Description
Cobalt(II) Acetate Tetrahydrate Product Overview
Cobalt(II) acetate tetrahydrate (Co(CH3COO)2·4H2O) forms magenta-red crystals that dissolve easily in water, acetic acid and alcohols.
Its largest use is as a catalyst component in the liquid-phase oxidation of p-xylene to purified Terephthalic Acid, together with Manganese (II) Acetate 4-Hydrate and a bromide promoter. PET producers also add small amounts to give the polymer a neutral, slightly bluish tint. Paint and ink producers use cobalt salts as driers that speed up oxidative curing.
Other uses include catalyst preparation, anodizing sealants and cobalt compound synthesis. Cobalt acetate is classified in the EU as a carcinogen and reproductive toxicant, so it is supplied only for professional use. For other cobalt salts, see Cobalt(II) Nitrate Hexahydrate and Cobalt(II) oxide.
