摘要

1 引言物质在超临界流体中具有良好的溶解性能和传质特性。纯物质在超临界流体中溶解度的研究已取得较大进展。但对混合物溶解度研究的报道甚少。用超临界CO_2提取天然物已有大量文献报道。提取产物的组成和含量随实验条件有很大变化

其变化规律仅能从定性上给予说明。松节油是由多种化合物组成的混合物

主要含α-蒎烯和-蒎烯等萜烯。由于它们的挥发度等性质相近

若用传统精馏方法需要几十个塔板才能达到分离要求。本文用NOVA-4L超临界萃取装置对其进行分离研究

并考察其变化规律。 2 溶解度的计算公式谭飞等用超临界萃取的物理化学模型导出了物质在超临界流体中的溶解度

并给出精确度较高的半经验计算公式 (1)

Abstract

The solubility of turpentine was studied in surpercritical carbon dioxide with NOVA-4L supercritical fluid extraction apparatus. Empirical correlation for calculating the solubility of turpentine of a mixture of compounds with similar properties was established with the average error of 3. 5 percent lny=-5.659-4.658/Tr+0.2721Trσr+1.304ln(Trσr)The separation characteristics of α- pinene and β- pinene in turpentine are discussed.
