Using ionic liquid as catalyst, ethylene diamine, aniline, ethanolamine amine as the solvent, under certain conditions, degradation of waste polyethylene terephthalate (PET). Results showed that, the degradation effect of ethylenediamine is obvious, has the advantages of can be performed at low temperature, but also in the presence of monomer separation difficult problem; aniline degradation of PET, at each temperature were unable to reach the purpose of degradation; ethanolamine degradation of PET required reaction temperature is higher than that of Ethylenediamine, but its advantages as monomer purity and easy separation the catalyst is easy to extract, and can be used repeatedly. In summary, ethanolamine as ideal solvents amine solution degradation PET.
