PURPOSE:To obtain the titled compound which is an intermediate for solvents, perfumes, etc. in a high space-time yield, per-pass yield and selectivity, by using easy unit operations to bring cyclopentanol into contact with a palladium catalyst having improved durability. CONSTITUTION:Cyclopentanol is brought into contact with a catalyst and dehydrogenated to give cyclopentanone. In the process, a palladium catalyst is used as a catalyst to carry out the reaction at 150-400 deg.C and 0.2-5kg/cm<2>. A catalyst prepared by supporting palladium ions or palladium amine complex, etc. on a carrier, e.g. silica, alumina or silica alumina, by the ion exchange or ligand exchange method is suitable for preparing the cyclopentanone in large amounts with a small amount of the palladium. USE:An intermediate for chemicals. |
