Abstract
Phase equilibria are reported for the following four systems: 1,2-dichloroethane (CASRN 107-06-2) + trans-1,2-dichloroethylene (CASRN 156-60-5) at 30 °C and 80 °C; 1-octene (CASRN 111-66-0) + 2-methyl thiophene (CASRN 554-14-3) at 100 °C and 140 °C; 2-ethyl thiophene (CASRN 872-55-9) + 2,2,4-trimethylpentane (CASRN 540-84-1) at 100 °C and 140 °C; cyclopropanecarbonitrile (CASRN 5500-21-0) + water (CASRN 7732-18-5) at 100 °C and 135 °C. 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 NRTL activity coefficient model to represent the liquid phase. Two liquid phases are present with the cyclopropanecarbonitrile + water system at 100 °C. Vapor−liquid−liquid equilibrium data were measured at this condition. Multiple samples were withdrawn and analyzed from each equilibrium phase. A...
