Process for the recovery of molybdenum from an organic solution, such as a spent catalyst solution obtained from the molybdenum catalyzed epoxidation of an olefinically unsaturated organic compound with an organic hydroperoxide as oxidizing agent and removal from the crude epoxidation mixture of product epoxide and the alcohol corresponding to the hydroperoxide, said process comprising: admixing the organic solution with water in an amount between about 0.5 and 10 percent, based on the weight of the organic solution; heating the resultant admixture to a temperature in the range of between about 150/sup 0/C and 250/sup 0/C under pressure sufficient to maintain the admixture in the liquid phase and for a time sufficient to precipitate at least a portion of the molybdenum contained in the organic solution as a solid; and separating the precipitated molybdenum containing solid from the organic solution.
