Claims4
A process for the preparation of a N,N-dialkyl-meta (or para)-toluamide, which comprises reacting meta(or para)-tolunitrile with a dialkylamine, with the alkyl group containing 1 to 4 carbon atoms, and water in the liquid phase in the presence of adipic acid as a catalyst at a temperature of 100.degree.-400.degree.C., the amounts of the dialkylamine and water being 0.8-3.0 mols and 0.8-5.0 mols respectively per mol of the tolunitrile and the amount of adipic acid being 0.001-15 mol percent based on the tolunitrile.
