ABSTRACT

This paper presents densities and excess molar enthalpies of the binary mixtures dimethyl carbonate with alkanes from C6 to C10 at several temperatures, and isobaric vapor-liquid equilibrium (VLE) data at 101.3 kPa for dimethyl carbonate with nonane and decane are shown too. Correlations of the activity coefficients and reduced excess Gibbs energy using Wilson, NRTL, and UNIQUAC equations were good for all the binary mixtures. The ASOG and UNIFAC methods were used to predict the VLE binary mixtures. The best predictive results were yielded by ASOG for the binary dimethyl carbonate with nonane and by UNIFAC for dimethyl carbonate with decane.
