ABSTRACT:
A process for making oxidized olefins is disclosed. Specifically, the process comprises providing an olefin and oxygen in combination in a reaction medium comprising carbon dioxide, and then oxidizing the olefin in the reaction medium to make the oxidized olefin. Preferably, a perfluoropolyether is produced by the process.
