1,2-环己二醇溶解度的测定及关联

MEASUREMENT AND CORRELATION OF SOLUBILITIES OF 1,2-CYCLOHEXANEDIOL

采用激光监视技术测定了 1,2 环己二醇在乙酸甲酯、乙酸乙酯、乙酸丙酯、乙酸丁酯、丙烯酸甲酯、丙烯酸乙酯、甲基丙基酮、乙酰乙酸乙酯和水中的溶解度 ,并用UNIFAC模型进行了关联 ,其溶解度预测值与实测值吻合良好 .

By using laser monitoring technique, the solubilities of 1,2-cyclohexanediol in different solvents, such as methyl acetate, ethyl acetate, propyl acetate, butyl acetate, methyl acrylate, ethyl acrylate, 2-pentanone, ethyl acetoacetate and water, were measured in larger temperature intervals by the synthetic method. A solubility UNIFAC model was proposed. The model was verified with experimental data in ternary systems of both water + ethyl acetate-1,2-cyclohexanediol and water + butyl acetate + 1,2-cyclohexanediol, and the solubilities were calculated by the model and agreed with experimental data.
