ABSTRACT:
The process of regenerating a stable organic soluble 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 a peroxy compound, a monohydroxy alcohol, optionally a polyhydroxy alcohol, and an organic dicarboxylic acid present in an amount of at least about 0.2 parts, by weight, of molybdenum contained in said solid.
