An imidazolium-based ionene blended with crosslinked PEO as a novel polymer membrane for selective CO₂ separation was written by Kammakakam, Irshad;Rao, Anil H. N.;Yoon, Hee Wook;Nam, SangYong;Park, Ho Bum;Kim, Tae-Hyun. And the article was included in Macromolecular Research in 2014.Product Details of 4074-88-8 This article mentions the following:

A novel imidazolium-based ionene was mixed with a di(ethylene glycol) diacrylate that was subsequently photocrosslinked to form a blend membrane useful for CO₂/N₂ gas separation The crosslinked poly(ethylene oxide) (PEO) offered a mech. stable matrix with a high CO₂ affinity. The ionene loading affected both the structure and CO₂ separation performance of the blend membranes as demonstrated by varying the ionene content in three levels, 1:1, 2:1, and 3:1 (ionene:crosslinker) by weight The CO₂ solubility of the membrane dramatically increased with the ionene loading level, and a high CO₂/N₂ permselectivity of 33.5 was obtained for the [3II-cPEO][TFSI]. The imidazolium-based ionene blend membranes prepared with crosslinked PEO (II-cPEO) also displayed good thermal and mech. stability. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8Product Details of 4074-88-8).

Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. The oxygen atom of the strongly polarized O鈥旽 bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Product Details of 4074-88-8

Effects on Pseudosuccinea columella Snails Exposed to Origanum vulgare and Thymus vulgaris Volatile Oils was written by do Carmo Sperandio, Natania;Vidal, Maria Larissa Bitencourt;da Silva, Ygor Henrique;Ito, Mitsue;Costa, Adilson Vidal;de Queiroz, Vagner Tebaldi;Ignacchiti, Mariana Drummond Costa;Boeloni, Jankerle Neves;Martins, Isabella Vilhena Freire. And the article was included in Revista Brasileira de Farmacognosia in 2022.Recommanded Product: 5-Isopropyl-2-methylphenol This article mentions the following:

Fasciolosis is an anthropozoonosis of clin. and economic importance that affects several mammals. The causative agent, Fasciola hepatica, has as an obligate intermediate host, the snail Pseudosuccinea columella; therefore, control actions against the mollusks are essential to control the disease. This study aims to evaluate the effect of volatile oils of Origanum vulgare L. and Thymus vulgaris L., both species members of Lamiaceae family, and their resp. major compounds, carvacrol and thymol, as an alternative in the control of the American ribbed fluke snail. The specimens were immersed in solutions with concentrations of 0.025% (mv-1), 0.05% (mv^-1), and 0.1% (mv^-1) and analyzed at 30 min, 2 h, 6 h, 12 h, and 24 h in relation to motility, adhesion in the plate, response to painful stimulus, and mortality. For ovigerous masses, the interruption or not of embryonic development was analyzed, with observations every 72 h up to 18 days. All compounds promoted the mortality of mollusks and the paralysis of the embryonic development. The test constituents promoted mortality after 30 min. Histol. analyses indicated the occurrence of necrosis, mainly in the digestive gland and in the albumen gland and disorganized connective tissue. In the experiment, the researchers used many compounds, for example, 5-Isopropyl-2-methylphenol (cas: 499-75-2Recommanded Product: 5-Isopropyl-2-methylphenol).

5-Isopropyl-2-methylphenol (cas: 499-75-2) belongs to alcohols. The oxygen atom of the strongly polarized O鈥旽 bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Recommanded Product: 5-Isopropyl-2-methylphenol

COSMO Study on the Heptane-Toluene-DMF/DEG-KSCN Liquid-Liquid Equilibrium System was written by Fernanda Bonfim de Souza, Beatriz;Lenhare, Stephanie;Cristaldo Heck, Stenio;Zuber, Andre;Beneti, Stephani Caroline;Zanette, Andreia Fatima;Filho, Lucio Cardozo. And the article was included in Industrial & Engineering Chemistry Research in 2022.Reference of 111-46-6 This article mentions the following:

The class of aromatic hydrocarbons is one of the most important in the petrochem. industry. As they are in a multicomponent mixture with aliphatics, separation represents a huge challenge given the proximity of their b.ps., and liquid-liquid extraction represents a good alternative to conventional separation processes. In this paper, liquid-liquid equilibrium data of a heptane-toluene-dimethylformamide (DMF)-diethylene glycol (DEG) system in the presence and absence of potassium thiocyanate salt were obtained and used to study solvation of ions in the DMF-DEG polar mixture solvent, using COnductor-like Screening MOdel (COSMO) modeling. It was verified that the solvation complexes failed to describe the system equilibrium despite the otherwise expected. COSMO-RS (realistic solvents) calculations of the unsolvated ions presented better approximation with exptl. data compared to COSMO-SAC (segment activity coefficient) ones. The best simulation obtained with nonsolvated ions occurred probably due to 蟺 electron interactions with ion charge and hydrogen bond with the solvent. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Reference of 111-46-6).

