ABSTRACT

Vapor-liquid-liquid equilibrium data for the binary systems 2-methyl-1,3-dioxolane + water and 2,4- dimethyl-1,3-dioxolane + water were collected by using a modified Othmer still vessel at 1 atm of pressure. The UNIQUAC equation of state was fitted to the experimental T-x-x-y data to generate the coefficients of the binary interaction parameters for each system. Vapor pressures for pure 2,4-dimethyl-1,3-dioxolane and 2-methyl-1,3-dioxolane were also measured and used to calculate the constants in Antoine s equation and pure component parameters for each dioxolane. The enthalpy of vaporization calculated from vapor pressure data via the Clausius-Clapeyron equation was in good agreement with the literature value.
