　　采用乙醇-水-1,3-二甲基咪唑二甲酯磷酸盐（[MMIM]+[DMP]?）体系的汽液相平衡数据回归了NRTL模型的二元交互参数。根据对剩余曲线的分析确定选用[MMIM]+[DMP]?作为萃取剂进行萃取精馏方案的可行性。通过模拟计算得到最佳操作条件：萃取剂进料量为30～40 kg/h，回流比为0.6，原料进料位置为第23块理论板，萃取剂进料位置为第2块理论板，此时塔顶产品浓度可达到99.6%。通过模拟确定的[MMIM]+[DMP]?用于乙醇-水萃取精馏的设计及操作参数为实验研究提供了数据基础，为离子液体工业化的研究提供了理论基础。

Binary interaction parameters of the NRTL model of ethanol-water-1,3-dimethyl-imidazole dimethyl phosphate ([MMIM]+[DMP]?) system were regressed from VLE data. According to the analysis of residue curves,[MMIM]+[DMP]? was selected as the extraction agent in the extractive distillation. The optimum operating conditions were calculated through simulation:the feed of the extraction agent was 30 to 40 kg/h,reflux ratio was 0.6,the location of the raw material feed was the 23th theoretical plate,the extraction agent feed location was the 2nd theoretical plate,and the distillate product concentrations was up to 99.6%. The design and operating parameters of [MMIM]+[DMP]? for ethanol - water extractive distillation were determined through simulation,providing a theoretical basis for the commercial use of ionic liquids.
