Abstract
Methods of preparing titanated silica catalysts, and titanated silica catalysts. The titanated silica catalysts may include a silica support, which may include spherical beads. Methods of olefin epoxidation, which may include contacting an olefin with a titanated silica catalyst in the presence of an oxidant.
Claims18
A method of preparing a titanated silica catalyst, the method comprising:
- providing a liquid comprising (i) a water soluble organic compound, and (ii) a water soluble titanium compound, wherein the water soluble titanium compound is titanium(IV) bis(ammonium lactato)dihydroxide;
- and
- contacting a silica support with the liquid to deposit at least a portion of the water soluble titanium compound on the silica support to form a titanium-treated silica support.
