Abstract

油酸、水、壬酸和醋酸的混合体系在0~15℃、强烈搅拌下,再通臭氧至反应完全.再通氧气并使体系逐渐升温至85~100℃,向体系加入Mn(Ac)2和CoCl2做催化剂或用微波加热催化,反应2~3 h.使用近沸水萃取反应混合物,水相经冷冻、抽滤、重结晶等工艺后得到壬二酸,油相经减压蒸馏得到副产品壬酸.由于采用的溶剂体系优良和选用的催化剂得当,壬二酸的收率达到70%以上(以油酸计),纯度大于98.4%.

Other Abstract

The mixture of oleic acid,water, pelargonic acid and acetic acid was treated with ozone at 0~ 15 e beforethe reaction was fully carried out .The resulting mixture was heated to 85~ 100 e and passed with oxygen gas for more 2~ 3 hours,with using Mn(Ac) 2 and CoCl2 as catalysts.Then azelaic acid and pelargonic acid were separated from the endproducts. The yield of azelaic acid was more than 70% ,with purity over 98. 4% .Microwave was also discovered to be agood catalytic method for the process.
