Preparation of soluble molybdenum catalysts for epoxidation of olefins.

摘要

The process of regenerating soluble molybdenum catalyst for epoxidation of olefins with a hydroperoxide which comprises thermally precipitating and separating a molybdenum-containing solid obtained from a spent catalyst stream derived from a molybdenum catalyzed olefin epoxidation, and solubilizing the precipitation solid by heating with a liquid hydroxyl-containing organic compound to produce an active catalyst solution.
