Analysis of the effectiveness of organic compounds from the amine group in precipitating ions from soda production wastewater

Treating wastewater from the soda industry is a complicated and lengthy process, requiring a great deal of labor and financial resources. No method has yet been developed to eliminate the environmental damage caused by the soda industry entirely. The leakage of highly contaminated soda production wastewater into soils, groundwater, and surface water can cause corrosion of water infrastructure and deterioration of water quality for both drinking and agricultural use. Soil contamination from post-production wastewater leads to erosion and adversely affects vegetation. The work focused on the removal of chloride, sulfate, calcium, and sodium from soda production wastewater by precipitation using organic solvents such as isopropylamine (IPA), diisopropylamine (DIPA), propylamine (PA) and ethylamine (EA) in various proportions. Statistical modelling through Bayesian beta regression was used to select the amine most effectively removing the tested ions in precipitate form. The effect of precipitating agent dosage on the pH and conductivity of the solution was also investigated. Samples of wastewater obtained from the soda industry were characterized by high values of pH (up to 11.9), specific electrolytic conductivity (up to 128 mS cm−1), and high concentrations of sodium (up to 13 g L−1), chloride (up to 60 g L−1) and calcium (up to 24 g L−1) ions. Solvent-based precipitation showed that organic solvents are effective in precipitating salts from wastewater from the soda industry. Sulfate and chloride removal efficiencies of 85.1 and 34 %, respectively, were observed. Statistical analysis showed that isopropylamine was the most effective amine for ion removal.

COSMO-RS screening of organic mixtures for membrane extraction of aromatic amines: TOPO-based mixtures as promising solvents

Aromatic amines are crucial in pharmaceuticals, but their synthesis is challenging due to unfavorable reaction equilibria and the use of costly, environmentally unfriendly methods. This study presents a membrane extraction (ME) process for in situ product removal (ISPR) of aromatic amines. Using a supported liquid membrane (SLM), -methylbenzylamine (MBA) and 1-methyl-3-phenylpropylamine (MPPA) were separated from isopropyl amine (IPA). COSMO-RS was employed to screen over 200 organic mixtures, identifying twelve mixtures based on trioctylphosphine oxide (TOPO), lidocaine, and menthol as solvent candidates, due to their hydrophobicity. These mixtures were analysed for critical solvent properties including density, viscosity, hydrophobicity, and hydrogen bonding interactions. ME tests showed TOPO-thymol had the highest solvent residual and selectivity. Moreover, TOPO-thymol demonstrated solute fluxes of 9.0±3.0 g/(m2 h) for MBA, 16.5±5.4 g/(m2 h) for MPPA, and 0.7±0.3 g/(m2 h) for IPA, with selectivity values of 12.4±0.8 for MBA/IPA and 22.8±1.4 for MPPA/IPA. Compared to undecane, which had lower selectivity values of 6.9±0.8 for MBA/IPA and 10.1±1.3 for MPPA/IPA, TOPO-thymol showed superior selectivity, indicating its promise as an extractant for ME applications.

Efficient synthesis of vanillylamine through bioamination of lignin-derived vanillin by recombinant E. coli containing ω-transaminase from Caulobacter sp. D5 in dimethyl sulfoxide-water

Lignin is a plentiful and readily accessible renewable resource. Vanillylamine is a crucial raw material used to synthesize pharmaceuticals and high-value furan compounds that can be acquired by aminating lignin-derived vanillin (Van). However, effectually achieving the biocatalytic synthesis of vanillylamine has remained challenging. In this study, a dimethyl sulfoxide (DMSO)-H2O (1:9, vol/vol) bioreaction medium was constructed, and a recombinant E. coli ATA1012 carrying ω-transaminase from Caulobacter sp. D5 was used as the ω-transaminase biocatalyst to acquire the effectual biocatalytic synthesis of vanillylamine. Under optimized bioreaction conditions (37 ℃ and pH 7.5) by supplementary of isopropylamine (IPA) (Van/IPA = 1:5, mol/mol), 80–100 mM Van could be effectually converted by ATA1012 whole cells in DMSO-H2O (1:9, vol/vol) within 12 h, yielding 91.2 %–95.4 % vanillylamine, with >99 % selectivity. An efficient amination process was developed using ATA1012 with superior transaminase catalytic activity and substrate tolerance to effectively convert Van to vanillylamine in a DMSO-H2O medium.

