Dinitrates of malonyl and nitraminodiacetyl hydrazides

摘要

The hydrazides of malonic acid and nitraminodiacetic acid are used as starting materials to synthesize the corresponding dinitrates. The hydrazides can be obtained in good yields by the reaction of the carboxylic acid ethyl esters with hydrazine in aqueous media. The conversion into the nitrates was accomplished by the reaction with diluted nitric acid in a solvent mixture of ethanol and water. The new nitrates were characterized by NMR spectroscopy and elemental analysis. Densities of the salts were estimated and the thermal properties and sensitivities towards impact and friction were measured. The energetic properties were predicted with EXPL05 utilizing heats of formation calculated with the Gaussian program package.
