Abstract

The excess molar enthalpies $H_m^E$ at T=298.15 K and p=101.3 kPa of ternary system {1,2-dichloropropane (1,2-DCP) + 1,3-dioxolane+ 1,4-dioxane} were predicted by using the binary contribution model of $Radojkovi{\check{c}}$ with correlated sub-binary Redlich-Kister parameters. Excess partial molar enthalpies ${\bar{H}}_i^E$ were also calculated for the binary systems {1,2-dichloropropane + 1,3-dioxolane}, {1,2-dichloropropane + 1,4-dioxane} and {1,3-dioxolane + 1,4-dioxane} using adjustable parameters of Redlich-Kister equation. By extrapolation of excess partial molar enthalpies to infinite dilution, limiting excess partial molar enthalpies ${\bar{H}}_i^{E,{\infty}}$ of each component were also obtained. The ternary excess molar enthalpies excess partial molar enthalpies of these sub-binary systems have been calculated by using our previously reported results.
