Potassium cyanide - Wikipedia
Potassium cyanide is a potent inhibitor of cellular respiration, acting on mitochondrial cytochrome c oxidase, hence blocking oxidative phosphorylation. Lactic acidosis then occurs as a consequence of anaerobic metabolism.
E. Substitution Reactions Involving Cyanide Ions
Jan 23, 2023 · This page gives you the facts and simple, uncluttered mechanisms for the nucleophilic substitution reactions between halogenoalkanes and cyanide ions (from, for example, potassium cyanide).
Potassium Cyanide - KCN - BYJU'S
Potassium cyanide (KCN) was an important source of alkali metal cyanides before the invention of the Castner process. It was produced by the decomposition of potassium ferrocyanide. The reaction is as follows: K4[Fe (CN)6] → 4 KCN + FeC2 + N2. It is a highly poisonous compound which acts as an inhibitor for many metabolic processes.
Potassium Cyanide - an overview | ScienceDirect Topics
Reaction with potassium cyanide (KCN) generates hexanenitrile, whereas reaction with silver cyanide (AgCN) yield the isomeric isonitrile, 1-isocyanopentane. If the reaction is done in alcoholic solvents, which minimizes the nucleophilicity of ionic species due to solvation effects, the yield of isonitrile is improved.
ANALYTICAL METHODS - Toxicological Profile for Cyanide - NCBI Bookshelf
Free cyanides such as sodium cyanide, potassium cyanide, and hydrogen cyanide are readily ionized to the cyanide ion under the conditions used in most common analytical techniques. Methods for determining cyanide amenable to chlorination measure simple metal cyanides and most complex cyanides with the exception of iron cyanides.
Potassium Cyanide - an overview | ScienceDirect Topics
The common cyanides are potassium cyanide (KCN) and sodium cyanide (NaCN), both of which are highly toxic cyanides that enter the human body through wound contact, inhalation, and swallowing, and are rapidly ionized to CN –.
HEALTH EFFECTS - Toxicological Profile for Cyanide - NCBI Bookshelf
Cyanide (as hydrogen cyanide), originating in vivo by dissociation of potassium cyanide, sodium cyanide, and other cyanogenic compounds or arising from catabolism of cyanogenic glycosides, exerts its acute toxic effects by complexing with the ferric iron atom in metalloenzymes, resulting in histotoxic anoxia through inhibition of cytochrome c ...
Non-toxic cyanide sources and cyanating agents
Aug 30, 2018 · Over the years, many approaches towards non-toxic alternatives for cyanation reactions have been reported. All these approaches fall into two classes. One class of cyanide sources contains a tightly bound cyano group that needs to be liberated for the reaction to occur.
Potassium Cyanide - an overview | ScienceDirect Topics
Cyanide salts (sodium cyanide [NaCN], potassium cyanide [KCN]), when ingested, are converted to HCN in the presence of gastric acid, which is then absorbed. Cyanide binds to heme iron in the cytochrome complex, and the result is the inhibition of oxidative phosphorylation.
Potassium Cyanide | KCN | CID 9032 - PubChem
Mar 22, 2009 · Potassium cyanide is a cyanide salt containing equal numbers of potassium cations and cyanide anions. It has a role as an EC 1.9.3.1 (cytochrome c oxidase) inhibitor, an EC 1.15.1.1 (superoxide dismutase) inhibitor and a neurotoxin.