Modification of ZSM-23 zeolite via vapor-phase transport method: Reducing the length along the unidimensional channels for enhanced catalytic performances in methanol-to-hydrocarbons

ZSM-23, a unidimensional zeolite, finds application in the methanol-to-hydrocarbons (MTH) reaction, but commonly suffers from rapid deactivation due to diffusion hindrances. Given the challenges of reducing the length along the a-axis of ZSM-23 zeolite while preserving its catalytic functions using conventional methods, this study introduces a post-modification approach inspired by the vapor-phase transport (VPT) method, wherein ZSM-23 is subjected to the vapor of an iso-propylamine (IPA) solution. The results demonstrated that the crystal lengths aligned with the micropores can be effectively reduced to less than half of the original material (115 nm vs. 289 nm), while preserving much of the microstructure and acidity. Insights into the post-treatment mechanism unveiled a coexistence of etching and re-crystallization processes during the procedure, with conditions finely adjustable by varying the concentrations of the IPA solution. The optimized modification procedure resulted in ZSM-23 zeolite demonstrating an increased C2–C4 olefin yield (62.2 % vs. 53.2 %) and enhanced stability (22 h vs. 5 h) in MTH reaction compared to the untreated sample, which can be attributed to the enhanced diffusion properties of the modified zeolite. This vapor-assisted modification protocol successfully expands the toolkit for synthesizing efficient one-dimensional zeolite for catalytic purposes.

Experimental and kinetic modeling study of iso-propylamine oxidation with SVUV-time of flight mass spectrometry

Atmospheric oxidation experiments of iso-propylamine (IPA) were conducted in a jet-stirred reactor over the temperature range from 550 to 870 K at fuel-equivalence ratios of 0.5 and 2.0. A combination of synchrotron vacuum ultraviolet (SVUV) photoionization and time-of-flight mass spectrometry (TOFMS) was utilized to identify and quantify oxidation products and intermediates. Compared to the previous n-propylamine (NPA) low-temperature oxidation [Proc. Combust. Inst., 39 (2023) 295–303.], some intermediates and products were newly observed among the 34 detected species, including nitrosyl hydride, methylamine, acetonitrile, nitrous oxide, ethyl isocyanide, propanenitrile, 2-propanimine, n-methylformamide and 2-methylallylamine. A kinetic model consisting of 815 species and 4402 reactions was developed based on the iso-propanol model [Prog. Energy Combust. Sci. 67 (2018) 31–68.] and an ethylamine model [Prog. Energy Combust. Sci. 44 (2014) 40–102.]. The onset temperature of IPA and O2 consumption is 750 K under both lean and rich conditions. Rate-of-production (ROP) and sensitivity analyses were performed at 800 K to illustrate the reacting paths from parent fuel to major intermediates and products, and identify the most sensitive reactions. H2O2(+M) = 2OH(+M) is the most sensitive reaction with a promoting effect on IPA consumption while 2HO2 = H2O2+O2 is the most inhibiting one. Important N-containing pollutants like NH3, NOx, HCN, CH3NH2 and so on were analyzed with respect to their reaction routes. (CH3)2CNH is abundant due to the H-abstraction reactions between tC3H6NH2 radical with O2. This work was made for gaining a more comprehensive insight into the oxidation of IPA and make a foundation for further exploring amine chemistry.

