BEHAVIOR OF THE HYDRONITROGENS AND THEIR DERIVATIVES IN LIQUID AMMONIA. I. AMMONOLYSIS OF HYDRAZINE SULFATE
Journal of the American Chemical Society
In 1899 Goldschmidt and Salcherl studied the distribution of hydrochloric, hydrobromic, nitric, and orthobenzoic acids between certain tertiary bases and aniline, which was used as the solvent. The process by which these bases were to a certain extent liberated from their salts by the action of the solvent was designated by the authors, in recognition of a certain analogy with hydrolysis, as aminolysis. I n 1905 Franklin2 brought to light the remarkable analogy that exists between the reactions
... tween the reactions involved in ordinary hydrolysis and the reactions in which ammonia effects the decomposition of various substances with formation of amides, imides, nitrides, or ammono-basic salts. In accordance with this analogy the breaking up of certain substances by the action of ammonia was appropriately regarded as a process of ammonolysis. Having felt the impetus given by the work of Franklin and his associates to research in the field of non-aqueous solvents, the authors have planned a series of investigations upon the behavior of the hydronitrogens and their derivatives in liquid ammonia. Hydrazine, or hydrogen dinitride, as it might be called, obviously bears a relation to ammonia empirically similar to that borne by hydrogen peroxide to water,Y while hydronitric acid, or hydrogen trinitride, may in a sense be regarded as analogous with the hypothetical higher oxides of hydrogen4 concerning which there has been some recent discussion. In case the hydrogen pernitrides in liquid ammonia possess properties similar to those of hydrogen peroxide in aqueous solution it is to be expected that under proper conditions they should act in a sense as oxidizing agents, or more strictly as nitridizing agents. One ultimate purpose of the research has therefore been to study the phenomena of ammono-oxidation, or nitridation. Another purpose has been to investigate the phase rule relations, especially the pressureconcentration curves, in the two component systems ( I ) ammonia, hydrazine, (2) ammonia, hydronitric acid, (3) hydrazine, hydronitric acid, and in the three-component system ammonia, hydrazine, hydronitric 2. fihystk.
