Abstract
Process for the manufacture of hydrazones, of the general formula ** (See formula) ** wherein R1 and R2 each represent hydrogen, lower alkyl, aryl or lower aryl, and R3 represents lower carboxyalkyl or carboxyl, and salts thereof, which process comprises condensing a dihydrazino triazine of the general formula ** (See formula) ** wherein R1 has the same meaning as indicated above, with an aldehyde carboxylic acid or ketocarboxylic acid of the general formula ** (See formula) ** where R2 and R3 have the same meaning as indicated above, and, if desired, to transform the product thus obtained into a salt.
