Abstract:
1. A titanium-containing silicon oxide molded catalyst satisfying all of the following conditions (1) to (4): (1) an average pore diameter is 10 Å or more, (2) 90% or more of the whole pore volume have a pore diameter of 5 to 200 Å, (3) a specific pore volume is 0.2 cm (4) it is obtained by using, as a template, a quaternary ammonium ion of the following general formula (I) or an amine of the following general formula (II), then, removing the template, (in the formula (I), R 1 represents a linear or branched hydrocarbon group having 2 to 36 carbon atoms, and R 2 to R 4 represent an alkyl group having 1 to 6 carbon atoms), (in the formula (II), R 5 represents a linear or branched hydrocarbon group having 2 to 36 carbon atoms, and R 6 and R 7 represent hydrogen or an alkyl group having 1 to 6 carbon atoms).
