ABSTRACT

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 was measured which was performed by an improved Rose still. Three minimum boiling azeotropes were found about three binary systems containing ethanol, 1-butanol and 1-propanol which these azeotropic temperature and composition are 349.35 K & 70.95 mole%(ethanol), 384.02 K & 36.02 mole%(1-butanol), 368.68 K & 69.26 mole%(1-propanol), at 101.33 kPa, respectively . The VLE measurements were correlated by the Van Laar, Wilson and NRTL models for which the results showed that the measurements had a good correlation by using three models about three binary systems, respectively. These measurements of three binary systems were thermodynamic consistency which has been checked by the Herington semi-empirical method.
