用重量法测定了硬脂酸在乙醇、甲醇、乙酸乙酯和丙酮中的溶解度，温度范围为301 ~ 313k。硬脂酸在乙酸乙酯中的溶解度最高，其次是乙醇、丙酮和甲醇。所有实验数据均采用非理想解模型，即修正的Apelblat方程和Buchowski方程进行关联。计算结果与实验数据吻合较好。
The solubility of stearic acid in ethanol, methanol, ethyl acetate, and acetone has been measured gravimetrically at various temperatures ranging from 301 to 313 K at atmospheric condition. The solubility of stearic acid in ethyl acetate was found to be the highest, followed by ethanol, acetone and methanol. All experimental data were correlated using non-ideal solution models, namely, the modified Apelblat and the Buchowski equations. The calculated results agreed well with the experimental data.
