ABSTRACT OF THE DISCLOSURE Aliphatic tertiary amines are prepared from primary or secondary amines by reaction with formaldehyde, and the N-methyl- olamines so formed are hydrogenated at temperatures of 50° to 200°C and pressures of 0.1 to 10 MPa in the presence of finely distributed palladium or catalysts containing palladium. The aliphatic tertiary amines produced according to the present invention are valuable intermediate products in the synthesis of pharmaceuticals, catalysts for the production of polyurethanes, bactericides, dye intensification agents, and deceleration agents.
