Abstract
The invention pertains to a process for oxidizing unsaturated starting materials, comprising: (i) providing a liquid composition containing an olefin and/or aromatic starting compound, (ii) compressing an ozone-containing gas to a pressure of at least 5 bar absolute, (iii) introducing the compressed ozone-containing gas in one or more microreactors, bringing said gas into contact with said liquid composition (i), to obtain an ozonide, (iv) and optionally subjecting said ozonide to oxidative or reductive degradation. The use of compressed ozone makes it possible to mix large gas volumes with small liquid volumes, and achieve satisfactory contact between the gas and liquid reactants. This dramatically improves yields over conventional micro-reactor-driven ozonolysis.
