摘　　要：采用改进的 Rose釜测定乙醇 +N-甲基哌嗪和异丙醇 +N-甲基哌嗪两个二元体系在 10 1.3k Pa压力下的汽液平衡数据 ,用折光指数法确定汽、液相组成 .采用 UNIQUAC活度系数模型关联实验数据 。The isobaric vapor liquid equilibrium (VLE) data for the binary mixtures of ethanol + N methylpiperazine and isopropanol + N methylpiperazine were measured at 101.3 kPa by using a modified Rose still. The vapor liquid compositions of the mixtures were analyzed by refractometry. The experimental VLE data were correlated by the UNIQUAC liquid phase activity coefficient model with satisfactory results.
