RECOVERY OF MOLYBDENUM FROM SPENT CATALYST SOLUTIONS FROM HYDROPEROXIDE EPOXIDATIONS Abstract Of The Disclosure In the process of recovering molybdenum from a spent catalyst solution obtained from a crude reaction product of a molybdenum catalyzed epoxidation of an olefin with an organic hydroperoxide from which crude reaction product epoxide and an alcohol corresponding to the hydroperoxide is removed, the improve- ment comprises removing and recovering dissolved molybdenum as a high molybdenum content solid by subjecting the spent catalyst solution to a liquid-to-liquid extraction with an aqueous extract to form a two phase system, separating the molybdenum aqueous extract and precipitating therefrom a high molybdenum content solid by heating the aqueous extract in the presence of hydrogen sulfide or a water soluble sulfide salt.
