The solubility of gestodene in 11 different monosolvents (methanol, ethanol, n-propanol, 1-butanol, isopropanol, isopropyl acetate, ethyl acetate, acetone, butanone, acetonitrile, and water) and a binary solvent of methanol + water was determined at different temperatures ranging from 283.15 to 323.15 K by the shake flask method. The solubility of gestodene in the selected pure solvents and methanol + water binary systems rose with the augmented temperatures. The maximum solubility value of gestodene was recorded in isopropyl acetate and the minimum in water. The modified Apelblat, Van’t Hoff, λh, NRTL, UNIQUAC, and Wilson equations described the solubility data in pure solvents. In addition, the modified Apelblat, Van’t Hoff, λh, Jouyban–Van’t, and Jouyban–Apelblat equations were employed to describe the solubility data in binary solvents. It could be concluded that the Apelblat model provided the best fitting result among the 11 pure and mixed solvents. The research can also provide a theoretical basis for industrial crystallization production.

在 283.15 到 323.15 K 的温度下,孕二烯酮在 11 种纯和二元混合溶剂系统中溶解度的测量和相关性

测定了孕二烯酮在 11 种不同的单溶剂(甲醇、乙醇、正丙醇、1-丁醇、异丙醇、乙酸异丙酯、乙酸乙酯、丙酮、丁酮、乙腈和水)和甲醇 + 水的二元溶剂中的溶解度。通过摇瓶法,温度范围为 283.15 至 323.15 K。孕二烯酮在所选纯溶剂和甲醇 + 水二元体系中的溶解度随着温度的升高而上升。孕二烯酮在乙酸异丙酯中的最大溶解度值和在水中的最小值被记录。修改后的 Apelblat、Van't Hoff、λ h、NRTL、UNIQUAC 和 Wilson 方程描述了纯溶剂中的溶解度数据。此外,修改后的 Apelblat, Van't Hoff, λ h、Jouyban-Van't 和Jouyban-Apelblat 方程用于描述二元溶剂中的溶解度数据。可以得出结论,Apelblat 模型在 11 种纯溶剂和混合溶剂中提供了最佳拟合结果。该研究也可为工业结晶生产提供理论依据。
