ABSTRACT:
A process for producing a titanium-containing silicon oxide catalyst having a silicon-carbon-silicon bond, silicon-oxygen-silicon bond and silicon-oxygen-titanium bond which includes causing a silicon compound of the following formula (1) and a titanium alkoxide compound to gel in a water and/or alcohol solvent and removing the solvent in the resulted gel by extraction with a supercritical fluid(R1to R7each independently represent a hydrocarbon group having 1 to 20 carbon atoms.).
