A 50 ml solution of 29.1 g. of Co(NO3)2 · 6H20 (0.10 mole) and 10 ml of 30% hydrogen peroxide (excess) was added dropwise with stirring to a cold slurry of 42.0 g. of sodium bicarbonate(0.50 mole) in 50 ml of H20. The mixture was allowed to stand at 0 С for 1 hour with continuous stirring. The olive product was filtered, washed on the filter with three 10 cc portions of cold water, then thoroughly washed with absolute alcohol and dry ether; yield: 33.3 g., 92% of theoretical; 93 С dec.
