METHOD FOR PREPARING 1,4-CYCLOHEXANEDIMETHANOL

摘要

The present invention relates to a method for preparing 1,4-cyclohexanedimethanol, comprising the steps of: reducing terephthalic acid in the presence of a first metal catalyst comprising a palladium (Pd) compound fixed to a dealuminated zeolite support; and reducing the reduced product of terephthalic acid in the presence of a second metal catalyst comprising, in a ratio of 1:0.8-1.2:0.2-0.6 on the basis of metal weight, a ruthenium (Ru) compound, a tin (Sn) compound and a platinum (Pt) compound fixed to a dealuminated zeolite support.
