Abstract

What is disclosed is the method for making an N-substituted acrylamide or an N-substituted methacrylamide which comprises reacting an alkyl ester of acrylic acid or of methacrylic acid with an aliphatic amine or with an aromatic amine at a temperature between 50.degree. C. and 180.degree. C. in the presence of a catalytic amount of a dialkyl tin oxide.
