Nickel cyanide (CAS NO.557-19-7) is also called Nickel cyanide tetrahydrate ; Dicyanonickel ; Nickel(ii)cyanide ; Nickelcyanide(ni(cn)2) ; Rcrawastenumberp074 ; Dicyanonickel(II) . It reacts violently with magnesium. Nickel cyanide (CAS NO.557-19-7) is thermally unstable and easily oxidized. It produces toxic oxides of nitrogen in fires. Nickel cyanide is weakly basic. Liberates flammable and lethally poisonous hydrogen cyanide gas on contact with acids or acid fumes. Undergoes violent reactions with fluorine, hypochlorites, nitric acid, nitrates, nitrites. Undergoes an explosive reaction if melted with nitrites or chlorates (at about 450 °C). Emits highly toxic cyanide fumes when heated to decomposition. Undergoes an incandescent reaction if heated with magnesium. It is toxic by inhalation and ingestion. Irritating to skin and eyes. Nickel cyanide (CAS NO.557-19-7) is not flammable. |
