癸二酸溶解度的测定

Determination of Sebacic Acid Solubility

采用激光透射原理与化工中动态溶解度测定相结合的方法,通过对癸二酸在不同溶剂中溶解度的测定,为癸二酸生产工艺的改进提供基础数据。对得到的溶解度数据用λh方程进行回归拟合,结果表明λh方程的平均相对误差不超过2.2%。说明λh方程能够很好地关联本文所测定的实验数据。

For the purpose of providing the basic solubility datum for improving the process of producing sebacic acid, the solubility of sebacic acid in different solvents were determined by the method of adopting the laser transmission principle and the chemical dynamic solubility test unifies. The obtained solubility data were returned fitting by λh equation, the result showed that the average relative error of λh equation were no more than 2. 2%. It showed that λh equation was fit for connecting the empirical datum determined by this paper.