2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Reference of 111-46-6

Metabolic, cellular and defense responses to single and co-exposure to carbamazepine and methylmercury in Dreissena polymorpha was written by Baratange, Clement;Paris-Palacios, Severine;Bonnard, Isabelle;Delahaut, Laurence;Grandjean, Dominique;Wortham, Laurence;Sayen, Stephanie;Gallorini, Andrea;Michel, Jean;Renault, David;Breider, Florian;Loizeau, Jean-Luc;Cosio, Claudia. And the article was included in Environmental Pollution (Oxford, United Kingdom) in 2022.Category: alcohols-buliding-blocks This article mentions the following:

Carbamazepine (CBZ) and Hg are widespread and persistent micropollutants in aquatic environments. Both pollutants are known to trigger similar toxicity mechanisms, e.g. reactive oxygen species (ROS) production Here, their effects were assessed in the zebra mussel Dreissena polymorpha, frequently used as a freshwater model in ecotoxicol. and biomonitoring. Single and co-exposures to CBZ (3.9 渭g L-1) and MeHg (280 ng L-1) were performed for 1 and 7 days. Metabolomics analyses evidenced that the co-exposure was the most disturbing after 7 days, reducing the amount of 25 metabolites involved in protein synthesis, energy metabolism, antioxidant response and osmoregulation, and significantly altering cells and organelles structure supporting a reduction of functions of gills and digestive glands. CBZ alone after 7 days decreased the amount of 伪-aminobutyric acid and had a moderate effect on the structure of mitochondria in digestive glands. MeHg alone had no effect on mussels metabolome, but caused a significant alteration of cells and organelles structure in gills and digestive glands. Single exposures and the co-exposure increased antioxidant responses vs control in gills and digestive glands, without resulting in lipid peroxidation, suggesting an increased ROS production caused by both pollutants. Data globally supported that a higher number of hyperactive cells compensated cellular alterations in the digestive gland of mussels exposed to CBZ or MeHg alone, while CBZ + MeHg co-exposure overwhelmed this compensation after 7 days. Those effects were unpredictable based on cellular responses to CBZ and MeHg alone, highlighting the need to consider mol. toxicity pathways for a better anticipation of effects of pollutants in biota in complex environmental conditions. In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Category: alcohols-buliding-blocks).

Indium(III)-Catalyzed Synthesis of Primary Carbamates and N-Substituted Ureas was written by Jain, Isha;Malik, Payal. And the article was included in Synlett in 2022.Application In Synthesis of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol This article mentions the following:

An indium triflate-catalyzed synthesis of primary carbamates RXC(O)NH₂ [R = i-Bu, Bn, Ph, etc.; X= O, N] from alcs. and urea as an ecofriendly carbonyl source was developed. Various linear, branched, and cyclic alcs. were converted into the corresponding carbamates in good to excellent yields. This method also provided access to N-substituted ureas by carbamoylation of amines. All the products were obtained by simple filtration or crystallization, without the need for chromatog. purification Mechanistic investigations suggested that the carbamoylation reaction proceeded through activation of urea by O-coordination with indium, followed by nucleophilic attack by the alc. or amine on the carbonyl center of urea. The inexpensive and easily available starting materials and catalyst, the short reaction times, and the ease of product isolation highlighted the inherent practicality of the developed method.

Efficient asymmetric synthesis of chiral alcohols using high 2-propanol tolerance alcohol dehydrogenase SmADH2 via an environmentally friendly TBCR system was written by Yang, Zeyu;Fu, Hengwei;Ye, Wenjie;Xie, Youyu;Liu, Qinghai;Wang, Hualei;Wei, Dongzhi. And the article was included in Catalysis Science & Technology in 2020.Quality Control of (R)-1-(3-Chlorophenyl)ethanol This article mentions the following:

Alc. dehydrogenases (ADHs) together with the economical substrate-coupled cofactor regeneration system play a pivotal role in the asym. synthesis of chiral alcs.; however, severe challenges concerning the poor tolerance of enzymes to 2-propanol and the adverse effects of the byproduct, acetone, limit its applications, causing this strategy to lapse. Herein, a novel ADH gene smadh2 was identified from Stenotrophomonas maltophilia by traditional genome mining technol. The gene was cloned into Escherichia coli cells and then expressed to yield SmADH2. SmADH2 has a broad substrate spectrum and exhibits excellent tolerance and superb activity to 2-propanol even at 10.5 M (80%, volume/volume) concentration Moreover, a new thermostatic bubble column reactor (TBCR) system is successfully designed to alleviate the inhibition of the byproduct acetone by gas flow and continuously supplement 2-propanol. The organic waste can be simultaneously recovered for the purpose of green synthesis. In the sustainable system, structurally diverse chiral alcs. are synthesized at a high substrate loading (>150 g L^-1) without adding external coenzymes. Among these, about 780 g L^-1 (6 M) Et acetoacetate is completely converted into Et (R)-3-hydroxybutyrate in only 2.5 h with 99.9% ee and 7488 g L^-1 d^-1 space-time yield. Mol. dynamics simulation results shed light on the high catalytic activity toward the substrate. Therefore, the high 2-propanol tolerance SmADH2 with the TBCR system proves to be a potent biocatalytic strategy for the synthesis of chiral alcs. on an industrial scale.
