Disclosed is a process for a cyclohexanedimethanol by hydrogenation of a cyclohexanedicarboxylate ester in the presence of a Raney metal catalyst doped with rhenium. The process is useful for the preparation of 1,4-cyclohexanedimethanol from dialkyl esters of 1,4-cyclohexanedicarboxylate or dialkyl terephthalates. When Raney nickel is used as the catalyst, the process produces CHDM having a high trans content. |
