Cellulose acetate (CA) grafted with imidazole ionic liquids (CA-ILs) was synthesized by reacting CA with imidazole ionic liquids ([HO2CMmim]Cl, [HO2CEtmim]Cl, and [HO2CMmim]Br) by using THF as the solvent and pyridine as the catalyst. The CA and CA-IL films were fabricated by using the casting solution method. The CA-IL films exhibited good film forming ability and mech. properties. The successful grafting of CA with imidazole ionic liquids was confirmed by Fourier transform IR (FTIR), 1H NMR, SEM, and elemental anal., and the grafting degrees were 2.24, 2.45, and 3.30%, resp. The CO2 permeation properties of the CA-IL films were 65.5, 105.6, and 88.3 Barrer, increased up to 2.0, 3.2, and 2.7 times, resp., as compared to pure CA (32.6 Barrer). The CO2/CH4 selectivities of the CA-IL films were 15.6, 12.6, and 19.2, increased up to 1.7, 1.4, and 2.1 times, resp., as compared to pure CA (9.26). Therefore, it can be concluded that the imidazole ionic liquids are immensely useful for improving the gas separation performance of CA films.

Wu, Ke; Yu, Yunlong; Hou, Zhaonan; Guan, Xin; Zhao, Hongran; Liu, Sen; Yang, Xi; Fei, Teng; Zhang, Tong published the artcile< A humidity sensor based on ionic liquid modified metal organic frameworks for low humidity detection>, Recommanded Product: 1-carboxymethyl-3-methylimidazolium chloride, the main research area is ionic liquid metal organic framework polyelectrolyte humidity sensor stability.

Low humidity detection has always been a challenge in the field of humidity detection. Humidity sensors base on ionic liquid modified metal organic frameworks (MOFs) derived polymer films were prepared in this work. The ionic liquid ligand was uniformly introduced in the frameworks of UIO-66 to enhance the hydrophilicity of sensing materials, the caused defects sites are beneficial for adsorption and desorption, and the MOFs based functional films were easily obtained by in situ photoinduced thiol-ene click reaction. The obtained humidity sensor exhibits a linear response in low relative humidity (RH) range (5% RH – 30% RH) with a tiny humidity hysteresis (∼0.2% RH) and short response time to humidity change (response/recovery time is 0.6 s/1.7 s, resp.).

Demetrio da Silva, Vinicius; de Barros, Italo Ribeiro; da Conceicao, Debora K. Silva; de Almeida, Kauana Nunes; Schrekker, Henri Stephan; Amico, Sandro C.; Jacobi, Marly M. published the artcile< Aramid pulp reinforced hydrogenated nitrile butadiene rubber composites with ionic liquid compatibilizers>, Quality Control of 700370-07-6, the main research area is aramid pulp reinforced hydrogenated nitrile butadiene rubber composite compatibilizer.

Although carbon black is an effective reinforcement for most rubbers, its replacement by other fillers would be beneficial. Aramid fibers are used in a range of applications in the rubber industry, providing dimensional stability prior to vulcanization and improving the mech. properties of the elastomeric product. Nevertheless, their relatively inert surface is an obstacle in the exploitation of their full potential. In this work, two ionic liquids were investigated as compatibilizers in the preparation of hydrogenated nitrile butadiene rubber composites with aramid pulp and carbon black fillers. The materials were characterized using swelling, hardness and tensile tests, differential scanning calorimetry, thermal gravimetric anal., and IR spectroscopy. The carbon black-free composite prepared from aramid pulp treated with 1.0 wt% of 1-carboxymethyl-3-methylimidazolium chloride outperformed all other studied materials, presenting a higher modulus at 100% strain (7.31 MPa), while maintaining high strain at break. Thus, ionic liquids were found to potentialize the aramid reinforcement effect in these rubber composites. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 137, 48702.

The creation of carbon-carbon bonds is still a highly required topic in organic chem. for the capacity to give a wide variety of new products of industrial value. Accordingly, the Knoevenagel condensation between activated methylene compounds and aldehydes is one of the most known carbon coupling reactions. In this work, the catalytic activity of imidazolium-based ionic liquids (1-butyl-3-methylimidazolium acetate, 1-butyl-3-methylimidazolium chloride, 1-methyl-3-carboxymethylimidazolium chloride) was studied under solvent-free conditions and compared with that of sodium salts (sodium chloride, sodium acetate). Mass spectrometric techniques were used to monitor the formation of the reaction products and to detect the key intermediates of the process. Based on the catalyst employed different reaction mechanisms were highlighted, thus laying the foundation for the design of more specific and efficient catalysts.