Efficient separation of photo-generated carriers for in-situ induction of PDI cation radicals to enhance the photocatalytic performance of PDI supramolecules

In order to investigate whether the formation of hydrogen bonds can affect the degradation products of pollutants, a photocatalyst PDI-SE was obtained by end substituting perylene tetracarboxylic dianhydride with serine (SE) in this paper. As a reference, PDI-IS with isopropylamine (IS) terminal alkyl substitution was synthesized simultaneously. Their photocatalytic performance to decompose phenol and tetrabromobisphenol A (TBBPA) were investigated. PDI-SE could degrade 79.3% of phenol or 68.4% of TBBPA within 4 h under visible light. The degradation products of TBBPA were tracked using high-resolution mass spectrometry. The morphology, composition, structure, and optoelectronic properties of two photocatalysts, particularly their transient absorption spectra and fluorescence lifetime were studied. We also conducted theoretical calculations on their binding energy with phenol or TBBPA, distribution and separation of electron and hole of excited state PDI-SE and PDI-IS supramolecules. Due to the formation of hydrogen bonds the binding energy of PDI-SE with phenol or TBBPA is 1.24 eV or 1.99 eV, which is stronger than that of PDI-IS (0.85 eV or 1.66 eV). Although both PDI-SE and PDI-IS can form free radical cations in excited states, the high separation of electrons and holes of PDI-SE leads to a longer lifetime of free radical cations, so caused its excellent photocatalytic activity compared to PDI-IS. This article proposes a new strategy based on molecular design to promote efficient separation of photogenerated electrons and holes, thereby forming stronger oxidizing PDI cationic radicals in situ to enhance the photocatalytic performance of PDI supramolecules.

γ-Glutamylation of Isopropylamine by Fermentation.

Glutamylation yields N-functionalized amino acids in several natural pathways. γ-Glutamylated amino acids may exhibit improved properties for their industrial application, e. g., as taste enhancers or in peptide drugs. γ-Glutamyl-isopropylamide (GIPA) can be synthesized from isopropylamine (IPA) and l-glutamate. In Pseudomonas sp. strain KIE171, GIPA is an intermediate in the biosynthesis of l-alaninol (2-amino-1-propanol), a precursor of the fluorochinolone antibiotic levofloxacin and of the chloroacetanilide herbicide metolachlor. In this study, fermentative production of GIPA with metabolically engineered Pseudomonas putida KT2440 using γ-glutamylmethylamide synthetase (GMAS) from Methylorubrum extorquens was established. Upon addition of IPA during growth with glycerol as carbon source in shake flasks, the recombinant strain produced up to 21.8 mM GIPA. In fed-batch bioreactor cultivations, GIPA accumulated to a titer of 11 g L-1 with a product yield of 0.11 g g-1 glycerol and a volumetric productivity of 0.24 g L-1 h-1 . To the best of our knowledge, this is the first fermentative production of GIPA.

Dual-function transaminases with hybrid nanoflower for the production of value-added chemicals from biobased levulinic acid.

The U.S. Department of Energy has listed levulinic acid (LA) as one of the top 12 compounds derived from biomass. LA has gained much attention owing to its conversion into enantiopure 4-aminopentanoic acid through an amination reaction. Herein, we developed a coupled-enzyme recyclable cascade employing two transaminases (TAs) for the synthesis of (S)-4-aminopentanoic acid. TAs were first utilized to convert LA into (S)-4-aminopentanoic acid using (S)-α-Methylbenzylamine [(S)-α-MBA] as an amino donor. The deaminated (S)-α-MBA i.e., acetophenone was recycled back using a second TAs while using isopropyl amine (IPA) amino donor to generate easily removable acetone. Enzymatic reactions were carried out using different systems, with conversions ranging from 30% to 80%. Furthermore, the hybrid nanoflowers (HNF) of the fusion protein were constructed which afforded complete biocatalytic conversion of LA to the desired (S)-4-aminopentanoic acid. The created HNF demonstrated storage stability for over a month and can be reused for up to 7 sequential cycles. A preparative scale reaction (100mL) achieved the complete conversion with an isolated yield of 62%. Furthermore, the applicability of this recycling system was tested with different β-keto ester substrates, wherein 18%-48% of corresponding β-amino acids were synthesized. Finally, this recycling system was applied for the biosynthesis of pharmaceutical important drug sitagliptin intermediate ((R)-3-amino-4-(2,4,5-triflurophenyl) butanoic acid) with an excellent conversion 82%.

