DENSITIES AND DERIVED PROPERTIES OF WATER, 1,4-DIOXANE AND DIMETHYL SULFOXIDE BINARY AND TERNARY SYSTEMS AT TEMPERATURES FROM 293.15 K TO 313.15 K

摘要

Excess molar volumes (V~E ) and excess partial molar volumes ( V_i~E ) of the binary systems: water+l,4-dioxane, 1,4-rndioxane+dimethyl sulfoxide, water+dimethyl sulfoxide and of the corresponding ternary system water+1,4-dioxane+dimethyl sulfoxide have been evaluated from experimental density at five temperatures ranging from 293.15 K to 313.15 K. For all binary mixtures, the experimental data were correlated with Redlich-Kister's equation. For ternary system, the excess molar volume was estimated by correlative and predictive (symmetrical and asymmetrical) methods and the results were compared. The calculated functions have been used to explain the intermolecular interactions between the mixing components.
