The heats of ignition and volumes of the gases released on combustion of various solid hydrazones with nitric acid as oxidizer, have been determined. The experimental values when compared with those calculated indicate incomplete combustion. Both, the heats of ignition and the volumes of gases generated appear to depend upon the substituent in the benzene ring of the hydrazone carbon atom. The électron releasing groups are found to enhance these combustion parameters in the case of phenylhydrazones whereas no such trend was noticed in the case of dimethylhydrazones. The combustion products of these systems have been analyzed by a mass spectrometer. The major products are found to be N 2 , CO, NO, H 2 O, CO 2 and N 2 O along with trace amounts of O 2 .
