Synthesis and roperties of seven ionic liquids containing 1-methyl-3-octylimidazolium or 1-butyl-4-methylpyridinium cations was written by Papaiconomou, Nicolas;Yakelis, Neal;Salminen, Justin;Bergman, Robert;Prausnitz, John M.. And the article was included in Journal of Chemical & Engineering Data in 2006.Category: pyridine-derivatives This article mentions the following:
Syntheses are reported for ionic liquids containing 1-methyl-3-octylimidazolium or 1-butyl-4-methylpyridinium cations and trifluoromethyl sulfonate, dicyanamide, bis(trifluoromethylsulfonyl)imide, or nonafluorobutyl sulfonate anions. Densities, m.ps., glass-transition temperatures, solubilities in water, and polarities have been measured. Ionic liquids containing pyridinium cations exhibit higher m.ps., lower solubility in water, and higher polarity than those containing imidazolium cations. In the experiment, the researchers used many compounds, for example, 1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6Category: pyridine-derivatives).
1-Butyl-4-methylpyridin-1-ium bromide (cas: 65350-59-6) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Category: pyridine-derivatives
