The T–x–y data for binary mixtures composed of methyl acetate + (1-chloropentane or 1-chlorohexane) and ethyl acetate + (1-chloropentane or 1-chlorohexane) have been measured ebulliometrically at 101.32 kPa using a dynamic method. In thermodynamic calculations using these data, the vapor phase was considered to be non-ideal, and the four systems studied exhibit positive deviations from Raoult’s law. The activity coefficients and vapor phase compositions have been compared with those predicted by using UNIFAC and ASOG models.
