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 ¡æ 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.
