ABSTRACT:
A process for converting a desired olefin to the corresponding olefin oxide, such as propylene oxide, and/or ketone comprising reacting a mixture of the olefin, thallic oxide, carbon dioxide and water in a substantially organic solvent-free reaction zone; withdrawing a product stream from the reaction zone, the stream comprising the olefin and ketone product; separating and collecting the olefin oxide and ketone product from the stream; contacting the reduced thallous values present in the mixture with molecular oxygen and an effective catalyst to back oxidize the thallous values to their original thallic form; separating and recycling back to the reaction mixture the regenerated thallic values.
