By using the method of dynamic laser, the solubilities of succinic acid and glutaric acid in ε-caprolactone + acetic acid mixtures and ε-caprolactone + cyclohexanone mixtures were determined under atmospheric pressure. The experimental temperature ranged from 293.35 to 340.65 K, and the mass fraction of ε-caprolactone in the solvent mixtures ranged from 0.0 to 1.0, respectively. It was found that with the increase of the temperature at constant concentration, the measured solubilities of succinic acid and glutaric acid in ε-caprolactone + acetic acid mixtures and ε-caprolactone + cyclohexanone mixtures would increase. Moreover, when the mass fraction of ε-caprolactone in ε-caprolactone + acetic acid mixtures increases at the same temperature, the measured solubilities of succinic acid and glutaric acid would decrease. However, it would increase as the mass fraction of ε-caprolactone increases for the system of ε-caprolactone + cyclohexanone at the same temperature. The experimental data were correlated by using the modified nonrandom two liquid activity coefficient model. The maximum value of average relative deviation was 1.50%.

琥珀酸和戊二酸在ε-己内酯+乙酸混合物和ε-己内酯+环己酮混合物中的溶解度的测量和相关性
采用动态激光法，在大气压下测定琥珀酸和戊二酸在ε-己内酯+乙酸混合物和ε-己内酯+环己酮混合物中的溶解度。实验温度为293.35至340.65 K，混合溶剂中ε-己内酯的质量分数为0.0至1.0。发现随着恒定浓度下温度的升高，所测量的琥珀酸和戊二酸在ε-己内酯+乙酸混合物和ε-己内酯+环己酮混合物中的溶解度将增加。此外，当ε-己内酯+乙酸混合物中的ε-己内酯的质量分数在相同温度下增加时，所测得的琥珀酸和戊二酸的溶解度将降低。然而，在相同温度下，ε-己内酯+环己酮体系随ε-己内酯质量分数的增加而增加。利用改进的非随机两液体活度系数模型对实验数据进行关联。平均相对偏差的最大值为1.50％。
