新型烷醇酰胺的合成

Synthesis of New Alkanolamide

烷醇酰胺是一种重要的表面活性剂，一般由椰子油制备，国内由于缺乏椰子油资源，需大量进口。偿试用国内来源丰富的植物油为原料，如棉籽油和米糠油合成了新型的烷醇酰胺。研究表明，用棉油或米糠油和甲醇反应制得脂肪酸甲酯，然后在氮气保护真空条件下，使脂肪酸甲酯和二乙醇胺脱醇缩合，可高产地制得高活性１∶１５型的新型烷醇酰胺。

Alkanolamide is a kind of very important detergent.Generally it is made from coconut oil,which is lacking in our country and must be imported from other countries.This paper tries to make new alkanolamide form our country’plentiful plant oil like cotton seed oil or rice bran oil.The result shows:In presence of N 2 and in vacuum the new alkanolamides 1∶1 5 type are prepared in high yield by diethanolamine with fatty acid methyester,which is made by reacting methanol with rice bran oil or cotton seed oil.
