Abstract: The physical and chemical properties for 5-chloro-2-pentanone and cyclopropyl methyl ketone, including density, viscosity, molar volume, thermal expansion coefficient, and surface tension, were determined. The vapor-liquid phase equilibrium (VLE) of the binary system of 5-chloro-2-pentanone (1) + cyclopropyl methyl ketone (2) was further determined, and Van Laar equation, Wilson equation, and NRTL equation in Aspen Plus V11 were applied to correlate the experimental data. Moreover, the binary interaction parameters were also obtained by regression. The experimental results were confirmed by a thermodynamic consistency examination. This study not only complements the vapor-liquid phase balance database, but also provides thermodynamic data for the isolation of 5-chloro-2-pentanone and cyclopropyl methyl ketone.
