| | Cobalt acetate Usage And Synthesis |
| Uses | Cobalt(II) acetate is used for bleaching and drying varnishes and laquers. Other applications are: as a foam stabilizer for beverages; in sympathetic inks; as a mineral supplement in animal feed; and as a catalyst for oxidation. It also is used in aluminum anodizing solutions.
| | Preparation | Cobalt(II) acetate is prepared by dissolving cobalt(II) carbonate or hydroxide in dilute acetic acid, followed by crystallization. Also, it may be prepared by oxidation of dicobalt octacarbonyl in the presence of acetic acid.
| | Chemical Properties | Violet Crystalline Powder or Pale pink to purple Powder. Catalyzer for oxidizing dimethylbenzene, desiccant for coating, mordant for printing, accelerant for solidifying glass.
Cobalt(II) acetate is one of the compounds recommended for colouring the oxide layer formed on aluminium and its alloys by anodizing. | | Physical properties | Red-to-violet monoclinic crystals (anhydrous acetate is light pink in color); density 1.705 g/cm3; becomes anhydrous when heated at 140°C; soluble in water, alcohols and acids. | | Uses | Sympathetic inks, paint and varnish driers, catalyst, anodizing, mineral supplement in feed additives, foam stabilizer. | | Uses | Cobalt(II) acetate is used as an industrial catalyst. It is used as a precursor to various oil drying agents. It finds application in ion exchange agents, lubricants, plating agents and surface treating agents, greases, ink, toner, and colorant products. | | Definition | ChEBI: A cobalt salt in which the cobalt metal is in the +2 oxidation state and the counter-anion is acetate. | | General Description | Red-violet crystalline solid. Vinegar-like odor. | | Air & Water Reactions | Water soluble. Deliquescent | | Reactivity Profile | Salts, basic, such as Cobalt 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. | | Hazard | May not be used in food products (FDA). | | Health Hazard | Inhalation causes shortness of breath and coughing; permanent disability may occur. Ingestion causes pain and vomiting. Contact with eyes causes irritation. Contact with skin may cause dermatitis. | | Fire Hazard | Special Hazards of Combustion Products: Toxic cobalt oxide fumes may form in fire. | | Safety Profile | Poison by intravenous
route. Moderately toxic by ingestion.
Questionable carcinogen. Mutation data
reported. See also COBALT
COMPOUNDS. When heated to
decomposition it emits acrid smoke and
irritating fumes. |
