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
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.
Uses
Sympathetic inks, paint and varnish driers, catalyst, anodizing, mineral supplement in feed additives, foam stabilizer.
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.
