p -xylene, and mesitylene over the whole mole fraction range were measured at six different temperatures and at atmospheric pressure. From the experimental data, the excess isentropic compressibility, κ s E , excess ultrasonic speed, u E , excess molar isentropic compressibility, K s,m E , excess specific impedance, Z E and deviations in viscosity, Δ η have been calculated. The partial molar isentropic compressions, K ¯ s,m,1 and K ¯ s,m,2 , and excess partial molar isentropic compressions, K ¯ s,m,1 E and K ¯ s,m,2 E over the whole composition range, partial molar isentropic compressions, K ¯ s,m,1 ̂ and K ¯ s,m,2 ̂ , and excess partial molar isentropic compressions, K ¯ s,m,1 ̂ E and K ¯ s,m,2 ̂ E of the components at infinite dilution have also been calculated. The results specified the existence of weak interactions between unlike molecules, and these interactions follow the order: benzene > toluene > p -xylene > m -xylene > o -xylene > mesitylene. The magnitude of interactions was found to be dependent on the number and position of the methyl groups in these aromatic hydrocarbons.

Excess Volume, Viscosity, and Isentropic Compressibility of Methyl Acrylate + Alkane Binary Mixtures

This paper reports experimental data on densities (ρ), viscosities (η), and ultrasonic velocities (u) of four binary mixtures of methyl acrylate with heptane, decane, dodecane, and tridecane at temperatures of 303.15, 308.15, and 313.15 K and atmospheric pressure. The excess or deviation parameters such as excess volume VE, deviation in viscosity Δη, and excess isentropic compressibility KSE are evaluated and interpreted in terms of molecular interactions. Further, Grunberg–Nissan, McAllister (three-body), and Krishnan–Laddha correlation equations were used for the correlative approach and the obtained results were compared with the experimental viscosities of mixtures. A perusal of comparison shows that the kinematic viscosities calculated with the Krishnan–Laddha relation are in good agreement with the experimental values.

Light as a Catalytic Switch for Block Copolymer Architectures: Metal–Organic Insertion/Light Initiated Radical (MILRad) Polymerization

We detail a polymer synthetic methodology that merges the techniques of insertion and radical polymerization methods into a single organometallic catalyst. This metal–organic insertion/light initiated radical (MILRad) polymerization technique proves successful at polymerizing methyl acrylate (MA) and hexene, using light as a critical stimulus to activate the dormant photoresponsive nature of the insertion catalyst. In this study, we describe a novel approach that uses visible light (460 nm) to switch the catalytic activity of a cationic palladium catalyst from an insertion route to a radical process when desired. We discovered that in a mixture of MA and hexene one monomer can be selectively polymerized using light and dark cycles, respectively. As a result, this polymerization process enables the copolymerization of MA and hexene to create homo- and block copolymer architectures facilitated solely by visible light. In this work, we show the synthesis of MA homopolymers in molecular weight ranges (Mn 50–4...

Ultrasonic study of molecular interactions in binary mixtures of methyl acrylate with 1-alkanols (C4 to C10) at temperatures from (288.15 to 318.15) K

The ultrasonic speed, u of binary mixtures of methyl acrylate with 1-butanol, 1-hexanol, 1-octanol, and 1-decanol, including those of pure liquids, over the entire composition range was measured at temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15)K and at atmospheric pressure. From the experimental results, the isentropic compressibility, κs, intermolecular free length, Lf, acoustic impedance, Z, relative association, RA, molecular association MA, deviations in isentropic compressibility, Δκs, excess intermolecular free length, LfE, deviations in ultrasonic speed, Δu, excess molar isentropic compressibility, Ks,mE, excess acoustic impedance, ZE have been calculated. The partial molar isentropic compressibility, K¯s,m,1 and K¯s,m,2, and excess partial molar isentropic compressibility, K¯s,m,1E and K¯s,m,2E over the whole composition range, partial molar isentropic compressibility, K¯s,m,1° and K¯s,m,2°, and excess partial molar isentropic compressibility, K¯s,m,1°E and K¯s,m,2°E of the components at infinite dilution have also been calculated. The variations of these derived parameters indicate the presence of specific interactions between methyl acrylate and 1-alkanol molecules, which follows the order: 1-butanol>1-hexanol>1-octanol>1-decanol. The values of excess parameters are found dependent on the length of alkyl chain of 1-alkanol molecules.

