The excess molar enthalpies, volumes and deviations in refractive indices for the binary systems of 1,2-dichloropropane (1,2-DCP) + 2-alkoxyethanols. The 2-alkoxyethanols selected in this work were: 2-isopropoxyethanol (C-C, single bond), 2-allyloxyethanol (C=C, double bond) and 2-phenoxyethanol (C6H5-, phenyl group). These experimental data (HE, VE and ΔnD) were measured over the whole composition range at T=298.15 K and 101.3 kPa using an isothermal calorimeter, densimeter and refractometer, respectively. The experimental results of HE, VE and ΔnD were fitted to modified Redlich-Kister equation to present the composition dependence of excess properties. The HE values were also correlated using thermodynamic models (Wilson, NRTL, and UNIQUAC). |
