Procedure

Four grams (0.1 mol) of sodium hydroxide were dissolved in 150 cc of water. To this solution, 14.2 g (0.1 mol) of 2,4-octanedione were added slowly while stirring. After the dissolution had been completed, the obtained solution was dripped taking 10 minutes while vigorously stirring into a cobalt (II) chloride aqueous solution which had been prepared in advance by dissolving 11.9 g (0.05 mol) of hexahydrated cobalt (II) chloride in 200 cc of water. The produced rose-red-colored precipitate was separated by filtration and washed with water until the washing water became substantially colorless, followed by vacuum drying to obtain 15.1 g of the object: 2,4-octanedione cobalt complex.
