Abstract
Aminoalkylhydrazines wherein the amino group contains at least one free hydrogen atom are prepared by reacting ethylene imine or its derivatives substituted on the carbon atoms and/or on the nitrogen atom with hydrazine or with substituted hydrazines or with substances which readily give off hydrazine or substituted hydrazines under the conditions of the reaction. Examples are given of the preparation of b -aminoethyl-, N,N-bis-(b -aminoethyl)-, aminopropyl -, N, N - bis - (aminopropyl) -, aminoethyl-(diethyl-aminoethyl)- and N-phenylcarbamoyl-aminoethyl-hydrazine (the last identified as its hydrazone with salicylaldehyde). Specification 880,332 is referred to.
