摘要: Abstract Two sulfate-based anion ionic liquids: 1-ethyl-3-methylimidazolium hydrogen sulfate [EMIM]+[HSO4]− and methyl [EMIM]+[MeSO4]− were investigated as entrainer candidates for the separation of binary azeotropic system acetone + methanol. Vapor–liquid equilibria (VLE) acetone + methanol ternary mixtures with these liquids measured by headspace gas chromatography. From experimental VLE data, influence liquid on factors was investigated. The results systems show that two enhance factor calculated compared those hexylpyridinium bis(trifluoromethylsulfonyl)imide [HPY]+[BTI]−, conventional organic entrainers: ethylene glycol water.
