| 摘 要： | 采用动态法分别测定了丁香油中主要成分丁香酚、乙酰丁香酚和β-石竹烯在超临界CO2中的溶解度。实验结果表明：三种成分在超临界CO2中的溶解度随着压力的增加而增大，随温度的增加而变小。在压力10-30MPa和温度313.15-333.15K范围内，丁香酚在超临界CO2中的溶解度(摩尔分数)为0.0002 -0.0580，乙酰丁香酚在超临界CO2中的溶解度(摩尔分数)为0.00018-0.07030，β-石竹烯在超临界CO2中的溶解度(摩尔分数)为0.00034-0.07096。采用Chrastil方程及其改进方程（Adachi、del Valle）分别对三种化合物在超临界CO2中的溶解度数据进行了关联，对丁香酚关联的AARD值分别为4.92%、4.47%、5.19%，对乙酰丁香酚关联的AARD值分别为3.69%、2.91%、3.24%，对丁香酚关联的AARD值分别为4.77%、4.41%、4.21%。

| Abstract: | The solubilities of eugenol, eugenol acetate and β-caryophyllene, which are the main components in clove oil, in supercritical CO2 were separately determined at the temperature range from 40℃ to 60℃ and pressure from 10 MPa to 30 MPa.The results showed that the solubilities of these components increased with increasing pressure or decreasing temperature.The solubility of β-caryophyllene was higher than those of eugenol and eugenol acetate at the same temperature and pressure.The solubilities of eugenol in SC-CO2 were between 0.0002 and 0.0580 (mole fraction）.The solubilities of β-caryophyllene in SC-CO2 were between 0.00034 and 0.07096 (mole fraction）.The solubilities of eugenol acetate in SC-CO2 were between 0.00018 and 0.07030 (mole fraction）.The solubility data of the main components of clove oil in SC-CO2 were correlated with the Chrastil equation and improved Chrastil equations presented by Adachi and del Valle.The values of average-absolute-relative-deviation(AARD) for eugenol solubility correlation were 4.92%,4.47%,5.19% respectively.The values of AARD for eugenol acetate solubility correlation were 3.69%,2.91%,3.24% respectively. The values of AARD for β-caryophyllene solubility correlation were 4.77%,4.41%,4.21% respectively. |
