Description and 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.
