Abstract:
1. A method for producing cycloalkanol and/or cycloalkanone, which comprises reacting cycloalkane with molecular oxygen in the presence of mesoporous silica, (1) the mesoporous silica containing at least one transition metal selected from the group consisting of vanadium, chromium, manganese, cobalt, ruthenium, and palladium; (2) the mesoporous silica having pore distribution with the ratio of a total pore volume of mesoporous silica particles having a pore size of 3 to 50 nm to a total pore volume of mesoporous silica particles having a pore size of 2 to 50 nm being 50% or more; and (3) the mesoporous silica being modified by an organic silicon compound, and wherein the mesoporous silica is obtained by the steps of performing a hydrothermal synthesis reaction with a mixture containing tetraalkoxysilane, polyalkylene oxide and water to obtain a mesoporous silica, calcining the mesoporous silica, bringing the mesoporous silica in contact with a transition metal compound to produce a mesoporous silica-containing transition metal, and then treating the resulting mesoporous silica with an organic silicon compound of formula (I): wherein R
