Chemische Eigenschaften
Mercuric cyanide is an odorless, white crystalline solid; turns gray to dark brown when exposed to light
Verwenden
Mercuric cyanide finds veterinary application as a topical antiseptic for cats and other animals.
synthetische
One part of HgO is digested for a few hours on a water bath
with one part of Prussian blue and 10 parts of H2O. The mercuric cyanide crystals
separate on evaporation of the solution.
Allgemeine Beschreibung
Odorless tetragonal crystals or white powder. Toxic by inhalation (dust, and the hydrogen cyanide from decomposition) and by ingestion. Toxic oxides of nitrogen are produced in fires. It is used in medicine, germicidal soaps, photography, and in making cyanogen gas.
Air & Water Reaktionen
Soluble in water. Gradually decomposed by water to give off hydrogen cyanide, a flammable poison gas.
Reaktivit?t anzeigen
MERCURIC CYANIDE is rapidly decomposed by acids to give off hydrogen cyanide, a flammable poison gas. Decomposed in the light. May tend to explosive instability. Capable of violent reaction with oxidizing agents. Fusion with metal chlorates, perchlorates, nitrates or nitrites can cause a violent explosion [Bretherick 1979. p. 101].
Hazard
Toxic by ingestion, inhalation, and skin
absorption.
Health Hazard
Mercuric cyanide is a highly poisonous compound. Its components, mercury(II) and the cyanide ions, are both highly toxic. Its toxicity, however, is lower than that of sodium and potassium cyanides.
Acute toxic symptoms from oral intake of this compound in humans are hypermotility, diarrhea, nausea or vomiting, and injury to kidney and bladder. Toxic symptoms may be manifested in humans from consuming 15–20 g of this compound. Lower doses may produce somnolence. An intraperitoneal dosage of 7.5 mg/kg was fatal to rats.
LD50 value, oral (mice): 7.5 mg/kg.
Brandgefahr
Special Hazards of Combustion Products: Fumes from fire may contain toxic mercury and hydrogen cyanide.
Sicherheitsprofil
Poison by ingestion,
subcutaneous, intravenous, and
intraperitoneal routes. Human systemic
effects by ingestion: nausea or vomiting,
hypermotility, dlarrhea, kidney changes,
somnolence. Hydrolyzes to toxic fumes. A
frictionand impact-sensitive explosive. It
may initiate detonation of liquid hydrogen
cyanide. Incompatible with fluorine,
magnesium, sodium nitrite. When heated to
decomposition it emits very toxic fumes of
Hg, NOx, and CN-. See also CYANIDE
and MERCURY COMPOUNDS.
m?gliche Exposition
Mercuric cyanide is used in medicine,
germicidal soaps, photography and in making cyanogen
gas
Versand/Shipping
UN1636 Mercuric cyanide, Hazard Class: 6.1;
Labels: 6.1-Poisonous materials
l?uterung methode
Crystallise it from water. The solubility in H2O is 8% at ~20o and 33% at ~100o; in EtOH it is 8% at ~20o and in MeOH it is 25% at ~20o. [Blitz Z Anorg Allgem Chem 170 161 1928.] POISONOUS.
Inkompatibilit?ten
Violent reaction with fluorine, magnesium, sodium nitrite, acids. Heating or contact with acid
releases toxic mercury and flammable hydrogen cyanide
gas. Incompatible with 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
Waste disposal
Return to supplier for mercury recovery and deactivation.
