Abstract

The solubility of four recently synthesized 1,8-dihydroxy-9,10-anthraquinone derivatives, as potential complexing agents in some extraction and membrane transport experiments, have been measured in supercritical carbon dioxide. The measurements were carried out in the pressure range 120-400 atm at temperatures 35, 45, 55, 65, and 75 degrees C. The measured solubilities were correlated using the model proposed by Chrastil. The calculated results show good agreement with the experimental data.

摘要

四种最近合成的1,8 - 二羟基 - 9,10 - 蒽醌衍生物作为某些萃取和膜传输实验中潜在的络合剂，其在超临界二氧化碳中的溶解度已被测定。测量在120 - 400个大气压的压力范围内、35、45、55、65和75摄氏度的温度下进行。使用Chrastil提出的模型对测得的溶解度进行关联。计算结果与实验数据显示出良好的一致性。
