高纯度共轭亚油酸的制备
Research on the Preparation Method of High Purity Conjugated Linoleic Acid
摘要
Abstract
High purity conjugated linoleic acid（CLA） was prepared by means of urea adduct purification and conjugation by safflower oil.This paper is focused on two different synthesis methods：（1） alkaline catalysis-urea adduction fractionation,（2） saponification-urea adduction fractionation-alkaline catalysis.The processing parameters and the ratio of CLA isomers for each method were investigated.The result showed that the second method which was enriching linoleic acid（LA） first and then performing alkaline catalyzed conjugation was better.Under the optimal conditions,CLA of 97.22% purity was achieved;the total recovery of the product was 32.08%,the content of c9,t11-CLA and t10,c12-CLA were 45.14% and 49.12% respectively.关键词
