ABSTRACT:
The invention relates to a process for the preparation of monocarbonyl or biscarbonyl compounds by reacting organic carbon compounds having one or more olefinic or aromatic double bonds in the molecule with the equivalent amount of ozone and by subsequently catalytically hydrogenating the ozonization products, wherein the peroxide-containing ozonization solution is fed continuously into a suspension of the hydrogenation catalyst in a lower aliphatic alcohol, while a peroxide content of not more than 0.1 mole/l is maintained, and the ozonization products are continuously cleaved reductively to give the corresponding carbonyl compounds.
