Abstract :

In this research, the chemical recycling of terephthalic acid from PET waste by using nanoFe3O4@Py-APTS as solid support was reported. The performance of organically modifiednano magnetic was examined in detail and the results were compared with unsupportedreactions as the model. By using the solid support, the required time for complete glycolysis,consumption of solvent and catalyst, decreased up 95 %, 37.5 % and 30 % respectively. Results showed that nano Fe3O4@Py-APTS delivered good performance as the reagent as well as the solid support in depolymerizing of PET to the terephthalic acid.
