Densities and Excess Molar Volumes of the Ternary System (1,4-Dioxane + 2-Propanol + 1,1,2,2-Tetrachloroethane) at T = 288.15–318.15 K and at Atmospheric Pressure: Experimental Measurements and Prigogine–Flory–Patterson Modeling

Excess molar volumes for 1,4-dioxane + 2-propanol + 1,1,2,2-tetrachloroethane ternary mixture and for the constituent binaries were determined from density measurements over the entire composition range at four temperatures between 288.15 and 318.15 K and at atmospheric pressure. The ether-containing binary mixtures present a positive excess molar volume, VE, with alkanol and negative VE values with chloroalkane over the whole composition and working temperature ranges. As the temperature increases, the VE magnitude increases for 1,4-dioxane + 2-propanol, whereas it decreases for 1,4-dioxane + 1,1,2,2-tetrachloroethane. For 2-propanol + 1,1,2,2-tetrachloroethane mixture, sigmoidal–VE curves are observed and the VE increases as the temperature increases. Sigmoidal–V123E curves are observed also for 1,4-dioxane + 2-propanol + 1,1,2,2-tetrachloroethane ternary mixture. The equations of Redlich–Kister and Cibulka were used to fit the experimental excess molar volume data, for the investigated binary and terna...
