The experimental conditions for hydrolysis of polyethylene terephthalate(PET)catalyzed by carbonates was optimized by the orthogonal test. The main influence factors of PET microwave hydrolysis reaction were confirmed as the reaction temperature, time, and catalyst dosage. And their effect on catalytic microwave hydrolysis of PET was studied. The results show that the sequence of influence factors is as follows: reaction temperature>reaction time> catalyst dosage. The optimal experimental conditions under t...
