Abstract
Process for the preparation of substituted acidic hydrazides, and salts thereof, characterized in that it comprises condensing an acid of general formula R1-COOH into R1 represents an acyclic hydrocarbon radical bearing at least one substituent selected from the group consisting of halogen, hydroxy, alkoxy containing not more than 4 carbon atoms and alkylmercapto containing not more than 4 carbon atoms, with a substituted hydrazine of the general formula H2N-NH-R2 in which R2 represents a member selected from the group consisting of alicyclic hydrocarbon radicals having not more than 6 carbon atoms, saturated acyclic hydrocarbon radicals having not more than 6 carbon atoms and aralkyl radicals, in the presence of a carbodiimide, N, N'' - disubstituted and, if desired, converting the product of condensation in a salt.
