실험 절차

37.8 g of barium hydroxide octahydrate (0.12 mole) were placed in a 250 ml round-bottomed flask. 50 ml of 2,2,6,6-tetramethyl-3,5-heptane dione (0.24 mole) were added in drops via a dropping funnel. Then 70 ml of xylene were added. The reaction mixture was then heated to 50° C. by means of an oil bath and stirred at this temperature for 10 hours. Then the oil bath temperature was adjusted to 60° C. and volatile constituents were distilled off under high vacuum.
