And the article was included in Polymer in 2019.Application of 915358-85-9 This article mentions the following:

Benzene and cyclohexane are both important raw materials in polymer chem. industry. However, they are hard to be separated via the traditional distilling methods. In this work, ionic liquid copolymerized waterborne polyurethane (IL-co-PU) membranes were proposed for the pervaporation separation of benzene/cyclohexane mixtures The results, including swelling rate, diffusion coefficients, partial flux, permeance and selectivity, showed that the IL-co-PU membranes could preferentially absorb and transfer benzene mols. rather than cyclohexane. The ILs might have functioned as facilitated transporter in the membranes. The permeation flux and separation factor of the IL-co-PU membranes increased simultaneously with the increase of IL contents. That is, these membranes had no trade-off between permeability and selectivity, which most of the polymer membranes suffered. With consideration of the good performance and easy handling property of the IL-co-PU membranes, they are of great potential in pervaporation separation of benzene/cyclohexane mixtures In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9Application of 915358-85-9).

1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Application of 915358-85-9

Poly(ionic liquid)-Coated Meshes with Opposite Wettability for Continuous Oil/Water Separation was written by Deng, Xi;Zhang, Jingshun;Zhang, Liren;Cheng, Guiren;Chen, Bihua;Zhang, Yongya;Gao, Guohua. And the article was included in Industrial & Engineering Chemistry Research in 2020.Application of 915358-85-9 This article mentions the following:

A series of oil/water separation membranes with tunable surface wettability based on poly(ionic liquid)s (PILs) were prepared via a facile one-step photopolymerization of N-vinylimidazolium ionic liquids and divinylbenzene on meshes. The wettability of PIL-based membranes (PILMs) was adjusted by the structures of PILs, specifically the alkyl chain length of imidazolium (Bu and octyl) and anion species (acrylic anion, Br^–, and PF₆^–). Tunability of wettability resulted in the hydrophilic or hydrophobic property of PILMs. The hydrophilic poly(1-vinyl-3-butylimidazolium acrylate)-based membrane (PILM-1) transported water and intercepted oil, while the hydrophobic poly(1-vinyl-3-octylimidazolium hexafluorophosphate)-based membrane (PILM-5) removed oil and rejected water. The two membranes with opposite wettability showed excellent oil/water separation efficiency (above 99%) in batch processes. Continuous oil/water separation was also achieved by assembling PILM-1 and PILM-5 on the fabricated devices. A T-type device could sep. various oil/water mixtures continuously, and a tank-type device could sep. dispersed oil/water mixtures, with a handling capacity of 46 L within 12 h. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9Application of 915358-85-9).

1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Application of 915358-85-9

1-Vinyl-3-butyl-imidazolium hexafluorophosphate (VBimPF₆) was used as a functional monomer to fabricate an imprinted film onto a glassy carbon electrode modified with gold nanoparticle under the conditions applying 4,4′-dibromobiphenyl (DiBB) as a template, ethylene glycol dimethacrylate (EGDMA) as a cross-linker, and ammonium persulfate and N,N,N’,N’-tetramethylethylenediamine as initiators at room temperature After the fabrication process, the embedded DiBB template was removed to obtain a new electrochem. sensor with high specific recognition sites toward DiBB.

Electrochem. impedance spectroscopy was used to test the sensing performances of this newly developed electrode. The imprinted film exhibited high selectivity and sensitivity in the determination of DiBB.

The formation of stable Langmuir films on the aqueous AgNO₃ subphase of 2-alkyl benzimidazoles(BzCn) with various chain lengths (from C5 to C15) and the layer structures of the transferred films were described. From the surface pressure-area isotherm, the true monolayer could be formed for the short chain derivatives, while multilayer structures for the long ones. All of the Langmuir films could be transferred to solid substrate. The measurement of the UV spectra of the transferred LB films confirmed the coordination between benzimidazole group and Ag(I) ion in the Langmuir films. The effect of the length of alkyl chains on the structure of the transferred LB films was revealed by application of at. force microscopy, FF-IR spectra and XRD measurement. Except for BzC15, a regular layer structure was formed. Characterization of the morphol. points to the formation of the neat LB film for the short derivatives and multilayer structure for BzC15.

Spherical activated carbon modified by polymerized ionic liquid for the removal of ibuprofen from water was written by Xu, Xiao;An, Xiaoning. And the article was included in Journal of Chemical Technology and Biotechnology in 2016.Electric Literature of C9H15F6N2P This article mentions the following:

BACKGROUND: The adsorption capacity of activated carbon has been found to improve through modification with ionic liquids However, ionic liquids tend to sep. from the activated carbon when exposed to water even for a relatively short period. RESULTS: Characterization of spherical activated carbon (SAC) modified with poly(1-vinyl-3-butylimidazolium hexafluorophosphate) (PIL) showed that 1-vinyl-3-butylimidazolium hexafluorophosphate (IL) was adsorbed and polymerized on SAC. Stability studies of PIL-SAC in water demonstrated that it was more stable against IL desorption in water than the non-polymerized IL-SAC. The adsorption data showed that the modification improved the adsorption capacity of SAC at least 2-fold. The results also indicated that although the pH and ionic strength of the solution played a significant role in the adsorption process, there was no significant influence on the adsorption capacity. Moreover, PIL-SAC could be reused at least five times with only minor losses in its adsorption capacity. CONCLUSION : The activated carbon modified with PIL produces a remarkable increase in the ibuprofen adsorption capacity and strongly decreases undesirable desorption of ionic liquids In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9Electric Literature of C9H15F6N2P).

Both the 7-methoxy- [72750-64-2] and 7-ethoxycoumarin dealkylase  [42613-26-3] activities of rat liver microsomes were equally inhibited by cytochrome P 450  [9035-51-2] antagonists with the following order of potency: disulfiram  [97-77-8] > 2-n-octyl benzimidazole  [13060-24-7] > chloramphenicol  [56-75-7] > propranolol  [525-66-6].
