| 摘 要： | 测定了苯酚在压力8.5~16.0MPa、温度373.15~398.15K范围内超临界CO2中的溶解度。结果表明，苯酚溶解度随压力的增加而增大；温度对溶解度的影响要相对复杂，当压力低于转变压力11.0MPa时，溶解度随温度的增加而减小，当压力高于11.0MPa时，溶解度随温度的增加而增加。分别用Peng-Robinson状态方程和Chrastil密度型模型关联了溶解度数据，平均绝对偏差分别为9.25%和6.33%，两者吻合良好。 |

| Abstract: | The solubility of phenol in supercritical carbon dioxide was measured under the pressure ranging from 8.5 to 16.0 MPa and the temperature from 373.15 to 398.15 K.The experimental results showed that the solubility of phenol in supercritical CO2 increased with pressure,while the effect of temperature on the solubility of phenol was complicated.To be exact,the solubility increased with temperature when the pressure exceeded the retrograde pressure of 11.0 MPa,while the increasing temperature led to decrease of the phenol solubility when the pressure was below1 1.0 MPa.The experimental solubility data were correlated by using the Peng-Robinson equation of state with the van der Waals mixing rule,and the density-based model proposed by Chrastil,inwhich the values of the average absolute relative deviation were 9.25%and 6.33 %,respectively,indicating the correlation results were fairly good. |
