摘要

在高压下，CO2在二元体系中各种溶剂中的溶解度是生产微粒子和纳米粒子的重要关键。本文比较了适用于微粒子和纳米颗粒生产的20种不同二元体系中CO2溶解度的Peng-Robinson (PR)、sove - redlich - kwong (SRK)和统计关联流体理论(SAFT)三种不同的状态方程。研究了二元体系的温度和压力对CO2在有机溶剂中的溶解度的影响。可以观察到，在相同温度下，CO2在溶剂中的溶解度随压力的增加而增加。在较高的压力下，液相主要是CO2，这些条件对超临界流体过程感兴趣。

CO2 solubility modeling in the binary systems at high pressures

The solubility of CO2 in various solvents in the binary systems at high pressures is an important key for production of micro and nanoparticles production. This paper compares three different equations of state of Peng-Robinson (PR), Soave-Redlich-Kwong (SRK) and Statistical Associating Fluid Theory (SAFT) for correlating of CO2 solubility in the 20 different binary systems at high pressures applicable to micro and nanoparticles production. The effects of the temperature and pressure of binary systems on the solubility of CO2 in organic solvents have also been investigated. It is observed that the solubility of CO2 in solvents increases with the increase in the pressure at the same temperature. At higher pressures the liquid phase is mostly CO2 and these conditions are interested in supercritical fluid processes.
