Literature References: Prepd by electrolytic oxidation of Co(C2H3O2)2.4H2O in glacial acetic acid contg 2% (v/v) water: Sharp, White, J. Chem. Soc. 1952, 110; by oxidation of solns of cobaltous salts by alkaline persulfates in the presence of acetic acid: Peschanski, Wormser, Compt. Rend. 252, 1607 (1961). Generally considered to be a hydroxo-bridged binuclear complex.
Properties: Dark-green, very hygroscopic powder or green octahedral crystals. Becomes black and dec on heating to 100°. Sol in water, acetic acid, alcohol, n-butanol; dec by mineral acids. Aq solns hydrolyze slowly at room temp, rapidly at 60-70°; reduced by light or FeSO4.
Use: Catalyst for cumene hydroperoxide decompn.
