Synthesis of long chain unsaturated fatty acids by chemical chain elongation

摘要

Problem to be solved: to convert different unsaturated fatty acids by chemical elongation of carbon chain of unsaturated fatty acid. The problem of the present invention is to shorten the reaction step of the conventional method and complete the carbon chain elongation reaction in a shorter time.Solution: a short pathway conversion reaction of an unsaturated fat chain derived from unsaturated fatty acids into malonic ester derivatives and four steps of heating and reflowing the malonate ester derivative in a lower fatty acid solution A method of prolonging carbon chains of unsaturated fatty acids by two carbon atoms is provided. The method of the present invention can complete the carbon chain elongation reaction in a shorter time.No selection
