Abstract: PET described in this paper on the importance of world and its negative impact. From chemical, biological, such as multi-angle list of methods used PET degradation. Focuses on the alkaline hydrolysis degradation of PET. PET in NaOH or-catalyzed hydrolysis of terephthalic acid and diol in pairs,, The mixture heated to 340 ℃ evaporation by distillation method of recovery has been diol. Quantitative analysis of alkali concentration, temperature and time conditions on the degradation of PET, the optimal conditions.
