VAPOR-LIQUID-EQUILIBRIA OF BINARY-MIXTURES CYCLOPENTANE PLUS ISOPROPYL ACETATE, ISOPROPYL ACETATE PLUS HEXANE, AND CYCLOPENTANE PLUS METHYL-METHACRYLATE AT 101.3 KPA

Vapor-liquid equilibria were measured at 101.3 kPa for three binary mi xtures of cyclopentane + isopropyl acetate, isopropyl acetate + hexane , and cyclopentane + methylmethacrylate. The isobaric T-x-y data were reported, including an azeotropic point for the binary mixture of isop ropyl acetate + hexane. Calculations of the nonideality of the vapor p hase were made with the second virial coefficients determined by the T sonopoulos correlation equation. Various activity coefficient models w ere used to correlate the experimental data. Satisfactory results were obtained, and optimally fitted binary parameters are presented.
