摘要
采用固定体积可视观察法测定了 CO2 +甲苯、CO2 +环己烷、CO2 +正丁醛、CO2 +异丁醛、CO2 +甲醇及 CO2 +乙醇二元体系的临界点性质 ,为超临界萃取和化学反应提供基础数据 .在对二元体系相行为与单组分超临界相行为进行比较的基础上 。
The Performance of supercritical fluid (SCF) as a solvent can be greatly affected by addition of an entrainer to the system. In this study, the constant volume visual method is used to measure the critical point properties of CO 2+toluene, CO 2+cyclohexane, CO 2+ n butyraldehyde, CO 2+ i butyraldehyde, CO 2+methanol and CO 2+ethanol binary systems. These properties provide a good basis for supercritical extraction and chemical reaction. The relationship between the critical point of CO 2+entrainer binary system and the critical point of supercritical carbon dioxide has been discussed. The phase behavior of single component system has been compared to that of CO 2+entrainer binary systems.
