Abstract:
1. A process for producing a titanium-containing silicon oxide catalyst satisfying all of the following conditions (1) to (3), which comprises the following A and B steps: (1) an average pore diameter of 10 Å or more, (2) a pore diameter of 90% or more of the total pore volume of 5 to 200 Å, and (3) a specific pore volume of 0.2 cm step A: (I) a step of obtaining a solid containing a catalyst component and a template by using a silicon compound in which a part or all of a hydrocarbon group is directly bonded to a silicon atom, as a silica source, and mixing the silica source with a titanium source and a solution of the template by stirring, wherein the rate of water in a solvent in the solution is 5 to 40% by weight, or (II) a step of obtaining a solid containing a catalyst component and a template by using an organic silica source composed of a silicon compound in which a hydrocarbon group is directly bonded to a silicon atom and an inorganic silicon source composed of a silicon compound not having a carbon-silicon bonding, as a silica source, and mixing the silica source with a titanium source and a solution of the template by stirring, wherein the following expression is satisfied in the addition of the silica source to the solution of the template, Amount of the organic silicon compound added in the first half>Amount of the organic silicon compound added in the latter half, wherein the first half means a period taken from the initiation of the addition to completion of the addition of the half mole of the amount of the total silica source; and Step B: a step of removing the template from the solid obtained in the step A.
