Vapor pressure, vapor-liquid equilibrium, and excess enthalpy data for compounds and binary subsystems of the chlorohydrin process for propylene oxide production

Vapor-liquid equilibrium (VLE), excess enthalpy (H-E), and vapor pressure ( P-i(S)) data for eight binary systems containing cis-1-chloropropene, trans -1-chloropropene, 1,2-dichloropropane, 1,2-propanediol, 1,2-propylene glyco l diacetate, propylene oxide, and water are presented in a temperature rang e from 276 to 368 K. The VLE and vapor pressure data were obtained by means of a computer-controlled static apparatus, and the heat of mixing data wer e measured using an isothermal flow calorimeter. Temperature-dependent NRTL interaction parameters were regressed by a simultaneous correlation of the experimental VLE and H-E data. These parameters are required for a proper simulation of the different separation steps in the chlorohydrin process fo r the production of propylene oxide.
