Vapor-Liquid Equilibrium for Methanol-Acetonitrile-1-Butyl-3-Methylimidazolium Tetrafluoroborate Ternary System
摘要
Abstract
Isobaric vapor-liquid equilibrium for methanol-acetonitrile-1-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF4) ternary system was measured at 101.32 kPa using CE-2 Othmer vapor-liquid equilibrium still. UNIFAC equations were used to correlate the experimental data. The experimental results indicated that the vapor-liquid equilibrium curves of the methanol-acetonitrile-. [bmim]BF4 system deviated from that of the [bmim]BF4-free system and the deviation increased with the increase of the [bmim]BF4 dosage. The ionic liquid [bmim]BF4 exhibited notable salt-out effect which could enhance the relative volatility. When the mole fraction of [bmim]BF4 amounted to 10%, the azeotropic point disappeared. UNIFAC equation can be used to predict the equilibrium of methanol-acetonitrile- [bmim]BF4 system.关键词