Biotransamination of Furan-Based Aldehydes with Isopropylamine: Enzyme Screening and pH Influence.

Furan-based amines are highly valuable compounds which can be directly obtained via reductive amination from easily accessible furfural, 5-(hydroxymethyl)furfural (HMF) and 2,5-diformylfuran (DFF). Herein the biocatalytic amination of these carbonyl derivatives is disclosed using amine transaminases (ATAs) and isopropylamine (IPA) as amine donors. Among the different biocatalysts tested, the ones from Chromobacterium violaceum (Cv-TA), Arthrobacter citreus (ArS-TA), and variants from Arthrobacter sp. (ArRmut11-TA) and Vibrio fluvialis (Vf-mut-TA), afforded high levels of product formation (>80 %) at 100-200 mM aldehyde concentration. The transformations were studied in terms of enzyme and IPA loading. The pH influence was found as a key factor and attributed to the imine/aldehyde equilibrium that can arise from the high reactivity of the carbonyl substrates with a nucleophilic amine such as IPA.

THE EFFICACY OF ISOPROPYL AMINE GLYPHOSATE 165 SL HERBICIDE EFFECT ON WEED CONTROL OF COCONUT CULTIVATION

Coconut plants are an important commodity for Indonesian people. In the cultivation process, coconut plants need a suitable environment for growth and production. One of the problems in cultivation is weeds. Weeds have a negative impact on cultivated plants, therefore appropriate control measures are needed. So far, the most effective weed control is chemical methods using herbicides. One of the herbicides that can be used is the herbicide with isopropyl amine glyphosate 165 SL. The aim of the experiment was to determine the efficacy of the herbicide isopropyl amine glyphosate 165 SL for controlling weeds in coconut cultivation was conducted from February to June 2022 at Pariaman City, West Sumatra Province. The experimental units were laid out according to a Randomized Block Design with 7 treatments and 3 groups as replications. The treatment was herbicide isopropyl amine glyphosate 165 SL at doses of 3.50 l ha-1, 5.25 l ha-1, 7.00 l ha-1, 8.75 l ha-1, 10.00 l ha-1, manual weeding and control (without weeding). The results of the research show that (1) The herbicide isopropyl amine glyphosate 165 SL can generally control weeds in coconut cultivation up to 12 weeks after application because the weed biomass in the treatment plot is relatively the same as manual weeding and is lighter than the control; (2) Herbicide isopropyl amine glyphosate 165 SL with a dose range of 3.50 l/ha – 10.50 l ha-1 up to 6 weeks after application does not show symptoms of phytotoxicity in coconut plants.

Possibility of glyphosate-resistant goosegrass (Eleusine indica) in citrus fields in Rejang Lebong Districts, Bengkulu, Indonesia

