Abstract: PROBLEM TO BE SOLVED: To provide a method for producing cyclohexanone oxime by a few processes in high conversion/productivity with small energy consumption under a mild reaction condition by a simple operation/facility. SOLUTION: This method for producing cyclohexanone oxime is characterized in that benzene is used as a starting raw material and production processes comprise (1) a process for partially hydrogenating (A) benzene in the presence of a catalyst (A) to give cyclohexene, (2) a process for nitrating cyclohexene to give nitrocyclohexene and (3) a process for partially hydrogenating (B) nitrocyclohexene in the presence of a catalyst (B) to give cyclohexanone oxime.

Abstract: PROBLEM TO BE SOLVED: To produce ε-caprolactam with an industrially advantageous simple method comprising small number of steps in high conversion of each step, high productivity and decreased energy consumption under a mild reaction condition with simple operation and equipment essentially without producing ammonium sulfate as a by-product while dispensing with a reaction reagent necessitating a complicate process for preparation. SOLUTION: ε-Caprolactam is produced by using benzene as a starting raw material and successively subjecting the material to partial hydrogenation, nitration, partial hydrogenation and vapor-phase rearrangement reaction.

Abstract: PROBLEM TO BE SOLVED: To provide a highly effective catalyst usable for oxidizing alcohols. SOLUTION: This method for producing an aldehyde or ketone is characterized by comprising oxidizing an alcohol in the presence of a palladium- immobilized hydroxyapatite obtained by immobilizing palladium on a hydroxyapatite represented by the general formula Ca10- Z(HPO4 )Z(PO4 )6- Z(OH)2- Z.nH2 O (wherein, Z is a number satisfying 0
