离子液体对乙腈-水共沸物系汽液平衡的影响
Effect of ionic liquid on the vapor-liquid equilibrium of acetonitrile-water
摘要
Abstract
The ionic liquid 1-butyl-3-methylimidazolium chloride（Bmin）was selected as the solvent to separate azeotropic mixture of acetonitrile-water.Isobaric vapor-liquid equilibrium data for acetonitrile-water system containing ionic liquid Bmin were measured at 0.101 MPa.The azeotropic point of acetonitrile-water can be eliminated by adding ionic liquid Bmin,and relative volatility of acetonitrile to water can be increased.By using the modified Furter equation of the VLE for mixed-solvent electrolyte systems,the parameters of salt-effection of ionic liquid Bmin to acetonitrile-water system was correlated.关键词
