【Abstract】 The associating MartinHou equation of state (AMH EOS) is applied to calculate the vaporliquid equilibria, excess enthalpies and excess volumes of binary carboxylic acid + hydrocarbon systems simultaneously. For the isothermal vaporliquid equilibria of 16 carboxylic acid + hydrocarbon systems, the mean relative deviation in pressure is 2.61%, the mean deviation in vapor composition is 0.010?0. For the isobaric vaporliquid equilibria of 21 binary carboxylic acid + hydrocarbon systems, the mean deviation in temperature is 0.73?K, the mean deviation in vapor composition is 0.010?1. For the excess enthalpies of 25 carboxylic acid + hydrocarbon systems, the average deviation is 4.16%. For the 25 sets of excess volume data of 22 carboxylic acid + hydrocarbon systems, the average deviation is 4.48%.更多还原
