Measurement and explaning of volumetric properties for ternary system 1,3-Dichloro-2 propanol+ 1-Hexanol + Diethyl malonate and corresponding binary systems at different temperatures and ambient pressure

By using the experimental density data, some volumetric properties including excess molar volume, partial molar volume, partial molar volume in infinite dilution for ternary system 1,3 dichloro 2-propanol+ 1- Hexanol + dimethyl malonate and their corresponding binary solutions at temperatures 293.15-313.15 K have been evaluated. Redlich-Kister equation has been applied to fitting the excess molar volumes data and then by applying derived parameters, partial molar volumes are appraised. Nagata-Tamura equation, Cibulka and Sing equation are applied to excess molar volumes of ternary system. Results showed that all values of excess molar volumes for binary and ternary considered systems were positive. Based on the results of measurements, different possible interactions which are present are discussed.
