Кобальта ацетат химические свойства, назначение, производство
Химические свойства
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.
Физические свойства
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.
Использование
Sympathetic inks, paint and varnish driers, catalyst, anodizing, mineral supplement in feed additives, foam stabilizer.
Определение
ChEBI: A cobalt salt in which the cobalt metal is in the +2 oxidation state and the counter-anion is acetate.
Общее описание
Red-violet crystalline solid. Vinegar-like odor.
Реакции воздуха и воды
Water soluble. Deliquescent
Профиль реактивности
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.
Опасность
May not be used in food products (FDA).
Угроза здоровью
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.
Пожароопасность
Special Hazards of Combustion Products: Toxic cobalt oxide fumes may form in fire.
Профиль безопасности
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.
