Cocoanut oil monoethanolamine glycoside and preparation method thereof

A preparation method of cocoanut oil monoethanolamine glycoside comprises the following steps: providing coconut fatty acid monoethanolamine; putting the coconut fatty acid monoethanolamine and glucose into a reactor and performing glycosylation under the condition that a Lewis acid catalyst exists; after finishing the reaction, adding an alkali neutralizing agent and regulating the pH to be neutral so as to obtain a raw product of the cocoanut oil monoethanolamine glycoside. The obtained cocoanut oil monoethanolamine glycoside conforms to the structural general formula, wherein R is straight-chain alkyl of C8 to C16, and m is 1 to 3. The method provided by the invention belongs to direct glycosidation methods, the technological process is brief, the side effects are few, and the product quality is high. A cocoanut oil monoethanolamine glycoside nonionic surfactant overcomes the defect that coconut fatty acid monoethanolamine is not easy to dissolve in water.