Excess molar volumes and deviation in viscosities of binary liquid mixtures of acrylic esters with hexane-1-ol at 303.15 and 313.15 K

Densities and viscosities for the four binary liquid mixtures of methyl acrylate, ethyl acrylate, butyl acrylate and methyl methacrylate with hexane-1-ol at temperatures 303.15 and 313.15K and at atmospheric pressure were measured over the entire composition range. These values were used to calculate excess molar volumes and deviation in viscosities which were fitted to Redlich–Kister polynomial equation. Recently proposed Jouyban Acree model was also used to correlate the experimental values of density and viscosity. The mixture viscosities were correlated by several semi-empirical approaches like Hind, Choudhary–Katti, Grunberg–Nissan, Tamura and Kurata, McAllister three and four body model equations. A graphical representation of excess molar volumes and deviation in isentropic compressibility shows positive nature whereas deviation in viscosity shows negative nature at both temperatures for all four binary liquid mixtures. Positive values of excess molar volumes show that volume expansion is taking place causing rupture of H-bonds in self associated alcohols. The results were discussed in terms of molecular interactions prevailing in the mixtures.

Emission Enhancement, Photooxidative Stability, and Fluorescence Image Patterning of Conjugated Polymer Film via in Situ Hybridization with UV-Curable Acrylate Monomers

An acetylene–acrylate polymer hybrid film with enhanced emission, chemical resistance, and photooxidative stability was successfully prepared by the photopolymerization of acrylates in situ in poly[1-phenyl-2-(p-trimethylsilyl)phenylacetylene] (PTMSDPA) film. An acrylate mixture of methyl acrylate (MA) and trimethylol propanetriacrylate (TMPTA) easily diffused into PTMSDPA film, and simultaneously, the emission of the PTMSDPA film significantly increased. Subsequently, when the acrylate-deposited PTMSDPA film was irradiated by UV light at the appropriate irradiation power, the acrylate monomers were readily polymerized in situ in PTMSDPA film. The hybrid film still retained enhanced emission after the photopolymerization. Moreover, the hybrid film hardly dissolved in toluene even after immersing for several minutes, whereas the PTMSDPA film immediately dissolved in toluene. The hybrid film also showed photooxidative stability in air, as compared to the PTMSDPA film, due to the oxygen-blocking effect of the acrylate components. Photomasked UV irradiation of the acrylate-deposited PTMSDPA film led to a highly resolved, fluorescent image pattern on the hybrid film.

Densities and volumetric properties of binary mixtures of methyl acrylate with 1-alkanols (C 4–C 10) at different temperatures

The densities, ρ of binary mixtures of methyl acrylate with 1-butanol, 1-hexanol, 1-octanol and 1-decanol, including those of pure liquids, over the entire composition range were measured at temperatures 288.15, 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15 K and atmospheric pressure. From the experimental data, the excess molar volume, V m E, partial molar volumes, V m,1 °∞ and V m,2 °∞ , and excess partial molar volumes, V m,1 °E, ∞ and V m,2 °E, ∞ at infinite dilution were calculated. The V m E values were found positive over the whole composition range for all the mixtures and at each temperature studied, except for methyl acrylate + 1-butanol which exhibit negative V m E values, indicating the presence of specific interactions between methyl acrylate and 1-alkanol molecules. The deviations in V m E values follow the order: 1-butanol < 1-hexanol < 1-octanol < 1-decanol. It is observed that V m E values depend upon the length of alkyl chain in 1-alkanols and the interactions between methyl acrylate and 1-alkanols decrease with increase in alkyl chain length.

