摘要/描述

A new stainless steel apparatus for measuring azeotropic points of binary as well as multicomponent systems at elevated pressures has been developed. The azeotropic temperatures and compositions of six binary systems composed of cyclohexane, 2-propanol, ethyl acetate, and butanone were determined at elevated pressures, correlated by empirical equations with pressure, and predicted by the UNIFAC group contribution method. The calculations demonstrate that the correlated data are in good agreement with experimental values.
