摘要：The vapor-liquid equilibrium data of four binary systems(acetic acid+p-xylene,methyl acetate+n-propyl acetate,n-propyl acetate+p-xylene and methyl acetate+p-xylene)are measured at 101.33 kPa with Ellis equilibrium still,and then both the NRTL and UNIQUAC models are used in combination with the HOC model for correlating and estimating the vapor-liquid equilibrium of these four binary systems.The estimated binary VLE results using correlated parameters agree well with the measured data except the methyl acetate+p-xylene system which easily causes bumping and liquid rushing out of the sampling tap due to their dramatically different boiling points.The correlation results by NRTL and UNIQUAC models have little difference on the average absolute deviations of temperature and composition of vapor phase,and the results by NRTL model are slightly better than those by UNIQUAC model except for the methyl acetate+n-propyl acetate system,for which the latter gives more accurate correlations.
