| 摘 要： | 利用动态法测定了超临界络合萃取中的一种重要络合剂——固体二乙基二硫代氨基甲酸二乙胺(Et2NH2DDC)在超临界CO2中的溶解度。实验的温度、压力范围分别是308.2~328.2K,10.0~30.0MPa;溶解度随着温度、压力的增大而增大。将实验结果用Chrastil缔合模型法进行关联,取得了比较好的关联精度。

| Abstract: | In this work, the solubilities of one chelating agent, Et2NH2DDC, in supercritical carbon dioxide were determined by a dynamic method in the pressure range 10.0~30.0MPa and at 308.2~328.2K. It was found that the solubilities increase with pressure and temperature. The experimental results were correlated by Chrastil association model and a good agreement was obtained. |
