  • Recovery of molybdenum
    Patent number: 4405572
    Abstract: Molybdenum catalyst employed in the epoxidation of an olefin with an organic hydroperoxide preferably the epoxidation of propylene, is recovered from the bottoms fraction by adding aqueous alkaline material to the bottoms fraction and separating the aqueous phase. The molybdenum can be recovered from the aqueous phase by acidification and precipitating it as an insoluble compound.
