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
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: sodium antimonide: 12058–86–5 ...
The cyanide compound sodium nitroprusside is used mainly in clinical chemistry to measure urine ketone bodies mainly as a follow-up to diabetic patients. On occasion, it is used in emergency medical situations to produce a rapid decrease in blood pressure in humans; it is also used as a vasodilator in vascular research.
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 ...
Cyanuric chloride is employed as a reagent in organic synthesis for the conversion of alcohols into alkyl chlorides, [8] and carboxylic acids into acyl chlorides: [9]. It is also used as a dehydrating agent, e.g. in the conversion of amides to nitriles, [10] and for the activation of carboxylic acids for reduction to alcohols.
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 .
Potassium hexacyanidoferrate(II) is produced industrially from hydrogen cyanide, iron(II) chloride, and calcium hydroxide, the combination of which affords Ca 2 [Fe(CN) 6]·11H 2 O. This solution is then treated with potassium salts to precipitate the mixed calcium-potassium salt CaK 2 [Fe(CN) 6 ], which in turn is treated with potassium ...
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.
