Bleidicyanid Chemische Eigenschaften,Einsatz,Produktion Methoden
Chemische Eigenschaften
white to yellowish powder(s); used in metallurgy [HAW93]
Allgemeine Beschreibung
A white to yellowish powder. Toxic by skin absorption, by ingestion, and by inhalation of dust, or hydrogen cyanide produced by slight decomposition. Produces toxic oxides of nitrogen in fires.
Air & Water Reaktionen
Slightly soluble in water and gradually decomposed by water evolving poisonous and flammable hydrogen cyanide.
Reaktivität anzeigen
LEAD CYANATE is decomposed by acids to give off hydrogen cyanide, a flammable poisonous gas. Tends to explosive instability. Capable of violent oxidation: fusion with metal chlorates, perchlorates, nitrates or nitrites can cause explosions [Bretherick, 1979 p. 101]. Reacts with incandescence with magnesium [Mellor, 1940, Vol. 4, 271].
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Brandgefahr
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
