• 用途

  化学物質製造段階の触媒

• 用途

  他のコバルト塩と同様、ガラスや陶磁器の彩色用顔料となる他、電池や電気めっき、不可視インク原料としての用途もある。ミネラル補給目的で、飼料に添加される。かつては泡の安定を目的としてビールに添加されたり、貧血の治療薬としても用いられた。

• 説明

  The blue, crystalline hydrate Co2(SO4)3.18H2O is prepared by the oxidation of cobalt(II) sulphate in 8N sulphuric acid either electrolytically or chemically with ozone or fluorine. It is stable in the dry state, but is decomposed by water with evolution of oxygen; it is fairly stable in solution in dilute sulphuric acid. Cobalt(III) alums MCo(SO4)2.12H2O (M = K, Rb, Cs or NH4) can be isolated as blue crystals from the mixed cooler solutions of the two sulphates in dilute sulphuric acid. The potassium alum is diamagnetic, the rubidium salt has a magnetic moment less than 1 B.M. and the ammonium alum has a moment of 2.1 B.M. at 304°K. The hydrated sulphate also has a small positive magnetic susceptibility. The sulphate is believed like the alums to contain the [Co(H2O)6]3+ ion.

• 化学的特性

  Red powder or rose pink crystalline solid. Odorless.

• 使用

  Ceramics, pigments, glazes, in plating baths for cobalt, additive to soils, catalyst, paint and ink drier, storage batteries.

• 一般的な説明

  Odorless rose-pink solid. Sinks and mixes with water.

• 空気と水の反応

  Water soluble.

• 反応プロフィール

  Acidic salts, such as Cobalt sulfate , 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.

• 危険性

  May not be used in food products (FDA). Possible carcinogen.

• 健康ハザード

  Inhalation causes shortness of breath and coughing; permanent disability may occur. Ingestion causes pain and vomiting. Contact with eyes or skin causes irritation.

• 火災危険

  Special Hazards of Combustion Products: Toxic cobalt oxide fumes may form in fire.

• 安全性プロファイル

  Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. Questionable carcinogen. When heated to decomposition it emits toxic fumes of SOx See also COBALT COMPOUNDS.

• 職業ばく露

  Many be used to catalyze organic reactions.

• 発がん性

  Cobalt sulfate is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.

• 輸送方法

  UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

• 純化方法

  Crystallise it three times from conductivity water (1.3mL/g) between 100o and 0o depending on which hydrate is required. The heptahydrate crystallises below 44o and is efflorescent with m 97o . Between 44o and 70o the monoclinic hexahydrate CoSO4.6H2O m 41.5o is formed, and above 70o the monohydrate CoSO4.H2O m 71o is obtained. The pale reddish or lavender-coloured anhydrous salt is obtained by heating the hydrate above 250o, boiling with conc H2SO4 or heating with (NH4)2SO4).

• 不和合性

  Aqueous solution reacts with bases, generating some heat. May react as either oxidizing agents or reducing agents

• 廃棄物の処理

  Use a licensed professional waste disposal service to dispose of this material. All federal, state, and local environmental regulations must be observed.
