Abstract

Vapor-liquid equilibrium at 94 kPa has been determined for the binary systems 4-methyl-2-penatanone (methyl isobutyl ketone)+octane and hexane+1,3-dioxolane. The system 4-methyl-2-pentanone+octane behaves like a regular solution, with moderate deviations from ideal behavior, and presents an azeotrope that boils at 384.05 K and contains 70 mole % ketone. The system hexane+1,3-dioxolane deviates strongly from ideal behavior and has an azeotrope that boils at 332.76 K and contains 55 mole % hexane. The activity coefficients and boiling points of both binary systems were well correlated with its composition by the Redlich-Kister, Wohl, Wilson, UNIQUAC, NRTL and Wisniak-Tamir equations.
