Chemical Properties
Cupric cyanide is a yellowish-green powder which decomposes on heating.
Hazard
Toxic.
Safety Profile
Poison by
intraperitoneal route. See also CYANIDE
and COPPER COMPOUNDS.
Incompatible with magnesium. When heated
to decomposition it emits toxic fumes of
NOx and CN-.
Potential Exposure
Copper cyanide is used in electroplating copper on iron; and as an insecticide and a catalyst.
Incompatibilities
Contact with heat, strong acids (HCl, H2SO4, HNO3) forms deadly hydrogen cyanide gas. May release hydrogen cyanide on contact with moisture. Incompatible with strong oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, acetylene gas, and chemically active metals, such as potassium, sodium, magnesium, and zinc.
Waste Disposal
Copper-containing soluble wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. If recovery is not feasible, the copper can be precipitated through the use of caustics and the sludge deposited in a chemical waste landfill. Copper-containing wastes can be concentrated to the point where copper can be electrolytically removed and reclaimed. If recovery is not feasible, the copper can be precipitated by alkali; the cyanide destroyed by alkaline oxidation yielding a sludge which can be sent to a chemical waste landfill. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
Check Digit Verification of cas no
The CAS Registry Mumber 14763-77-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,6 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14763-77:
(7*1)+(6*4)+(5*7)+(4*6)+(3*3)+(2*7)+(1*7)=120
120 % 10 = 0
So 14763-77-0 is a valid CAS Registry Number.
