Dicyanodiamide: represents flavourless colourless crystals with specific bitterish smack, it is well dissolved in warm air and especially in hot water, restrictedly we will dissolve in cold water, relatively we will dissolve in alcohol and liquid ammonia, we will not dissolve in benzene and cold air. On chemical to properties it is similar to cyanamide.
Melting temperature - 209 °C, density - 1,405 g/cm ³.
Chemical formula: C2P4N4.
Contain in sewage of productions of plastic, glues, melamine, pharmaceutical productions.
Receive from calcium cyanamide under the influence of acetic acid or dimerization of cyanamide at its heating to melting temperature.
Dicyanodiamide is of very great interest as the hidden hardener allowing to create high - strength unicomponent epoxy glues with a long period of storage.
It is applied as a hardener of "hot" hardening of epoxies by production of plastics, ditsiandiamidoformaldegidny pitches, varnishes, fabrics, cyanic connections, hydrazine salts.
It is used in production of biofireproof fiber boards for impregnation of a tree in the fire - prevention purposes.
Is an initial product by production of melanin, a guanidin, sulfanylamide medicines, epoxies, synthetic dubitel (sintan), explosives (nitroguanidin), and also some medicines, for example, of luminal.
