The effects of different temperatures on catalytic hydrolysis of polyethylene terephthalate(PET) by zinc sulfate as a catalyst under microwave irradiation were studied, and in the meantime, the relation between the depolymerization rate of PET and the yield of terephthalic acid(TPA) under the same temperature was investigated. The results suggested that the reaction temperature was an important influencing factor for the depolymerization reaction of PET, and the concentration of depolymerization product TPA and the depolymerization rate of PET became coherence under the same temperature.
