Abstract
A method of preparing a catalyst comprising a) contacting a titanium-containing compound, a solvating agent, and a solvent to form a solution; b) contacting the solution with a chrominated silica-support to form a pre-catalyst; and c) thermally treating the pre-catalyst by heating to a temperature of from about 400° C. to about 1000° C. for a time period of from about 1 minute to about 24 hours to form the catalyst.
Claims24
A method of preparing a catalyst comprising:
- a) contacting a titanium-containing compound, a solvating agent, and a solvent to form a solution, wherein the solvating agent comprises a β-hydroxy-α,β-unsaturated carbonyl-containing compound, an α,β-dihydroxy-α,β-unsaturated carbonyl-containing compound, or a combination thereof;
- b) contacting the solution with a chrominated silica-support to form a pre-catalyst;
- and
- c) thermally treating the pre-catalyst by heating to a temperature of from about 400° C. to about 1000° C. for a time period of from about 1 minute to about 24 hours to form the catalyst.
