The paper presents the results of microwave synthesis of a Zn-B-P-oxide catalyst, which actively absorbs the energy of microwave radiation, applied to the surface of an aluminum-reinforced Al/γ-Al₂O₃ carrier, in order to further intensify the process of acylation of diethylamine with m-toluic acid to diethylamide m-toluic acid (DETA) under conditions of exposure to a microwave field. The results obtained demonstrate the possibility of realizing the process of acylation of diethylamine with m-toluic acid in a thermal regime, which is formed in the reaction zone due to the transformation of microwave energy by the catalyst mass. The developed method of microwave acylation of diethylamine with m-toluic acid is superior to the existing analogs in technological and energy parameters.
