Hidrogén cianid

Hydrogen cyanide (HCN), sometimes called prussic acid, is a chemical compound with the chemical formula HCN. It is a colorless, extremely poisonous and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F). HCN is produced on an industrial scale and is a highly valuable precursor to many chemical compounds ranging from polymers to pharmaceuticals A hidrogén-cianid (HCN, régebbi nevén kéksav) keserűmandula szagú, könnyen párolgó, rendkívül mérgező, színtelen folyadék, forráspontja 26 °C. Molekulái lineáris felépítésűek, a szénatom a nitrogénatomhoz háromszoros kovalens kötéssel kapcsolódik. Legfőbb tautomerje a HNC (hidrogén-izocianid) Egy uniós rendeletben meghatározták a sárgabarackmagban előforduló hidrogén-cianid felső határértékét. Az Európai Unió Hivatalos Lapjában július 8-án jelent meg az EU 2017/1237 rendelete, amely módosítja az élelmiszerekben előforduló egyes szennyező anyagok felső határértékeiről szóló 1881/2006/EK rendeletet.Az új rendelet 8. szakasza alapján a végső. Hidrogén-cianid keletkezik kálium- vagy nátrium-cianid savval való elbontásakor. Iparilag metánból és ammóniából állítják elő magas hőmérsékleten (1000 K fölött), katalitikus oxidációval. Képződik ammónium-formiátból foszfor-pentoxiddal való vízelvonással is. (A hidrogén-cianid hidrolízise megfordítható folyamat.

Böngésszen milliónyi szót és kifejezést a világ minden nyelvén Cyanide and hydrogen cyanide (HCN) are classified as blood agents. They cause toxicity by forming a stable complex with ferric iron (Fe 3+ ) in cytochrome oxidase enzymes. This inhibits cellular respiration, oxygen utilization, and ATP production, causing deprivation of oxygen to the body at the cellular level ( Way et al. , 1988 )
