Abstract:
1. A process for the preparative ozonolysis of unsaturated starting materials, comprising reacting unsaturated compounds selected from the group consisting of aliphatic C 4 -C 40 hydrocarbons, C 4 - C 40 monocarboxylic acids, esters of C 1 -C 10 alcohols or polyols with C 4 -C 40 monocarboxylic acids, C 4 -C 40 dicarboxylic acids, and esters of C 1 -C 10 alcohols or polyols with C 4 -C 40 dicarboxylic acids, with ozone in a microreaction system applied to a support, wherein said support comprises 10 to 1000 microreaction channels running parallel to one another, which channels may be actuated sequentially or simultaneously with the starting materials, to form ozonization products, wherein said unsaturated compounds contain 1 to 4 double bonds, and wherein said ozonization products are immediately subjected to oxidative cleavage by using an oxygen-containing gas stream, or, alternatively, to reductive cleavage by using a hydrogen-containing gas stream.
