Pellets of poly(ethylene terephthalate) (PET; 0.48-1.92 g) were heated in anhydrous ethylene glycol (EG; 5 mL) with 2-equivs of NaOH at 150ะŠC for 80 min or 180ะŠC for 15 min to convert them quantitatively to disodium terephthalate (Na 2 -TPA) and EG. The disodium salt was precipitated quantitatively
