Abstract

Methods for producing carboxylic amides involves combining near-stoichiometric amounts of carboxylic acid and amine in a reaction vessel and reacting under pressures greater than atmospheric pressure. Alternatively, an excess of amine is reacted with carboxylic acid at atmospheric pressure to produce a carboxylic amide.
