Sodium cyanide is a compound with the formula Na C N and the structure Na + − C≡N. It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals. It is a moderately strong base.
Among the most toxic cyanides are hydrogen cyanide (HCN), sodium cyanide (NaCN), potassium cyanide (KCN), and calcium cyanide (Ca(CN) 2). The cyanide anion is an inhibitor of the enzyme cytochrome c oxidase (also known as aa 3), the fourth complex of the electron transport chain found in the inner membrane of the mitochondria of eukaryotic ...

Kohinoor Chemical Company (Bangladesh) Limited was established in 1956 at Tejgaon Industrial Area, Dacca. [8] [9] In 1971, the company was nationalized after the Independence of Bangladesh from Pakistan and placed under Bangladesh Chemical Industries Corporation. [8] It became a public limited company in 1998. [8]
Reaction of the sodium cyanoacetate with ethyl bromide in an aqueous–organic two-phase system in the presence of a phase transfer catalyst. [ 4 ] Oxidation of 3-ethoxypropionitrile, an ether , with oxygen under pressure in the presence of cobalt(II) acetate tetrahydrate as catalyst and N -hydroxyphthalimide as a radical generator.
In the laboratory, this compound may be prepared by treating sodium cyanide with acetone, followed by acidification: [3]. Considering the high toxicity of acetone cyanohydrin, a lab scale production has been developed using a microreactor-scale flow chemistry [4] to avoid needing to manufacture and store large quantities of the reagent.
Sodium cyanate is isostructural with sodium fulminate, confirming the linear structure of the cyanate ion. [3] It is made industrially by heating a mixture of sodium carbonate and urea. [4] Na 2 CO 3 + 2 OC(NH 2) 2 → 2 NaNCO + CO 2 + 2 NH 3 + H 2 O. A similar reaction is used to make potassium cyanate. Cyanates are produced when cyanides are ...
