Density, Viscosity, and Vapor-Liquid Equilibrium Data for the Binary Mixture at Atmosphere Pressure: Cyclopropyl Methyl Ketone+2-Acetylbutyrolactone, Cyclopropyl Methyl Ketone+5-Chloro-2-pentanone

摘要

The density and viscosity of the cyclopropyl methyl ketone (CPMK) + 2-acetylbutyrolactone (ABL) and CPMK + 5-chloro-2-pentanone (CPE) binary mixtures were measured at the temperature range of 303.15 to 333.15 K at atmospheric pressure (about 101.325 +/- 0.3 kPa). The excess molar volume and viscosity deviation were calculated based on the experimental data of density and viscosity, and they could be accurately described by the Redlich-Kister equation. In addition, the vapor-liquid equilibrium (VLE) data for the CPMK-ABL binary system were measured at atmospheric pressure. It was shown that there is no azeotrope in this binary mixture. The VLE data were correlated with NRTL, Wilson, and UNIQUAC models and the interaction parameters obtained were reported. The prediction accuracies of these models were about the same.
