The ionic liquid 1-butyl-3-methylimidazolium dibutylphosphate ([BMIM][DBP]) was prepared and vapor pressure for three binary systems composed of [BMIM][DBP]and water
methanol or ethanol were measured at different temperature and mole fraction with static method
the data was correlated with NRTL activity coefficient model. The results indicate that the binary solutions are all negative deviation from the Roualt’s Law
which make them to be suitable as candidates for working pairs in industrial applications of absorption heat pumps. Meanwhile the experimental data can be well correlated by NRTL equations with the average relative deviations (ARD) of 2.37%
