those consisting of tetrafluoroborate, alkylsulfate, alkylsulfonate, carboxylate, or phosphate anions are hydrophilic and are completely dissolved in water. Dupont and coworkers first reported stable hydrophobic imidazolium salt, 1-butyl-3-methylimidazolium hexafluorophosphate ([C4mim][PF6]) in 1996. Since...
Copolymerization of aniline and propylene oxide was carried out galvanostatically in an ionic liquid 1-butyl-3-methylimidazolium hydrogen sulfate ([bmim]HSO_4). 采用恒电流电解法,在1-丁基-3-甲基咪唑硫酸氢盐([bmi m] HSO4)离子液体中合成了苯胺与环氧丙烷共聚物(PAN-PPO) 。2...
The solubility of 1-butyl-3-methylimidazolium octylsulfate, [BMIM][OcSO 4 ], has been determined in hydrocarbon ( n -hexane, n -heptane, n -octane or n -decane) solutions and alcohol (methanol, 1-butanol, 1-hexanol, 1-octanol or 1-decanol) solutions. Densities and excess molar volumes...
