카드뮴 아세트산 화학적 특성, 용도, 생산

개요
Cadmium acetate is a colourless crystal with a characteristic odour. It is not combustible, but it decomposes on heating, producing toxic fumes of cadmium oxide. It is incompatible with oxidising 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 fume. Occupations and workplaces include cadmium production and refining, 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.

물리적 성질
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.
용도
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.
제조 방법
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.
일반 설명
Odorless colorless solid. Sinks and mixes with water.
공기와 물의 반응
Slowly oxidized by moist air to form cadmium oxide [Merck 11th ed. 1989]. Water soluble.
반응 프로필
Salts, basic, such as Cadmium acetate, 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].
건강위험
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
화재위험
Special Hazards of Combustion Products: Toxic cadmium oxide fumes may form in fires.
Safety Profile
Confirmed human carcinogen. Poison by intraperitoneal route. An experimental teratogen. Other experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits toxic fumes of Cd. See also CADMIUM COMPOUNDS.
잠재적 노출
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
운송 방법
UN2570 Cadmium compounds, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
비 호환성
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
폐기물 처리
Precipitation as sulfide, drying and return to supplier. Incineration is not recommended.
주의 사항
During use and handling of cadmium acetate, occupational workers should be careful. Workers should use protective gloves and immediately remove contaminated clothing and shoes. The workplace should provide an eye-wash fountain and quick-drench facilities. During use of cadmium acetate, workers should avoid heat, flame, ignition sources, dust, and incompatibles.
