摘要 利用缔合马丁 侯状态方程(AMHEOS)对二元醇+烃体系、羧酸+烃体系的汽液平衡、超额焓等热力学性质的同时计算所获得的相应体系的二元交互作用参数QEN,采用两种方法,用AMHEOS对15个二元醇+烃体系、7个二元羧酸+烃体系的超额Gibbs自由能进行了预测.预测结果与实验结果相比,方法一的平均相对偏差为2.42%,方法二的平均相对偏差为2.46%. Using the binary interaction parameter QEN obtained from simultaneous calculation of thermodynamic properties such as vapor-liquid equilibria and excess enthalpy etcetera of binary alcohol + hydrocarbon systems and carboxylic acid + hydrocarbon systems by associated Martin-Hou equation of state, the excess Gibbs free energies of 15 binary alcohol + hydrocarbon systems and 7 binary carboxylic acid + hydrocarbon systems are predicted by two methods. Compared with the corresponding experimental results, the average relative deviation of the predicted results for these systems by method one is 2.42%, the corresponding average relative deviation by method two is 2.46%.
