Abstract: The solid-liquid equilibria of adduct-forming systems were predicted by chemical-physical models based on the work of Stoicos and Eckert. The equilibrium adductive constants in the models were measured by gas chromatogra-phy for six binary systems of tetrachloromethane/p-xylene, tetrachloromethane/pseudocumene, phenol/aniline, meta-methylphenol/aniline, ortho-methyl-phenol/aniline, ortho-chlorophenol/aniline. The physical interactions in the models were described by ideal solution theory, regular solution theory and UNIFAC model. The comparisons of the predicted results with the phase diagrams in the literatures show that this approach is indeed excellent.

摘要: 在Stoicos和Eckert工作的基础上,用实测的加合常数,结合正规溶液化学模型、UNIFACA化学模型、理想化学模型对有加合物生成体系的固液平衡预测作了研究.测定了四氯化碳/对二甲苯、四氯化碳/偏三甲苯、苯胺/苯酚、苯胺/间甲酚、苯胺/邻甲酚及苯胺/邻氯酚6个体系的加合常数,并据此计算了这些体系的固液平衡,与文献相图比较,结果令人满意.
