Abstract Due to the harmful raw materials and difficulty of degradation, the engineering plastics produced by polyester would cause serious environmental problems and endanger the human health. Traditional polyester materials can not meet the increasingly stringent environment requirement. Therefore, we have to develop safe and environment-friendly alternative materials. The polyester synthesized using safe and green raw material (dimethyl 1,4-cyclohexanedicarboxylate (DMCD)) exhibiting excellent performance has been widely used in food packaging, children's toys, etc. DMCD is usually produced through catalytic hydrogenation of dimethyl terephthalate (DMT) in industry. The key and difficulty point of this process are the development of catalysts with high performance. At present, Pd, Ru, Rh and Ni catalysts are the most reported catalysts used for hydrogenation of DMT to DMCD. In this work, the research progress on the development of DMT hydrogenation catalysts was introduced. The effect of catalysts and the reaction conditions of synthesis of DMCD were systematically summarized. This paper may provide a reference for design and development of high activity catalysts for DMCD synthesis.
