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
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 ...

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.
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.
A pastor was arrested over allegations of his lewd, forceful sexual behavior from several workers at his cleaning company — just a day after he preached at his Oklahoma church about forgiveness.
For example, addition of S 2− ion to [Fe(CN) 5 (NO)] 2− produces the violet colour [Fe(CN) 5 (NOS)] 4− ion, which is the basis for a sensitive test for S 2− ions. An analogous reaction also exists with OH − ions, giving [Fe(CN) 5 (NO 2)] 4−. [49] Roussin's red salt (K 2 [Fe 2 S 2 (NO) 4]) and Roussin's black salt (NaFe 4 S 3 (NO) 7 ...
