Description
Summary: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.
