Method for synthesizing fatty acid monoethanolamide by using supported catalyst

The invention discloses a method for synthesizing fatty acid monoethanolamide by using a supported catalyst, which comprises the following steps: preparing a zinc oxide supported catalyst under an alkaline condition by using zinc salt, copper salt, CMEA and alkali as raw materials; and (2) adding the zinc oxide supported catalyst obtained in the step (1) into grease and monoethanolamine serving as raw materials, introducing nitrogen, reacting to synthesize fatty acid monoethanolamide, and filtering out the zinc oxide supported catalyst to obtain the product. The surfactant CMEA is added into the zinc oxide supported catalyst prepared by the invention, so that the particle size of the catalyst is uniform, the distribution is more uniform, and the reaction activity of the catalyst is improved; according to the method for synthesizing fatty acid monoethanolamide by using the zinc oxide supported catalyst prepared by the invention, the reaction conversion rate is increased, the reaction conditions are mild, no so
