GENERAL DESCRIPTION & APPLICATIONS
Cyanamide, the amide of normal cyanic acid, is a white crystals melting at 45 C; readily soluble in water, alcohol and ether. It is prepared commercially by carbide process from carbonate derived from limestone or by the desulphurization of thiourea in the presence of catalyst (mercuric oxide). It is prepared also by the action of ammonia with cyanogen halides. It polymerizes to dicyandiamide when heated over 150 C and to tricyantriamide as well as to melamine. Its metal salt especially calcium cyanamide is an environmentally friendly multi-purpose fertilizer which reacts with water to release ammonia and calcium carbonate to supply nitrogen and lime to plants and soil. The commercial calcium cyanamide contains about 65% calcium cyanamide, which has nitrogen 20 - 24% w/w. It acts also as a defoliant, herbicide, soil insecticide, and weed killer. Its consumption as a fertilizer has been reduced. It is added to pig iron to impart nitrogen and to desulfurize steel. The reactivity of the nitrile functional group in calcium cyanamide makes it as a chief industrial raw material. It is used in the preparation of other products include dicyandiamide, urea, thiourea, and guanidine. It is used in the production of calcium cyanide. Cyanide plays an important role in extracting precious metals.
Dicyandiamide is the dimer. It is an intermediate for melamine which us the basic ingredient of amino plastics and resins. It is used in the production of wide range of organic chemicals including slow and continuous nitrogen release fertilizers; fire proofing agent; epoxy laminates for circuit boards, powder coatings and adhesives; water treatment chemicals; dye fixing, leather and rubber chemicals; explosives; pharmaceuticals. Dicyandiamide is also called cyanoguanidine.
Guanidine, also called carbamidine, is a strongly alkaline and water-soluble compound, NHC(NH2)2 It is formed by the oxidation of guanine in urine as a normal product of protein metabolism in the body. In industry, guanidine, containing nitrogens and N=C double bond, and its modified derivatives are versatile intermediates used in the manufacture of plastics, resins, rubber chemicals, nitroguanidines (explosives), photo chemicals, fungicides, and disinfectant. It has also biotechnological application of protein separation, purification and as a protein denaturant. It can be used as an oxygen scavenger to prevent corrosion damage. It is used as a component of rocket propellants because it produce a large amount of heat when burned.Members of cyanamide derivative
