tert‐Butanol (TBA) and water form an azeotrope at atmospheric pressure. Therefore, extractive distillation was adopted to separate the azeotropic mixture. As a new kind of solvent, the ionic liquids (ILs) 1,3‐dimethylimidazolium dimethylphosphate ([MMIM][DMP]) and 1‐ethyl‐3‐methylimidazolium diethylphosphate ([EMIM][DEP]) were chosen to break the azeotropic point in extractive distillation.

大气压力下叔丁醇+水+离子液体的等压汽液平衡

叔丁醇（TBA）和水在大气压下形成共沸物。因此，采用萃取蒸馏分离共沸混合物。作为一种新型溶剂，选择了离子液体（IL）1,3-二甲基咪唑二甲基磷酸酯（[MMIM] [DMP]）和1-乙基-3-甲基咪唑二乙基磷酸酯（[EMIM] [DEP]）来破坏共沸物萃取蒸馏中的点。
