Fire HazardsNot combustible. Gives off irritating or toxic fumes (or gases) in a fire.

Hazards SummaryA skin, eye, and respiratory tract irritant; May cause skin sensitization; [ICSC] Harmful if swallowed; May cause skin and respiratory tract sensitization; [MSDSonline] See Cobalt.

Chemical DangersDecomposes on heating. This produces irritating fumes. Reacts with strong oxidants. This generates fire and explosion hazard.

Packaging and LabellingDo not transport with food and feedstuffs.

安全と保護具

Fire FightingIn case of fire in the surroundings, use appropriate extinguishing media.

First Aid Measures · 4 件

Fresh air, rest. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower. Seek medical attention if you feel unwell.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

使用Cobalt(II) acetate tetrahydrate is used to prepare complexes for examination of the properties of metals with unusual coordination geometries. used as a catalyst for oxidation and esterification. used as an industrial catalyst to harden paints and varnishes, an active catalyst for oxidation and esterification reactions.

一般的な説明Cobalt(II) acetate tetrahydrate has an octahedral structure, the central cobalt orbit is coordinated by four water molecules and two acetate ligands. Cobalt(II) acetate tetrahydrate becomes anhydrous by 140oC.

調製方法

純化方法Several recrystallisations from 50% aqueous acetic acid give the tetrahydrate. It is converted to the anhydrous salt by drying at 80o/1mm for 60hours. [Beilstein 2 IV 120.]
