APPLICATIONS |
||
| Guanidine, also called carbamidine, is a strongly alkaline and water-soluble compound, NHC(NH2)2 It is formed in urine as a normal product of protein metabolism in the body by the oxidation of guanine. Guanidine has imine group and aminoacetal functional group in the small structure. Aminoacetal (aminal) is the functional group which has two amine groups attached to the same carbon atom. Imine is a compound containing the bivalent =NH group combined with a bivalent nonacid group, as R-HC=NH. It is produced by the condensation reactions of aldehydes or ketones with ammonia (or amines). Imino is a prefix denoting the presence of the bivalent group =NH attached to nonacid radicals. Imine can reduced and hydrolysed to prepare corresponding amines. Imine is involved in Diels-Alder reaction, Povarov reaction, Aza-Baylis-Hillman reaction and Eschweiler-Clarke reaction. In industry, guanidine, containing nitrogens and N=C solid 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. | ||
