| 摘 要： | 用MPR-2模型计算溶质在含有和不含有夹带剂超临界CO2中的溶解度,把超临界CO2和夹带剂视为一个拟组分,并根据VDW-1混合规则求出拟组分的方程参数,将超临界三元体系的相平衡问题简化为超临界二元体系的相平衡问题。关联和计算了8种溶质(共268个数据点)在超临界CO2中的溶解度,模型计算值与文献的实验值相吻合。

| Abstract: | The solute solubilities in supercritical CO2 with and without cosolvent are calculated with the MPR-2 model.By taking supercritical CO2 and cosolvent as a pseudocomponent and calculating equation parameter of the pseudocomponent by VDW-1 mixing rule,ternary supercritical system is simpled to binary supercritical system.The solubility data of 8 solutes in supercritical CO2,which are given including 268 data,are correlated and calculated.The calculated results agree fairly with the experimental results. |
