Abstract
A process for reducing the loading of wastewaters produced in the preparation of hydroxyl and carbonyl compounds from hydroperoxides by the Hock process, which may be acidic, by treating the wastewaters with an oxygen-containing gas at a pressure greater than 25 bar absolute and at a temperature of 150-250° C. Surprisingly, improved degradation rates are achieved under these conditions.
