    Abstract: In the process of epoxidation of an olefinic compound with an organic hydroperoxide catalyzed by a liquid solution of dissolved molybdenum wherein the crude epoxidation reaction mixture is separated into product components including a product epoxide, an alcohol corresponding to the hydroperoxide reactant and a spent catalyst solution, and wherein said spent catalyst solution is treated by

    a) extracting molybdenum values from the spent catalyst solution by a liquid-to-liquid extraction with an extracting medium consisting essentially of water or water and a water immiscible organic solvent,
    b) separating the molybdenum-rich aqueous phase,
    c) removing water and lower boiling organic compounds from the separated aqueous phase extract and recovering a concentrated molybdenum solution,

    wherein the improvement comprises introducing the concentrated molybdenum solution of c) into a mixture of an olefin and a hydroperoxide to catalyze the epoxidation of the olefin.

    Abstract: The process of separating components of a crude reaction mixture obtained from a molybdenum-catalyzed hydroperoxide epoxidation of an olefin wherein the product epoxide and an alcohol corresponding to the hydroperoxide used are removed from the reaction mixture leaving a spent catalyst solution and subjecting the spent catalyst solution to a liquid-to-liquid solvent extraction to separate dissolved molybdenum values, is improved by solvent extracting the spent catalyst solution with an extracting medium consisting essentially of water and a water immiscible organic solvent to form a two phase system and then separating the molybdenum-rich aqueous phase extract from the organic phase extract. The molybdenum-rich aqueous phase extract may be treated to recover the molybdenum as a solid or the extract may be treated to obtain an active molybdenum catalyst suitable for reuse as a catalyst in a hydroperoxide epoxidation reaction.
