METHOD OF PRODUCING CARBOXYLIC ACID AMIDES Russian patent published in 2015 - IPC C07C231/02 C07C233/06 C07D211/06 C07D211/16 C07D265/30 C07D295/23

Abstract RU 2565059 C1

FIELD: chemistry.

SUBSTANCE: method of producing carboxylic acid amides includes reacting a carboxylic acid with an amine in the presence of a catalyst in a solvent medium with azeotropic distillation of water. As the carboxylic acid butyric acid, valeric acid or isovaleric acid are used , and as the amine cyclohexylamine, piperidine or morpholine are used. As the catalyst copper nanoparticles are used, and the process occurs in a benzene medium with molar ratio of the carboxylic acid:amine:catalyst equal to 1:1.1-1.2:0.02-0.05. , where R₁=i-Bu, R₂R₃=(CH₂)₅; R₁=Bu, R₂R₃=(CH₂)₂O(CH₂)₂; R₁=Pr, R₂=H, R₃=cyclo-C₆H₁₁; R₁=Pr, R₂R₃=(CH₂)₅.

EFFECT: obtaining carboxylic acid amides in mild conditions with high output.
