超临界CO2-共轭亚油酸乙酯萃取体系研究

摘要

A set of phase equilibrium equipment with window was adopted to measure the solubility ot IGLA - ethyl ester in SC - C02. Supercritical phase behavior can be further researched through observing the phase behavior changes in the equilibrium kettle. The solubility of CLA - ethyl ester in SC - CO2 were studied with Chrastil equation. The average error for the system of CLA - ethyl ester was 2.43 %.%利用带有视窗的相平衡装置对共轭亚油酸乙酯在超临界CO2中的溶解度进行了测定。并通过对相平衡釜内体系相态变化的观测，进一步研究超临界相行为。采用Chrastil经验方程对共轭亚油酸乙酯在超临界CO2中的溶解度进行模拟。共轭亚油酸乙酯体系计算值与实验值平均误差为2．43％。
