ABSTRACT:
The process of regenerating a soluble, stable molybdenum-containing catalyst suitable 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 epoxidation of an olefin and solubilizing the precipitated solid by contacting with a liquid composition comprising an admixture of a monohydroxy alcohol, a polyhydroxy alcohol and an organic peroxide or hydroperoxide, said polyhydroxy alcohol being present in an amount of at least about 2 moles per mole or molybdenum to be solubilized.
