Dicyandiamide Chemical Properties,Usage,Production

Chemical Properties

white powder

Uses

Dicyandiamide is a guanidine derivative used in the synthesis of barbiturates,it is also used in the plastics industry (manufacture of melamine).

Uses

In the plastics industry (manufacture of melamine). In the pharmaceutical industry (barbiturates, guanidine derivatives).

Uses

Dicyandiamide is used in the synthesis of barbiturates. It is used as a stabilizer of ammonium dinitramide melt. It is used as hardener.

Production Methods

Dicyanodiamide is manufactured by dimerization of cyanamide in aqueous solution. The 25% cyanamide solution produced is adjusted to pH 8–9 and held at approximately 80C for 2 h to give complete conversion. The hot liquor is filtered and transferred to a vacuum crystallizer, where it is cooled. The crystals or dicyanodiamide are separated in continuous centrifuges and passed to rotary driers. In 1990, the total worldwide production of dicyanodiamide was about 30,000 tons.

General Description

Dicyandiamide is commonly used for the curing of epoxy resins. It is a nitrification inhibitor that is said to be capable of reducing nitrate (NO3-) leaching and nitrous oxide (N2O) emissions from grazed pasture soils.

Purification Methods

Recrystallise cyanoguanidine from water or EtOH. [Beilstein 3 IV 160.]
