US 7,923,583 B2 · Method for producing cycloalkanol and/or cycloalkanone

Abstract

An object of the present invention is to provide a method capable of producing a cycloalkanol and/or a cycloalkanone with a favorable selectivity coefficient by oxidizing a cycloalkane with a favorable conversion ratio. Disclosed is a method for producing a cycloalkanol and/or a cycloalkanone, which comprises oxidizing a cycloalkane with oxygen in the presence of a mesoporous silica which contains at least one transition metal and has been also subjected to contact treatment with an amine and/or ammonia. Preferably, a crystal obtained by mixing a compound containing the metal, a silicon compound, a structure-directing agent and water is subjected to contact treatment with an amine and/or ammonia and then fired to obtain a mesoporous silica, and a cycloalkane is oxidized with oxygen in the presence of the mesoporous silica.

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(R1)x(R2)4−x (1)
wherein R1 represents an alkoxy group, a hydroxy group or a halogen atom, R2 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.
