The isobaric vapor–liquid equilibrium (VLE) data for three binary systems of 1-(methoxymethoxy)-propane and ethanol, 1-(ethoxymethoxy)-propane and 1-butanol, methoxy(methoxymethoxy)methane and 1-propanol at 101.33 kPa were measured using an improved Rose still. Three minimum boiling azeotropes were found for three binary systems containing ethanol, 1-butanol, and 1-propanol for which the azeotropic temperature and composition are 349.35 K and 70.95 mol % (ethanol), 384.02 K and 36.02 mol % (1-butanol), 368.68 K and 69.26 mol % (1-propanol), at 101.33 kPa, respectively. The VLE measurements were correlated by the Van Laar, Wilson, and nonrandom two-liquid models, and the results showed that the measurements had a good correlation by using thethree models for the three binary systems, respectively. The measurements of these three binary systems were thermodynamic as checked by the Herington semiempirical method.
