RECOVERY OF MOLYBDENUM AS AN AQUEOUS SOLUTION |
摘要 |
<p>80-PD-16 RECOVERY OF MOLYBDENUM AS AN AQUEOUS SOLUTION 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 exaction 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.</p> |
