Abstract
Process for the manufacture of mono- and dihydrazinotriazines of the general formula *** 1 (See formula 1) in which R1 represents hydrazino, hydroxy, carboxy, alkyl or aralkyl and R2 represents hydrogen, hydroxy, carboxy, aryl, aralkyl and, in the case that R1 is a hydrazino group, additionally alkyl, and acid addition salts thereof, which method comprises treating a mono- or dimercaptotriazine of the general formula *** 2 (See formula 2) in the which R3 represents hydrogen or methyl, R4 represents -SR3, hydroxy, carboxy, alkyl or aralkyl and R2 represents hydrogen, hydroxy, carboxy, aryl, aralkyl and, in the case where R4 is an SR3 group, additionally alkyl, with hydrazine or hydrazine hydrate.
