刘雄民, 李飘英, 邹德正, et al. SOLUBILITY OF TURPENTINE AND SEPARATION OF α-PINENE AND β-PINENE IN SUPERCRITICAL CARBON DIOXIDE[J]. CIESC Journal, 1994, (1).DOI:
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.
