Hexamethylenetetramine is prepared by the interaction of methylene chloride with liquid ammonia under pressure at an elevated temperature. The ammonia is preferably employed in excess. When the reaction is complete, the excess of ammonia is distilled off and recovered, and the residual mass is treated with a solvent, such as chloroform or carbon tetrachloride, to dissolve the hexamethylenetetramine; the ammonium chloride which remains may be decomposed with hydrated lime and the recovered ammonia employed in the hexamethylenetetramine manufacture. Specification 195,602 is referred to.
