Vapor-liquid equilibrium at 101.3 kPa has been determined for the binary systems of 1,3-dioxolane with cyclohexane, n-heptane and diethyl carbonate. The binary systems of 1,3-dioxolane with cyclohexane and n-heptane exhibit positive deviations from ideal behavior and present azeotropic points with 57% mole 1,3-dioxolane, 341.04 K and 80% mole, 345.6 K respectively. The binary system 1,3-dioxolane-diethyl carbonate behaves almost ideally. The activity coefficients and boiling point of the solution were correlated with its composition by the Redlich-Kister and Wisniak-Tamir equations.