Densities, ultrasonic speeds and excess properties of binary mixtures of methyl acrylate with 1-butanol, or 2-butanol, or 2-methyl-1-propanol, or 2-methyl-2-propanol at temperatures from 288.15 to 318.15 K

The densities, ρ and ultrasonic speeds, u of binary mixtures of methyl acrylate with 1-butanol, 2-butanol, 2-methyl-1-propanol, and 2-methyl-2-propanol, including those of pure liquids, over the entire composition range were measured at temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15) K and atmospheric pressure. Using the experimental data, the excess molar volume, V m E and deviations in isentropic compressibility, Δ k s, partial molar volumes, V m,1 °∞ and V m,2 °∞, and excess partial molar volumes, V m,1 °E,∞ and V m,2 °E,∞ of the components at infinite dilution were calculated. The variation of these parameters with composition and temperature of the mixtures have been discussed in terms of molecular interaction in these mixtures. The values of V m E and Δ k s were found to be negative for all the mixtures at each temperature studied, indicating the presence of specific interactions between methyl acrylate and alkanol molecules. The negative V m E and Δ k s values follow the order: 1-butanol < 2-butanol < 2-methyl-1-propanol < 2-methyl-2-propanol. It is observed that the values of V m E, Δ k s, V m,1 °E,∞ and V m,2 °E,∞ depend upon the positions of hydroxyl and methyl groups in these alkanol molecules.

Densities and volumetric properties of methyl acrylate + benzene, or toluene, or o-xylene, or m-xylene, or p-xylene, or mesitylene binary mixtures at temperatures from 293.15 to 318.15 K

The densities, ρ of binary mixtures of methyl acrylate (MA) with benzene, toluene, o-xylene, m-xylene, p-xylene, and mesitylene, including those of pure liquids, over the entire composition range were measured at temperatures (293.15, 298.15, 303.15, 308.15, 313.15, and 318.15) K and atmospheric pressure. From the experimental data, the excess molar volume, V m E, partial molar volumes, V̅ m,1 ° and V̅ m,2 °, and excess partial molar volumes, V̅ m,1 °E and V̅ m,2 °E at infinite dilution were calculated. The V m E values were found negative over the whole composition range for all the mixtures and at each temperature studied, except for MA + mesitylene which exhibit positive V m E values, indicating the presence of specific interactions between MA and aromatic hydrocarbon molecules. The deviations in V m E values follow the order: benzene < toluene < p-xylene < m-xylene < o-xylene < mesitylene. It is observed that V m E values depend upon the number and position of the methyl groups in these aromatic hydrocarbons.

Densities, sound speeds, excess volumes, and excess isentropic compressibilities of methyl acrylate + 1-propanol (or 1-butanol) + hydrocarbons (n-hexane, n-heptane, cyclohexane, benzene, and toluene) at 308.15 K

Densities and sound speeds of ten ternary mixtures of methyl acrylate (1)+1-propanol (2) or 1-butanol (2)+n-hexane (3), +n-heptane (3), +cyclohexane (3), +benzene (3), and +toluene (3) have been measured at 308.15 K. The excess volumes, VE, and excess isentropic compressibilities, κEs, have been estimated. These two experimentally derived excess functions were also compared with those predicted by empirical equations of Redlich–Kister, Kohler, and Tsao–Smith. A qualitative analysis of VE and κEs data of ternary mixtures reveals that in MA (1)+1-alcohols (2)+n-hexane (3), +n-heptane (3), and +cyclohexane (3), structure disruptions are more predominant while in MA (1)+1-alcohols (2)+benzene (3) or +toluene (3) mixtures, the weak but specific structure making interactions dominate. A perusal of deviations between the experimental and calculated VE and κEs results shows that the predictive expressions give only a rough estimate of the functions for the ten studied mixtures.

Densities, Viscosities, Speeds of Sound, and Relative Permittivities for Methyl Acrylate + 1-Alcohols (C1−C6) at T = (308.15 and 318.15) K

Measurements of densities, viscosities, speeds of sound, and relative permittivities for five binary mixtures of methyl acrylate + 1-alcohols (methanol, 1-propanol, 1-butanol, 1-pentanol, and 1-hexanol) at T = (308.15 and 318.15) K are reported. The experimentally measured viscosities and speeds of sound in binary mixtures have been compared with those calculated using various semiempirical approaches. The isentropic compressibilities, molar electrical susceptibilities, and molar polarizations are calculated from the measured density, speed of sound, relative permittivity, and refractive index data. The excess volumes, excess isentropic compressibilities, excess molar electrical susceptibilities, and deviations in molar polarizations are calculated. These functions are fitted to a Redlich−Kister type equation. The variation of the Kirkwood correlation parameter has also been examined for all the binary mixtures over the whole composition range. Qualitative analysis of the various functions has been perfor...

