In this work, the solubilities of adipic acid and succinic acid in glutaric acid + cyclohexanone and glutaric acid + acetic acid mixtures were measured respectively by using the laser dynamic method under atmospheric pressure, in which the temperature ranged from 296.15 to 340.85 K and the mass fraction of glutaric acid in the binary solvent mixtures ranged from 0.00 to 0.30. The effects of glutaric acid on solubility of adipic acid and succinic acid have been discussed. It is found that the effects of glutaric acid on the solubility of adipic acid and succinic acid were negative and that with the increasing mass fraction of glutaric acid in the mixtures the solubilities of adipic acid and succinic acid would decrease. With the gradual increase of temperature, the measured solubility of adipic acid and succinic acid in glutaric acid + cyclohexanone and glutaric acid + acetic acid mixtures would increase at the constant proportion of solvent mixtures. Then the experimental data were well-correlated by the modified Apelblat equation and the modified nonrandom two-liquid (NRTL) activity coefficient models, in which the average relative deviation (ARD) were less than 2.50%, and the values of the solubility calculated showed good agreement with the experimental observation. The interaction parameters of AA and GA and SA and GA were determined first in this work.

己二酸和琥珀酸在戊二酸+环己酮和戊二酸+乙酸混合物中的溶解度的测量和相关性

这项工作中，使用大气压下的激光动力学方法分别测量了己二酸和琥珀酸在戊二酸+环己酮和戊二酸+乙酸混合物中的溶解度，温度范围为296.15至340.85 K，质量二元溶剂混合物中戊二酸的馏分范围为0.00至0.30。讨论了戊二酸对己二酸和琥珀酸溶解度的影响。发现戊二酸对己二酸和琥珀酸的溶解度的影响为负，并且随着混合物中戊二酸质量分数的增加，己二酸和琥珀酸的溶解度将降低。随着温度的逐渐升高，己二酸和琥珀酸在戊二酸+环己酮和戊二酸+乙酸混合物中测得的溶解度将在溶剂混合物的恒定比例下增加。然后通过改进的Apelblat方程和改进的非随机二液（NRTL）活度系数模型对实验数据进行很好的关联，其中平均相对偏差（ARD）小于2.50％，并且计算出的溶解度值显示与实验观察吻合良好。这项工作首先确定了AA和GA以及SA和GA的相互作用参数。然后通过改进的Apelblat方程和改进的非随机二液（NRTL）活度系数模型对实验数据进行很好的关联，其中平均相对偏差（ARD）小于2.50％，并且计算出的溶解度值显示与实验观察吻合良好。这项工作首先确定了AA和GA以及SA和GA的相互作用参数。然后通过改进的Apelblat方程和改进的非随机二液（NRTL）活度系数模型对实验数据进行很好的关联，其中平均相对偏差（ARD）小于2.50％，并且计算出的溶解度值显示与实验观察吻合良好。这项工作首先确定了AA和GA以及SA和GA的相互作用参数。
