US Patent 7910777 Method for producing cycloalkanol and/or cycloalkanone

The present invention provides 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;(2) the mesoporous silica having such pore distribution that 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 is 50% or more; and(3) the mesoporous silica being modified by an organic silicon compound.
