A titanium-containing silicon oxide molded catalyst satisfying all of the following conditions (1) to (4): n (1) an average pore diameter is 10 Å or more, n (2) 90% or more of the whole pore volume have pore diameters of 5 to 200 Å, n (3) a specific pore volume is 0.2 cm 3 /g or more, and n (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. n [NR 1 R 2 R 3 R 4 ] + (I) n (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.) n NR 5 R 6 R 7 (II) n (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.). |
