Hydrazine Sentence Examples

Nitrogen combines with hydrogen to form ammonia, NH 3, hydrazine, N 2 H 4, and azoimide, N 3 H (qq.v.); the other known hydrides, N 4 H 4 and N5H5, are salts of azoimide, viz.

On reduction it gives a strongly reducing substance, probably hydrazine.

The aldehyde group also reacts with phenyl hydrazine to form two phenylhydrazones; under certain conditions a hydroxyl group adjacent to the aldehyde group is oxidized and glucosazone is produced; this glucosazone is decomposed by hydrochloric acid into phenyl hydrazine and the keto-aldehyde glucosone.

Its ethyl ester reacts with hydrazine to form hippuryl hydrazine, C,H 5 CO NH CH 2 CO NH NH 2, which was used by Curtius for the preparation of azoimide.

The diketotetrahydrotriazoles, or urazoles, are formed by condensing urea derivatives with hydrazine salts, urazole itself resulting by the action of urea or biuret on hydrazine or its salts.

This amidoguanidine decomposes on hydrolysis with the formation of semicarbazide, NH 2 CO NH NH 21 which, in its turn, breaks down into carbon dioxide, ammonia and hydrazine.

Amidoguanidine is a body of hydrazine type, for it reduces gold and silver salts and yields a benzylidine derivative.

It forms a hydrazone with phenyl hydrazine, and an oxime with hydroxylamine.

A colloidal selenium was obtained by C. Paal and C. Koch (Ber., 1905, 38, p. 526) by reducing selenious acid dissolved in an aqueous solution of sodium protalbate with hydrazine hydrate and hydrochloric acid, the precipitate obtained being then dissolved in sodium carbonate.

An improved method of preparation was found in the use of hippuric acid, which reacts with hydrazine hydrate to form hippuryl hydrazine, C 6 H 5 [[Conh Ch 2 Conh Nh]] 2, and this substance is converted by nitrous acid into diazo-hippuramide, C 6 H 5 [[Conh Ch 2 Co Nh N 2.0h]], which is hydrolysed by the action of caustic alkalis with the production of salts of hydrazoic acid.

Hydrazine azoimide, N 5 H 5, is also known.

Similarly, its violently exothermic reaction with hydrazine made this an extremely powerful propellant combination for rocket fuel in the late 1950s.

This fatal complication must be considered in anyone taking or contemplating the use of hydrazine sulfate.
