摘　　要：用缔合马丁 侯状态方程对二元羧酸+烃体系的汽液平衡、过量焓和过量体积进行了同时计算.对于16个羧酸+烃体系的等温汽液平衡,压强的平均相对偏差为2.61%,汽相摩尔分数的平均偏差为0.0100.对于21个羧酸+烃体系的等压汽液平衡,温度的平均偏差为0.73K,汽相摩尔分数的平均偏差为0.0101.对于25个羧酸+烃体系的过量焓,计算的平均相对偏差为4.16%.对于22个羧酸+烃体系的25套过量体积数据,计算的平均相对偏差为4.48%.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%.
