Quantitative Analysis of Conductivity and Viscosity of Ionic Liquids in Terms of Their Relaxation Times was written by Yamaguchi, Tsuyoshi;Nakahara, Eiichiro;Koda, Shinobu. And the article was included in Journal of Physical Chemistry B in 2014.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:
The frequency-dependent viscosity and conductivity of various ionic liquids were measured exptl., and their mean relaxation times were determined The relaxation times of the viscosity and conductivity were approx. correlated with their resp. zero-frequency limiting values. The Walden products, however, appeared to have no correlation with the ratio of the relaxation time of viscosity to that of conductivity in general. When the alkyl chain of the cation is as short as Bu, more viscous ionic liquids tend to show larger difference between two relaxation times and larger Walden products. Lengthening the alkyl chain of the cation decreases the Walden product while slightly increasing the relaxation time ratio, which was elucidated in terms of the decrease in the high-frequency shear modulus. In addition, the contribution of the mesoscopic structure to viscosity was suggested in the case of the ionic liquid with the longest alkyl chain studied in this work, 1-dodecyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Application In Synthesis 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 derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide
