The correlation of solubility and solution thermodynamics of 1,2- diphenylethane in different pure solvents has been studied. The mole fraction solubilities of 1, 2-diphenylethane in acetone, chloroform, dichloromethane, and ethanol increase with temperature. The mole fraction solubility in acetone, chloroform and dichloromethaneare much higher than that in ethanol and the mole fraction solubilities in chloroform and dichloromethane are higher than that in acetone. The solubility data were well correlated by the modified Apelblat,the semi-empirical Buchowski-Ksiazczak λh equation, and the ideal solution equation.The enthalpy, entropy and apparent free Gibbs energy of solution in different solvents were calculated. The dissolving process of 1,2-diphenylethane was endothermic, entropy-driving and not spontaneous.

1，2-二苯乙烷在不同纯溶剂中的溶解度和溶液热力学的测定及其相关性

研究了1,2-二苯乙烷在不同纯溶剂中的溶解度与溶液热力学的相关性。1，2-二苯乙烷在丙酮，氯仿，二氯甲烷和乙醇中的摩尔分数溶解度随温度而增加。在丙酮，氯仿和二氯甲烷中的摩尔分数溶解度比在乙醇中的摩尔分数溶解度高得多，并且在氯仿和二氯甲烷中的摩尔分数溶解度比在丙酮中的摩尔分数溶解度高。通过改进的Apelblat，半经验Buchowski-Ksiazczakλh方程和理想溶液方程，很好地关联了溶解度数据。计算了在不同溶剂中溶液的焓，熵和表观自由吉布斯能。1,2-二苯乙烷的溶解过程是吸热的，熵驱动的且不是自发的。
