Vapor−liquid equilibria are reported for the following seven binary systems:  ethylene oxide + 2-methylpropane; acetophenone + phenol; cis-1,3-dichloropropene + 1,2-dichloropropane; 1,5-hexadiene + allyl chloride; isopropyl acetate + acetonitrile; vinyl chloride + methyl chloride; and 1,4-butanediol + γ-butyrolactone. The system pressure and temperature were measured at several charge compositions along two or three isotherms for the first six systems and along one isotherm for the seventh system. Equilibrium vapor- and liquid-phase compositions were derived from the PTx data using the Soave equation of state to represent the vapor phase and the Wilson or the Redlich−Kister activity coefficient model to represent the liquid phase. Additional vapor−liquid equilibrium studies were performed on the 1,4-butanediol + γ-butyrolactone system at six compositions by directly analyzing samples that were withdrawn from the equilibrium vapor and liquid phases.

七元系统的汽液平衡：环氧乙烷+ 2-甲基丙烷; 苯乙酮+苯酚; 顺式-1,3-二氯丙烯+ 1,2-二氯丙烷; 1,5-己二烯+烯丙基氯; 乙酸异丙酯+乙腈; 氯乙烯+氯甲烷；和1,4-丁二醇+γ-丁内酯^†

报告了以下七个二元系统的汽液平衡：环氧乙烷+ 2-甲基丙烷; 苯乙酮+苯酚；顺式-1,3-二氯丙烯+ 1,2-二氯丙烷; 1,5-己二烯+烯丙基氯; 乙酸异丙酯+乙腈; 氯乙烯+氯甲烷; 和1，4-丁二醇+γ-丁内酯。在前六个系统的两个或三个等温线以及第七个系统的一个等温线中，在几种装料组成下测量了系统压力和温度。平衡气相和液相组成源自PTx数据使用Soave状态方程表示汽相，使用Wilson或Redlich-Kister活度系数模型表示液相。通过直接分析从平衡气相和液相中提取的样品，在1,4-丁二醇+γ-丁内酯系统上进行了六种组成的附加汽液平衡研究。
