Procedure

A mixture of 1380 g of a product obtained according to the hereinabove given process (β-phorone content: 51.6%) and 7 g of cobaltIII -acetylacetonate (Wacker Chemie GmbH, Munich, West Germany) was heated to about 50° under vigorous stirring (turbine speed: 1000 t/min). Air was then added to the said mixture at an initial flow of about 100-150 l/h, this flow being then progressively increased to about 300 l/h.
