摘　　要：分析和对比液液萃取分离的溶剂,研究各种萃取剂对硫辛酸、乙醇和水混合溶液萃取分离的影响;以UNIQUAC方程为模型,采用正庚烷为萃取剂模拟计算液液萃取分离结果,表明在理论板数N=3时,硫辛酸的收率达89.5%,纯度可达99.5%以上,正庚烷是分离的较好萃取剂,为硫辛酸萃取分离试验提供了理论依据。Effect of Solvents on liquid-liquid extraction. Separation of lipoic acid and ethanol equeous was studied. Results of liquid-liquid extraction. Separation were calcuhed with n-pentane by UNIQUAC equation. The results show that recovery ratio of lipoic acid reach 89.5%. The pure component of lipoic acid reachs 99. 5%. The simulation results was provided for lipoic acid test.
