Experiment of Molar Excess Enthalpies for Water + 1,2- Ethanediol and some Thermodynamic Properties Calculation

摘要：

This paper reports experimental molar excess enthalpies HE of the binary system water + 1,2-ethanediol. Measurements have been carried out at 298.15, 313.15, 323.15K temperatures and ambient pressure, using a Calvet Setaram BT2.15 microcalorimeter. The results were fitted by Redlich-Kister equation. From R-K fitting equation, the partial excess enthalpies at different temperatures have been calculated, and the expression of excess heat capacities has been derived.
