Procedure
A cobalt solution was obtained by dissolving cobalt acetate tetrahydrate (CoAc.4H2O, 4 g) in ethylene glycol (36 g) to produce a cobalt glycolate solution containing 10% cobalt acetate tetrahydrate. After stirring for 60 minutes, large particles dissolved, it became uniform red purple solution. A portion (9 g) of the cobalt acetate tetrahydrate solution and 1 g of a phosphoric acid solution (10% H3PO4 in ethylene glycol) were mixed in an open glass beaker. After shaking, flocculates in dark bluish purple formed in the bottom of the glass beaker. After 10 days, top 3 ml was red liquid mainly ethylene glycol, bottom 7 ml was dark purple flocculates.
