将Watson公式推广应用于推算共沸溶液的汽化热,优化得到了醇-烃体系的Watson公式中的参数n为0.14。用共沸点法求得了Wilson能量配偶参数,推算了14个二元体系和5个三元体系在不同温度或压力下的汽液平衡数据,获得了较为满意的结果。
The Watson formula was extended to calculate the heat of vaporization of the azeotropic solution, and the parameter n in the Watson formula of the alcohol-hydrocarbon system was optimized to be 0.14. The parameters of Wilson energy spline were obtained by azeotropic boiling point method, and the vapor-liquid equilibrium data of 14 binary systems and 5 ternary systems at different temperatures or pressures were calculated. The satisfactory results were obtained.
