Abstract
Diaminotriazines are manufactured by heating dicyandiamide with a guanidine salt of an organic carboxylic acid at temperatures adjacent to the melting point of dicyandiamide. The guanidine salt may be prepared by heating an ammonium salt of the organic carboxylic acid with dicyandiamide in the presence of an ammonium carbonate, and this preparation and the conversion to a diaminotriazine may constitute two phases of the same operation, consisting in heating an ammonium salt of the organic carboxylic acid with 5-15 per cent excess of dicyandiamide in the presence of an ammonium carbonate. The acid may be alkyl, aryl or aralkyl, substituted or not, and the third carbon atom of the triazine ring will correspondingly bear no substituent or an alkyl, aryl or aralkyl group. In examples: (1) 1 mol. of ammonium acetate and 1/2 mol. of dicyandiamide are heated with 1/4 mol. of ammonium carbonate, then a further 1 mol. of dicyandiamide is added and heating continued at 180-215 DEG C., producing methyl-diaminotriazine; (2) commercially pure butyric acid is heated with excess of ammonium sesquicarbonate and the product is heated with dicyandiamide to give propyl diaminotriazine.
