摘  要:
采用差重法测定了穿心莲内酯在超临界CO_2中的溶解度,并利用化学缔合模型对实验数据进行关联计算。实验结果表明:穿心莲内酯在超临界CO_2中的溶解度随着压力的增加而增大,随着温度的增加而减小,并符合经典的Chrastil表达式。

摘  要:
Solubility differences were used method to determine andrographolide in supercritical CO_2 with chemical association model to correlate the experimental data.The results showed that the solubility of andrographolide in supercritical CO_2 increases as pressure increases and decreases as the temperature rises.Such changes of solubilities obey the classical Chrastil model.