Abstract. Simarmata M, Apriantonedi R, Setyowati N, Pujiwati H. 2023. Possibility of glyphosate-resistant goosegrass (Eleusine indica) in citrus fields in Rejang Lebong Districts, Bengkulu, Indonesia. Biodiversitas 24: 3633-3638.Weed abundances dominated by goosegrass (Eleusine indica L.) are a major constraint in the citrus fields of Rejang Lebong District, Province of Bengkulu, Indonesia. The objectives of this research were to investigate weed control methods applied by citrus farmers, analyze the dominant weed, and study the possibility of glyphosate resistance in goosegrass. A survey was conducted by interviewing three citrus farmers regarding weed control measures, followed by weed assessment in 10 sampling plots of each location. Then, field trials were conducted to evaluate glyphosate efficacy on weeds in the three locations of citrus fields. The survey found that glyphosate has been applied for weed control up to 4 L ha-1( 1.92 kg a.i. ha-1 of isopropyl amine salt) 2 to 3 times a year, and the farmers found that some weeds were resistant to glyphosate. Weed assessment showed that goosegrass is a dominant species with a summed dominance ratio (SDR) of 67.1, 70.8, and 79.0% at each location, respectively. The field trials observed that the levels of survival weeds in the experimental plots treated with glyphosate at 0.5, 1.0, 2.0, 4.0, and 8.0 L ha-1were 94-95%, 83-85.3%, 70-73.3%, 20-29%, and 10-12.3%, respectively. Goosegrass was identified as the survivor's weeds. The glyphosate doses (LD50) required to eradicate 50% of the weed populations ranged between 2 and 4 L ha-1 at the three sites. This study proved that goosegrass in the citrus groves of Rejang Lebong District, Bengkulu, is resistant to glyphosate.

Lipase catalyzed chemo-enzymatic synthesis of propranolol: A newer enzymatic approach

The biocatalytic processes are greener and safer alternatives for synthesis of drug and drug intermediates. This study reports one such approach of chemo-enzymatic synthesis of propranolol, a β-adrenergic receptor blocker. A green synthetic route was employed for synthesis of propranolol using enzymatic kinetic resolution. Racemic mixture of secondary alcohol [1-chloro-3-(naphthalen-1-yloxy)propan-2-ol] (RS)-5 was synthesized chemically in two step reaction and further its enzymatic kinetic resolution was carried out by using lipase to synthesize enantiomeric forms (R)-5 and S-(6) of propranolol. The kinetic resolution of (RS)-5 involves the transesterification of secondary racemic alcohol in which vinyl acetate is used as acyl donor. Initially, we screened commercially available lipases for kinetic resolution and of all the screened lipases Addzyme 001 showed the best results. The several reaction parameters such as organic solvent, acyl donor, temperature, reaction time and enzyme concentration were optimized to improve rate of reaction and to achieve maximum enantioselectivity. Addzyme 001 at 40 mg shows the maximum conversion rate of 49% using cyclohexane as the organic solvent, vinyl acetate as the acyl donor and it was found that the reaction yield was higher for (R)-5 along with the (S)-6 (eep = 98%, ees = 97%) at 40 °C in 48 h. Further, the treatment of (R)-5 with isopropyl amine resulted into formation of (S)-propranolol eep = 98%, and overall yield 29% independently. To synthesize (R)-propranolol, S-(6) acetate was produced enzymatically and was further deacylated by chemical hydrolysis for the production of (R)-propranolol. This study reports newer approach for synthesis of (R) and (S) propranolol using chemoenzymatic route.

Biodegradation of atrazine using selected marine bacteria: Possibilities for treating pesticide - contaminated wastewater

The use of pesticides including atrazine can cause detrimental problems to the environment. Atrazine, 2-chloro-4-(ethylamine)-6- (isopropyl amine)-s-triazine, is one of the widely used herbicides. In this work, thirteen pure bacterial strains were isolated from water and sediments collected from different sites along Alexandria Mediterranean Coast and were evaluated for their efficacy to biodegrade atrazine at three elevated concentrations (I: 109, II: 299 &III: 438 mg/L) for 7 days. Atrazine residues were determined using gas chromatography (GC). Marine isolates exhibited very high atrazine biodegradation with removal efficacy ranging between 15.79 and 75.49, 77.97–97.13 and 27.4–87.6% at three elevated concentrations, respectively. The results indicated that 5 of the isolates (E7, 8, 9, 11 and 13) were the most efficient, and active as atrazine bio-degraders. They were affiliated as Bacillus pacificus strain MCCC 1A06182 (E7 and E8), Bacillus cereus strain ATCC 14579 (E9) and Bacillus paramycoides strain MCCC 1A04098 (E11 and E13). Results obtained provided evidence that marine environment is a natural, rich and renewable source of bacteria with marvelous metabolic capabilities for efficient bioremediation of atrazine-contaminated aquatic environments or wastewater.

