| 摘 要： | 采用尿素包合技术从蚕蛹毛油中提纯α-亚麻酸,纯度为71.3%,再应用刮膜式分子蒸馏设备对α-亚麻酸进一步纯化;最佳工艺参数为:蒸馏温度110℃、蒸馏压力3.0 Pa、进料速度1.5ml/min、刮膜器转速450 r/min,在此条件下,α-亚麻酸纯度可达88.7%;经四级分子蒸馏,可将α-亚麻酸纯度提高至91.2%。

| Abstract: | α-linolenic acid was separated from silkworm pupa oil by urea adduction fractionation with the purity of 71.3%.The technology of refining α-linolenic acid by wiped film molecular distillation has been studied.The favorable method of molecular distillation process is:distillation temperature 110℃,system pressure 3.0 Pa,feed rate1.5 ml/min,and agitating speed 450r/min.The purity of α-linolenic acid can reach 88.7%,as well as 91.2% by 4 stages molecular distillation。 |
