摘　　要：含２－甲基丁烷、甲醇、甲基叔戊基醚体系汽液平衡的测定秦金平钱仁渊云志李志宝史美仁（南京化工大学化工分离研究所，南京２１０００９）关键词２－甲基丁烷甲醇甲基叔戊基醚汽液平衡１前言随着对汽油的质量要求越来越高，对无铅汽油抗爆剂进行的研究发现，醚类物质是...Vapor liquid equilibria (VLE) for following systems were determined by use of a flow still and a static pressurized still: ① 2-methylbutane(1)methanol(2)(55.0℃); ② 2-methylbutane(1)tertamyl methyl ether (TAME)(2)(15.0℃,22.0℃,55.0℃); ③ 2-methylbutane(1)methanol(2)TAME(3)(55.0℃,65.0℃,80.0℃). Data for all binary systems passed the thermodynamic consistency check. Wilson、 NRTL and UNIQUAC models were used to correlate the VLE data determined and their model parameters were obtained. Results show that the NRTL model is the best. The total average vapor composition deviations are 0.0048 for correlation of binary systems and 0.0075 for prediction of ternary system.
