An improved process for the safe ozonolysis of unsaturated, organic carbon compounds having one or more olefinic or aromatic double bonds in the molecule in flammable solvents for the preparation of mono- or biscarbonyl or hydroxy compounds, in which ozonolysis is carried out with the use of an ozone-carrying inert gas/O2 stream, in which the oxygen concentration in the inert gas/O2 stream is above the known limiting oxygen concentration of the homogeneous fuel/gas mixtures and below the safety-critical limiting oxygen concentration of the heterogeneous mixture of the liquid fuel and oxygen-containing gas which is dependent on the reaction conditions and at which ignition and flame propagation no longer take place. |
