ABSTRACT

Vapor - liquid equilibrium (VLE), excess molar enthalpies ( H E ), and excess molar volumes ( V E ) provide means of developing accurate thermodynamic models. In this work, new data of binary mixtures of ethyl acetate, butyl acetate, and 2-butanol are reported. Isothermal VLE data at 350 K were measured by using a circulation still for ethyl acetate + 2-butanol, for 2-butanol + butyl acetate, and for ethyl acetate + butyl acetate. H E was measured at 298 K by using a SETARAM C80 calorimeter equipped with a fl ow mixing cell. V E was measured at 298 K by using an Anton Paar DMA 512P densimeter. Liquid phase activity coe ffi cients of the Wilson model and vapor phase fugacities of the Hayden - O Connell correlation were regressed for a thermodynamic model based on the measured data. Model extrapolation agreed well with literature data. Redlich - Kister equation parameters were regressed by using only the measured V E data.
