cyanamide's Usage Examples:

This diazo compound is decomposed by caustic alkalis with the formation of cyanamide and hydrazoic acid, CH4N3 N03N3H+CN NH2+ HN03, whilst acetates and carbonates convert it into amidotetra zotic acid, H2N C?NH - N.

, and the sodium cyanamide in contact with the residual carbon forms sodium cyanide.

Nascent hydrogen reduces cyanamide to ammonia and methylamine.

Heated in a current of carbon dioxide sodamide yields caustic soda and cyanamide, and with nitrous oxide it gives sodium azoimide; it deflagrates with lead or silver nitrate and explodes with potassium chlorate.

It appears that with soils which are not rich in humus or not deficient in lime, calcium cyanamide is almost as good, nitrogen for nitrogen, as ammonium sulphate or sodium nitrate; but it is of doubtful value with peaty soils or soils containing little lime, nor is it usefully available as a top-dressing or for storing.

The manufacture of alcohol from the sulphite lyes of the wood-pulp industry was contemplated, but carbide, although produced in increasing quantities, was not considered as a possible raw material owing to its greater importance as a source of the fertilizer cyanamide.

The formation of nitrides and cyanamides by actions of this kind and their easy conversion into ammonia is a useful method for fixing the nitrogen of the atmosphere and rendering it available for manurial purposes.

33 28, 3329 (1901)] prepare sodium cyanamide by melting sodium with carbons or some hydrocarbon, and passing ammonia over the melt at from 400 0 -600° C.

to form (1) oxides and nitric acids, (2) ammonia, (3) readily decomposable nitrides, (4) cyanides, (5) cyanamides.

Calcium cyanamide has assumed importance in agriculture since the discovery of its economic production in the electric furnace, wherein calcium carbide takes up nitrogen from the atmosphere to form the cyanamide with the simultaneous liberation of carbon.

On warming with sodium, it yields cyanamide.
