cyanamide , auch: cyanamid , auch: carbamonitrile

The main use of calcium cyanamide is in agriculture as a fertilizer.

Consequently, most commercial cyanamide is sold as an aqueous solution.

It is a dimer of cyanamide, from which it can be prepared.

It is produced in soil by decomposition of cyanamide.

The cyanamide factory at Odda ceased operation in 2002.

Today, cyanamide is used primarily as a herbicide.

He also produced ammonium sulphate out of the calcium cyanamide, because it was safer and better known.

Poles concentrated their efforts at manufacturing calcium cyanamide, which in the 1920s and 1930s was commonly used as a fertilizer.

American Cyanamid shipped its first carload of cyanamide fertilizer.

The main reaction exhibited by cyanamide involves additions of compounds containing an acidic proton.

Cyanamid developed many chemicals based on cyanamide chemistry, or more broadly nitrogen-based chemicals.

In early production, first calcium cyanamide is converted into dicyandiamide, then heated above its melting temperature to produce melamine.

Containing both a nucleophilic and electrophilic site within the same molecule, cyanamide undergoes various reactions with itself.

Calcium carbide reacts with nitrogen at high temperature to form calcium cyanamide:

Calcium cyanamide is prepared from calcium carbide.

The synthesis produces a solid mixture of calcium cyanamide (CaCN) and carbon.

Graphitic carbon nitride can be made by polymerization of cyanamide, dicyandiamide or melamine.

Cyanamide dimerizes to give 2-cyanoguanidine (dicyandiamide).

Thiourea can be produced by the reaction of hydrogen sulfide with calcium cyanamide in the presence of carbon dioxide.

Calcium cyanamide is also used as a wire-fed alloy in steelmaking, in order to introduce nitrogen into the steel.

Hydrogen cyanamide interacts with the cytokinin metabolic cycle, which results in triggering a new growth cycle.

Hence, this enzyme has one substrate, urea, and two products, cyanamide and HO.

Specifically, hydrogen cyanamide stimulates cell division and growth in dormant plants, causing budbreak when the plant is on the edge of breaking dormancy.

Derivatives of this compound are also referred to as cyanamides, the most common being calcium cyanamide (CaCN).

Microorganisms, e.g. the bacterium Myrothecium verrucaria, accelerate this process utilizing the enzyme cyanamide hydratase.
