코발트(II) 브로마이드 C화학적 특성, 용도, 생산
화학적 성질
Reddish violet crystalline powder용도
Cobalt(II) bromide is used as a catalyst in organic synthesis. It is used as a precursor in the production of ethylsulfanyl)porphyrazinato)cobalt(II), which gives the possibility of intermolecular ferromagnetic interactions.제조 방법
Cobalt(II) bromide (CoBr2) is on its anhydrous form a green solid that is soluble in water, used primarily as a catalyst in some processes. Cobalt(II) bromide can be formed as a hydrate by the reaction of cobalt hydroxide with hydrobromic acid.Co (OH) 2 (s)+2HBr (aq)→CoBr2.6H2O(aq)
일반 설명
COBALT(II) BROMIDE is a red violet crystalline solid. COBALT(II) BROMIDE is soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. COBALT(II) BROMIDE is used as a catalyst in the production of other chemicals.공기와 물의 반응
Water soluble.반응 프로필
Acidic salts, such as COBALT(II) BROMIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. When heated to decomposition can give off highly toxic fumes of Br [USCG, 1999].건강위험
SOLID: Irritating to skin and eyes. Harmful if swallowed.화재위험
Not flammable. POISONOUS FUMES ARE PRODUCED WHEN HEATED TO DECOMPOSITION. When heated to decomposition can give off highly toxic fumes of Br.Purification Methods
Crystallise it from water (1mL/g) by partial evaporation in a desiccator. The anhydrous salt is soluble in EtOH, Me2CO, MeOAc to form blue-coloured solutions. [Glemser in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1517 1965.]코발트(II) 브로마이드 준비 용품 및 원자재
