Vapor-liquid equilibrium at 92 kPa has been determined for the binary systems 2,2’-oxybis[propane] (diisopropyl ether) + propanol and methyl ethanoate + 2,2’-oxybis[propane]. Both systems exhibit moderate positive deviations from ideal behavior; the system methyl ethanoate + 2,2’-oxybis(propane] forms an azeotrope that boils at 360.05 K and contains 79.3 mol % methyl ethanoate. The activity coefficients and boiling point of the solution were correlated with its composition by the Redlich-Kister, Wohl, Wilson, UNIQUAC, NRTL, and Wisniak-Tamir equations.