Laser-induced thin film formation from a gaseous mixture of trimethylsilylacetylene and methyl acrylate

Under irradiation with N2 laser light, gaseous trimethylsilylacetylene (TMeSiA) and a gaseous mixture of TMeSiA and methyl acrylate (MA) produced thin films on an incident optical quartz window of an irradiation vessel. The product yield decreased with increasing partial pressure of TMeSiA. From the analysis of FT-IR spectra and X-ray photoelectron spectra of the deposited films, it was shown that SiC bond of TMeSiA was cleaved by a two-photon absorption of N2 laser light to produce trimethylsilyl radical and the silanes, R(CH3)SiCH2 (R: H3C, CHC). Trimethylsilyl radical reacted with MA at CC and CO bonds to produce SiC and SiO bonds in the film deposited from the gaseous mixture. The silanes were polymerized in each other to produce a thin film from pure TMeSiA vapor. Under irradiation with a medium pressure mercury lamp, a gaseous mixture of TMeSiA and MA produced aerosol particles in addition to the film. Polymeric species of TMeSiA was more involved in the aerosol particles rather than in the film, suggesting that collisionally induced chemical reaction takes place efficiently between excited MA and TMeSiA molecules.

Graft Copolymerization of a Binary Mixture of Methyl-Acrylate and Acrylamide onto Polyamide Films by the Mutual Method

Graft copolymerization onto polyamide-6,6 film has been studied by grafting a binary mixture of methyl acrylate and acrylamide using gamma rays from a 60Co source as initiator by the mutual method in an aqueous medium. The effect of total dose, concentration of monomer, and amount of water on the percentage grafting (Pg) has been determined. The effect of alcohols of varying chain length on the Pg of the binary mixture has been studied. They all decreased it. However, the mixed solvent system (H2O + alcohol) at certain compositions was found to enhance it. A plausible mechanism for the graft copolymerization of the binary mixture (methyl acrylate + acrylamide) onto polyamide film by the mutual method has been proposed.

Laser-induced nucleation process in aerosol particle formation from a gaseous mixture of methyl acrylate and carbon disulfide

Upon exposure to N 2 laser light, a gaseous mixture of methyl acrylate (MA) and carbon disulfide (CS 2) produced sedimentary spherical aerosol particles with a mean diameter of ≈ 0.8 μm. The product yield of the sedimentary aerosol particles deposited on a glass plate at the bottom of the cylindrical irradiation cell increased with increasing irradiation time of N 2 laser light, and with increasing laser intensity up to 3.5 ml/pulse. The IR and Raman spectra of the sedimentary aerosol particles showed the bands characteristic of poly (methyl acrylate) and carbon polymer, respectively, indicating that MA is polymerized into the aerosol particles produced from CS 2. The nucleation process of aerosol particles are briefly discussed by measuring He-Ne laser light intensity scattered by the aerosol particles and by observing the fluorescence spectrum of CS 2.

Thermodynamics of acrylic ester-organic solvent mixtures. V. viscosities and excess viscosities of alkyl acrylates-1-alcohol binary mixtures at 298.15 and 308.15 K

The viscosities for 12 binary mixtures of methyl acrylate (MA), ethyl acrylate (EA), and butyl acrylate (BA)-1-heptanol-1-octanol,-1-decanol, and-1-dodecanol were measured at 298.15 and 308.15 K. The excess viscosities were calculated from the results. The typical variations in the viscosities and excess viscisities of the mixtures as a function of ester mole fractions were explained in terms of structure-breaking dispersion and ester-ester-like interactions. The viscosities can be reasonably correlated in terms of Grunberg-Nissan, McAllister, and Auslander equations.
