Structural effect on the vapor-liquid equilibrium of toluene-ionic liquid systems was written by Yu, Gangqiang;Jiang, Yifan;Cheng, Jun;Lei, Zhigang. And the article was included in Chemical Engineering Science in 2019.Quality Control of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:
The vapor-liquid equilibrium (VLE) of toluene-ionic liquid (IL) from short- to long-chain imidazolium-based ILs (i.e., [C4MIM]+, [C8MIM]+, [C10MIM]+, and [C12MIM]+) with various anions (i.e., [BF4]–, [PF6]–, and [Tf2N]–) was first measured under wide concentration and temperature ranges. These thermodn. data are of great significance for an in-depth understanding with respect to capturing condensable gases with ILs. The UNIFAC-Lei model was applied to describe the VLE and successfully extended from short- to long-chain imidazolium-based ILs. For the ILs with relatively short alkyl side-chains on cations (e.g., [C4MIM]+ and [C8MIM]+), the vapor pressure depends on the types of both anions and cations, while for the ILs with long alkyl side chains on cations (e.g., [C10MIM]+ and [C12MIM]+), the vapor pressure is mainly dependent on the type of cations. Moreover, the COSMO-RS model and quantum chem. calculations were used together to provide microscopic insights into the effect of IL structures on the VLE of toluene-IL systems. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Quality Control of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).
3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) 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. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Quality Control of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide
