Isobaric Vapor–Liquid Equilibrium for 2-Butanone + Ethanol System Containing Different Ionic Liquids at 101.3 kPa

18-Jan-2018 | Wenxiu Li; Xue Chen; Haiying Yin; Linhao Li; Tao Zhang, Journal of Chemical & Engineering Data, 2018

In this work, ionic liquids (ILs) were selected as extractive distillation entrainers to separate the 2-butanone + ethanol binary azeotropic mixture because of their remarkable molecular designability, high selectivity, low volatility, and other excellent characteristics. The isobaric ...
