摘要
采用尿素包合法从亚麻油中提取α -亚麻酸。实验运用正交设计 ,考察了包合反应中温度、溶剂配比、时间等因素对产品中α -亚麻酸含量的影响 ,找出了优化条件。实验结果显示 ,α -亚麻酸产品纯度达 87%以上 ,α -亚麻酸的收率在 6 0
In the paper,the purification process of α-linolenic acid was studied with orthogonal experimental design method.The factors such as operation temperature,adduction time and the feed ratio of Urea and MeOH to fatty acids,which effect the α-linolenic acid purity and yield remarkably,were discussed in details based on the theory of Urea adduction fractionation.The research obtained an optimum results on operation condition of separation processes for pure α-linolenic acid.
