More Information
Summary:Disclosed are a composite metal catalyst composition capable of increasing efficiency and economic feasibility of a reaction through simplification of a reaction process, and providing 1,4-cyclohexanedimethanol with high purity for a shorter time while minimizing byproducts; and a method and apparatus for preparing 1,4-cyclohexanedimethanol with high purity using the same. The present invention provides a composite metal catalyst composition for converting an aromatic dicarboxylic acid into an alicyclic diol compound, the composition containing: a first metal catalyst including a palladium (Pd) compound; and a second metal catalyst including a ruthenium (Ru) compound, a tin (Sn) compound, and a platinum (Pt) compound, and a method and apparatus for preparing 1,4-cyclohexanedimethanol using the same.
