Hydrogen cyanide (HCN), sometimes called prussic acid, is an organic compound with the chemical formula HCN. It is a colorless, extremely poisonous and flammable liquid that boils slightly above room temperature, at 25.6 Â°C (78.1 Â°F).
exists and is an alternate of . React gaseous ammonia (NH3), natural gas (CH4) and air using a platinum catalyst. This will form hydrogen cyanide gas (HCN). Usually, you'll then want to turn the HCN into sodium cyanide liquid (NaCN), which means reacting sodium hydroxide (NaOH) and HCN together in an absorber. You then may want to turn this into an almost pure NaCN solid product, which means cooling the liquid until solid particles crystallise out.
