Preparation of soluble molybdenum catalysts for epoxidation of olefins
This patent describes the process of regenerating a soluble molybdenum composition to obtain a stable catalyst solution capable of being employed as a catalyst in the process for the epoxidation of an olefin with an organic hydroperoxide. Thermally precipitating and separating a molybdenum-containing solid contains up to about 50 percent by weight, of molybdenum from a spent catalyst solution derived from a molybdenum-catalyzed olefin epoxidation reaction. The molybdenum-containing solid has been contained by heating the spent catalyst solution with either solid solubilizating. The separated precipitated solid forms a soluble molybdenum composition by contacting at a temperature of between about 20/sup 0/C and about 130/sup 0/C, and removing any undesired solid material remaining with the solubilized molybdenum composition.
