报告了以下五个体系在两个温度下的汽液平衡：2-（2-（己氧基）乙氧基）乙醇+1，2-乙烷; 2-（己氧基）乙醇+1，2-丙二醇;丙酮氰醇+丙酮;丙酮氰醇+氰化氢;丙基异丁烷+丁烷。系统压力和温度是在几种装料组成下沿沿着给定的等温线测量的。平衡的汽相和液相组成，来自从测量的PTx数据，使用Soave状态方程来表示气相和威尔逊或货车Laar活度系数模型来表示液相。氧在环氧丙烷中的溶解度、氮在环氧丙烷中的溶解度和甲烷在二氯甲烷中的溶解度已经在三种压力下在两种或三种温度中的每一种下测量。
Vapor−liquid equilibria are reported for the following five systems at two temperatures each: 2-(2-(hexyloxy)ethoxy)ethanol + 1,2-ethanediol; 2-(hexyloxy)ethanol + 1,2-propanediol; acetone cyanohydrin + acetone; acetone cyanohydrin + hydrogen cyanide; propyl mercaptan + butane. The system pressure and temperature were measured at several charge compositions along a given isotherm for each system. Equilibrium vapor- and liquid-phase compositions were derived from the measured PTx data using the Soave equation of state to represent the vapor phase and the Wilson or the van Laar activity coefficient model to represent the liquid phase. The solubility of oxygen in propylene oxide, nitrogen in propylene oxide, and methane in dichloromethane has been measured at three pressures at each of two or three temperatures.
