Patent ID: 7923583

Claim:
A method for producing a cycloalkanol and/or a cycloalkanone, which comprises oxidizing a cycloalkane with molecular oxygen in the presence of a mesoporous silica which contains at least one transition metal, wherein the mesoporous silica is prepared by mixing a compound containing the transition metal, a silicon compound, a structure-directing agent and water to obtain a crystal, subjecting the crystal to contact treatment with an amine and/or ammonia, and then firing the resultant, and subjecting the fired resultant to contact treatment with an organosilicon compound represented by the formula (1): Si(R 1 ) x (R 2 ) 4−x (1) wherein R 1 represents an alkoxy group, a hydroxy group or a halogen atom, R 2 represents an alkoxy group, an alkyl group, an allyl group, an aryl group or an aralkyl group, and x represents a number of 1 to 3.
