Experimental vapor liquid equilibrium (VLE) data for binary systems of 1-(ethoxymethoxy)-2-methylpropane (EMMP) with isobutyl alcohol and 1-butanol at 101.33 kPa was measured. The measurements of saturated vapor pressure for EMMP were also measured. The experiment was performed by an improved Rose still. A minimum boiling azeotrope was found about the binary system containing 1-butanol for which the azeotropic temperature and composition are 389.64 K and 75.92 mol% (1-butanol) at 101.33 kPa. The VLE measurements were correlated by the Wilson, nonrandom two-liquid, and universal quasichemical models for which the results showed that the measurements had a good correlation by using three models about two binary systems, respectively. The thermodynamic consistency of the VLE measurements was checked by the traditional area test and the direct test methods.