Perchacz, Magdalena; Matejka, Libor; Konefal, Rafal; Seixas, Leandro; Livi, Sebastien; Baudoux, Jerome; Benes, Hynek; Donato, Ricardo K. published the artcile< Self-Catalyzed Coupling between Bronsted-Acidic Imidazolium Salts and Epoxy-Based Materials: A Theoretical/Experimental Study>, Related Products of 700370-07-6, the main research area is self catalysis Bronsted acidic imidazolium salt epoxide coupling.

Herein we present a comprehensive study on the role of Bronsted-acidic imidazolium ionic liquids (ILs) and imidazolium salts promoting the reaction between carboxyl and epoxide groups in a controlled manner at solvent-free and mild conditions. ILs were evaluated toward their ability to self-catalyze reactions between carboxyl groups and epoxy rings. Thus, an epoxy model reactant denoted Ph glycidyl ether (PGE) was reacted with different ILs, and the reaction kinetics was followed by time-dependent FTIR spectroscopy. The resulting products were characterized by 1H NMR and MALDI-TOF, which also allowed a comprehensive investigation of the reaction mechanism by following the reaction intermediates formation. The detected intermediates were then evaluated by d. functional theory (DFT) simulations to calculate their energy profiles, revealing the preferred mechanism pathways. These mono-, bi-, and tetra-functionalized ILs (with carboxyl groups) acted as all-in-one reaction systems for materials synthesis or modification, with the potential of producing a broad range of epoxy based materials via metal catalyst-free coupling reactions. A solvent-free self-catalyzed platform for reactions with epoxy materials at mild temperatures based on Bronsted-acidic imidazolium salts.

Song, Honghong; Zhang, Jing; Song, Pengfei; Xiong, Yubing published the artcile< Maize-like ionic liquid@polyaniline nanocomposites for high performance supercapacitor>, Synthetic Route of 700370-07-6, the main research area is polyaniline nanocomposite ionic liquid supercapacitor tunable morphol.

In this study, ionic liquids (IL) containing carboxyl and different alkyl chains were fabricated and used to dope polyaniline (PANI). The results revealed that IL-PANI composites could be facilely obtained via template-free polymerization of aniline using ammonium persulfate as the oxidant. The as-prepared IL-PANI composites were measured by FT-IR, XPS, and SEM. Electrochem. performances of IL-PANI nanocomposites were investigated by cyclic voltammetry and galvanostatic charge/discharge. The results indicate that the alkyl chains of ILs have an important influence on the morphol. and capacitance performance of IL-PANI electrode materials. With the shorter alkyl group in ILs, IL-PANI materials presented higher specific capacitance. Especially, 1-vinyl-3-carboxymethyl-imidazolium chloride ([VCMIm]Cl)-PANI composite presented the highest specific capacitance. Cycling performance measurement demonstrated that 82% capacitance retention could be achieved after 1000 cycles in 0.5 M H2SO4 aqueous solution Therefore, our strategy provides a new technique for PANI nanocomposites with tunable morphol. and high performance.

This paper presents the features of corn stover pretreated under mild conditions in aqueous solution of a carboxylic acid functionalized ionic liquids 1-carboxymethyl-3-methylimidazolium chloride (IL-COOH). The results revealed that such pretreatment selectively removed hemicelluloses in corn stover, resulting in cellulose- and lignin-rich pulps with moderate enzymic reactivity. The corn stover pretreated in 40 wt% IL-COOH at 120 °C for 4 h demonstrated increases in cellulose and lignin contents from 37.9% to 55.6%, and 21.1% to 26.5%, resp., while decrease in the content of hemicellulose from 24.4% to 9.34%. Subsequent enzymic hydrolysis of the pulps achieved from pretreatment in 50 wt% IL-COOH aqueous solution at 105 °C for 4 h produced 0.32 g.g-1 glucose and 0.45 g.g-1 total reducing sugars. The recyclability and reusability of IL-COOH in the pretreatment system was also investigated.
