543-90-8

Cadmium acetate is colorless crystal with a characteristic odor. It is not combustible, but it decomposes on heating, producing toxic fumes of cadmium oxide. It is incompatible with oxidizing agents, metals, hydrogen azide, zinc, selenium, and tellurium. Occupational exposure to cadmium and cadmium compounds occurs in workplaces mainly in the form of airborne dust and fumes. Occupations and workplaces include cadmium production and refi ning, nickel-cadmium battery manufacture, cadmium pigment manufacture and formulation, cadmium alloy production, mechanical plating, zinc smelting, soldering, and polyvinylchloride compounding. Cadmium and compounds enter the body mainly by inhalation and by ingestion

Odorless colorless solid. Sinks and mixes with water.

Salts, basic, such as CADMIUM ACETATE(543-90-8), are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Special Hazards of Combustion Products: Toxic cadmium oxide fumes may form in fires [USCG, 1999].

Slowly oxidized by moist air to form cadmium oxide [Merck 11th ed. 1989]. Water soluble.

Exposures to cadmium acetate cause cough, skin redness, abdominal pain, nausea, vomiting, salivation, choking, dizziness, and diarrhea. On catching fi re, cadmium acetate gives off irritating or toxic metal oxide fumes. Inhalation of dust produces perforation of the nasal septum, loss of smell, irritation, headache, metallic taste, and cough. Prolonged exposures to cadmium acetate may produce shortness of breath, chest pain, and fl u-like symptoms, chills, weakness, fever, muscular pain, pulmonary edema, liver and kidney damage and death. Cadmium acetate may have effects on the kidneys and bones, leading to kidney impairment and osteoporosis (bone weakness), and liver damage. Accidental ingestion or inhalation of cadmium acetate may be fatal to workers

Inhalation causes coughing, sneezing, symptoms of lung damage. Ingestion produces severe toxic symptoms; both kidney and liver injuries may occur. Contact with dust causes eye irritation.

Cadmium acetate is a colorless crystalline solid; freezing/melting point 5 130C. Hazard identification (based on NFPA-704 M Rating System): Health 3, flammability 0, reactivity 0. Soluble in water

Special Hazards of Combustion Products: Toxic cadmium oxide fumes may form in fires.

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

UN2570 Cadmium compounds, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water, and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, sulfides (releasing heat, toxic, and possibly flammable gases), thiosulfates, and dithionites (releasing hydrogen sulfate and oxides of sulfur). 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

Precipitation as sulfide, drying and return to supplier. Incineration is not recommended.

The anhydrous salt occurs as a colorless crystal while the dihydrate is a white crystalline solid; faint odor of acetic acid; density 2.34 g/cm³ (dihydrate2.01 g/cm³); melts at 255°C; dihydrate decomposes at 130°C; soluble in water and ethanol; pH of 0.2M aqueous solution 7.10.

Cadmium acetate is used for glazing ceramics and pottery; in electroplating baths; in dyeing and printing textiles; and as an analytical reagent for sulfur, selenium, and tellurium.

Cadmium acetate is prepared by treating cadmium oxide with acetic acid:
CdO + 2CH₃COOH → (CH₃COO)₂Cd + H₂O
Also, the compound may be prepared by treating cadmium nitrate with acetic anhydride.

Color Code—Blue: Health Hazard: Store in asecure poison location. Prior to working with Cadmiumacetate you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area away from heat and incompatible materialslisted above. A regulated, marked area should be established where this chemical is handled, used, or stored incompliance with OSHA Standard 1910.1045.
