溶质在超临界流体中的溶解度与流体的密度密切相关。本文采用微扰硬球链理论对纯CO2 及 CO2 -正戊烷、CO2 -正庚烷、CO2 -正癸烷体系在不同条件下的密度进行计算 ,计算值与文献给出的实验值符合很好
The solubility of solute in a supercritical fluid is closely related to the density of the fluid. In this paper, we calculated the density of pure CO2 and CO2-n-pentane, CO2-n-heptane and CO2-n-decane systems under different conditions by using the theory of perturbation hard-chain. The calculated values are in good agreement with the experimental data
