Sodium cyanide is produced by treating hydrogen cyanide with sodium hydroxide: [4] HCN + NaOH → NaCN + H 2 O. Worldwide production was estimated at 500,000 tons in the year 2006. Formerly it was prepared by the Castner process involving the reaction of sodium amide with carbon at elevated temperatures. NaNH 2 + C → NaCN + H 2
Na 2 SnO 3: sodium stannate: 12058–66–1 Na 2 Te: sodium telluride: 12034–41–2 Na 2 Ti 3 O 7: sodium metatitanate: 12034–36–5 Na 2 WO 4: sodium tungstate: 13472–45–2 Na 3 AlF 6: sodium hexafluoroaluminate: 13775–53–6 Na 3 Co(NO 2) 6: sodium cobaltnitrite: 14649–73–1 Na 3 PO 4: sodium phosphate: 7601–54–9 Na 3 Sb ...
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 ...
Potassium dicyanoaurate (or potassium gold cyanide) is an inorganic compound with formula K[Au 2]. It is a colorless to white solid that is soluble in water and slightly soluble in alcohol . The salt itself is often not isolated, but solutions of the dicyanoaurate ion ( [Au(CN) 2 ] − ) are generated on a large scale in the extraction of gold ...
2OC(NH 2) 2 + Na 2 CO 3 → 2Na(NCO) + CO 2 + 2NH 3 + H 2 O. Sodium allophanate is observed as an intermediate: [2] H 2 NC(O)NHCO 2 Na → NaOCN + NH 3 + CO 2. It can also be prepared in the laboratory by oxidation of a cyanide in aqueous solution by a mild oxidizing agent such as lead oxide. [3]
Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: . 2 Hg(CN) 2 → (CN) 2 + Hg 2 (CN) 2 Or, one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides; an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.
Nitrilotriacetic acid (NTA) is the aminopolycarboxylic acid with the formula N(CH 2 CO 2 H) 3. It is a colourless solid. It is a colourless solid. Its conjugate base nitrilotriacetate is used as a chelating agent for Ca 2+ , Co 2+ , Cu 2+ , and Fe 3+ .
Sodium thiocyanate (sometimes called sodium sulphocyanide) is the chemical compound with the formula NaSCN. This colorless deliquescent salt is one of the main sources of the thiocyanate anion . As such, it is used as a precursor for the synthesis of pharmaceuticals and other specialty chemicals . [ 2 ]
