| 摘 要： | 使用带激光检测系统的实验设备，动态法测定了没食子酸在一系列乙醇+水混合溶剂中，温度范围为283~323K间的溶解度。分别采用Apelblat方程和Jouyban-Acree模型对实验数据进行了关联，关联结果的平均相对误差分别为0.63%和10.84%，Apelblat方程相比Jouyban-Acree模型能够更好的关联实验数据。没食子酸在不同配比的乙醇+水混合溶剂中溶解度均随温度升高而增大，随乙醇质量分数升高而增大，在乙醇质量分数为0.900的混合溶剂中有最大的溶解度。

| Abstract: | The solubility of gallic acid in binary mixtures of ethanol+water was determined at (283 to 323) K and atmospheric pressure using a dynamic method. The modified Apelblat equation and Jouyban-Acree model were used to correlate the solubility data, with the overall relative average deviation (RAD) values of 0.63% and 10.84%, respectively. The modified Apelblat equation thus shows the best agreement with experimental data. The solubility of gallic acid in binary mixtures increases with increasing temperature and mass fraction of ethanol in the mixed solvent and the maximum solubility of gallic acid can be reached with the mass fraction of ethanol 0.900. |