Evaluation of the herbicide glyphosate, (aminomethyl)phosphonic acid, and glyphosate-based formulations for genotoxic activity using in vitro assays.

Glyphosate, the most heavily used herbicide world-wide, is applied to plants in complex formulations that promote absorption. The National Toxicology Program reported in 1992 that glyphosate, administered to rats and mice at doses up to 50,000 ppm in feed for 13 weeks, showed little evidence of toxicity, and no induction of micronuclei was observed in the mice in this study. Subsequently, mechanistic studies of glyphosate and glyphosate-based formulations (GBFs) that have focused on DNA damage and oxidative stress suggest that glyphosate may have genotoxic potential. However, few of these studies directly compared glyphosate to GBFs, or effects among GBFs. To address these data gaps, we tested glyphosate, glyphosate isopropylamine (IPA), and (aminomethyl)phosphonic acid (AMPA, a microbial metabolite of glyphosate), 9 high-use agricultural GBFs, 4 residential-use GBFs, and additional herbicides (metolachlor, mesotrione, and diquat dibromide) present in some of the GBFs in bacterial mutagenicity tests, and in human TK6 cells using a micronucleus assay and a multiplexed DNA damage assay. Our results showed no genotoxicity or notable cytotoxicity for glyphosate or AMPA at concentrations up to 10 mM, while all GBFs and herbicides other than glyphosate were cytotoxic, and some showed genotoxic activity. An in vitro to in vivo extrapolation of results for glyphosate suggests that it is of low toxicological concern for humans. In conclusion, these results demonstrate a lack of genotoxicity for glyphosate, consistent with observations in the NTP in vivo study, and suggest that toxicity associated with GBFs may be related to other components of these formulations.

Facilitated solvent screening for membrane-based extraction of chiral amines via a priori simulations

Chiral amines are important building blocks in the pharmaceutical industry. A challenge for the current industry is their difficult synthesis procedures, which employ harsh operating conditions or have an unfavourable equilibrium constant. An interesting strategy in improving the reaction equilibrium is the use of in-situ product removal via membrane extraction (ME) using supported liquid membranes (SLM), which is explored in this work. More specifically, the separation of the product amines α-methylbenzylamine (MBA) and 1-methyl-3-phenylpropylamine (MPPA) from the donor amine isopropyl amine (IPA) by employing SLMs is investigated in this study. A difficulty in SLM-applications is the solvent selection, which mostly requires the use of extensive liquid–liquid extraction (LLE) testing. In this work, COSMO-RS is used to perform a fast and simplified screening of almost 400 ILs, which led to a shortlist definition of fourteen ILs. For these fourteen ILs, critical solvent properties (i.e., density, viscosity and phase miscibility) were analysed experimentally and compared to simulations in COSMO-RS. Finally, four promising ionic liquids were selected for further LLE- and ME-testing, namely trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide ([P6,6,6,14][N(Tf)2]), 1-methyl-1-propylpyrro-lidinium bis(trifluoromethylsulfonyl)imide ([C3mPyr][N(Tf)2]), 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C6mim][N(Tf)2]) and triethylsulfonium bis(trifluoromethylsulfonyl)imide ([S2,2,2][N(Tf)2]). Based on wettability testing of four polymeric porous substrates (i.e., PTFE, PES, PSf and PVDF), the PTFE-support was chosen for the stability tests, due to its very high hydrophobicity. The LLE- and stability tests showed that [P6,6,6,14][N(Tf)2] has the highest MBA/IPA- and MPPA/IPA-selectivity and the best SLM-stability of all the tested ILs. Comparative SLM-testing with the benchmarking solvent undecane showed that the IL [P6,6,6,14][N(Tf)2] has a higher SLM-selectivity than undecane at elevated temperatures, while no decrease in its stability was observed.
