摘要
采用两步法合成了三种离子液体[CH2CH2OHMIM][BF4]、[CH2COOHMIM][BF4]、[CH2COOCH3MIM][BF4],并用新的双循环沸点仪测定了乙醇-水-ILs的汽液平衡。实验表明:三种离子液体均能消除乙醇-水的共沸点。
Three different task-specific ionic liquids - [CH2CH2OHMIM] [BF4], [CH2COOHMIM] [BF4], [CH2COOCH3MIM][BF4] were synthesized . A new double circle ebulliometer was used to measure the data of vapor-liquid equilibrium（VLE） of ethanol-water system （pressure at 101.3kPa,mass value of ILs as 30% respectively）. The experiments proved that the three different ionic liquids could withdraw the azeotropic point of ethanol-water systerm.
