Water → Cobalt lysocellin

Participants

Reaction Steps

A mixture of 13.0 g (0.02 mole) of sodium lysocellin and 2.5 g of cobalt acetate dihydrate in 150 ml of ethanol was stirred and held at ambient temperature for approximately 18 hours. Two volumes of water were added to the reaction mixture slowly. A tacky semi-solid precipitate formed. On continued stirring and trituration with fresh water, a filtrable solid was obtained. The removed cobalt salt was isolated and dried (13.1 g). The product had a melting point at 119.2° C. Analysis: Calculated % Co (4.48), Found (4.54).
