Procedure

2,5 g. of cobalt acetate in 100 ml. of pyridine are treated with 69 g. of β-isophorone. The mixture is gassed with oxygen at 70° C. for 2 hours and subsequently worked up by distillation. The conversion of β-isophorone used amounts to 64 g. corresponding to 93%. Ketoisophorone is obtained in a yield of 48 g. corresponding to 68%.
