用浊点法、定组成变温法、平衡釜法３种实验方法，分别测定了糠醛－水二元物系在２０～９０℃之间、乙酸乙酯－水二元系在２５～６０℃之间以及乙酸甲酯－水在２５～５０℃之间不同温度下三组二元系互溶度数据。用平衡釜法同时测定了二氯甲烷－水二元物系在１５～４０℃之间的互溶度数据。分析了３种自制实验装置的结构对测定准确性的影响。比较了３种实验方法在结果准确性、方法的难易程度以及对不同物系的适用性方面的优缺点。
The turbidity point method, the composition of the variable temperature method, equilibrium kettle three kinds of experimental methods, were measured furfural - water binary system between 20 ~ 90 ℃, ethyl acetate - water binary system at 25 ~ 60 ℃ And methyl acetate - water at different temperatures between 25 ~ 50 ℃ three binary system mutual solubility data. The equilibria data of dichloromethane - water binary system at 15 ~ 40 ℃ were simultaneously determined by the equilibrium method. The effects of the structures of three homemade devices on the accuracy of the assay were analyzed. The advantages and disadvantages of the three experimental methods in terms of the accuracy of the results, the ease of the method, and the applicability to different systems were compared.
