Abstract

Poly(ethylene terephthalate) waste materials were depolymerized by ethylene glycol (EG), diethylene glycol (DEC), and propylene glycol (PG) in the presence of a novel catalytic system: titanium (IV)-phosphate. The new catalyst was synthesized through a reaction of TiCl₄ with triethyl phosphate (C₂H₅O)₃P(O). It was found that the depolymerization of poly(ethylene terephthalate) fiber proceeds faster in the presence of titanium (IV)-phosphate compared with compounds traditionally used in this process like Zn(OOCCH₃)₂. The oligomer distribution in the glycolysis products was studied by, size-exclusion chromatography.
