Abstract

Glycolysis of recycled polyethylene terephthalate (PET) from post-consumer soft-drink bottles was carried out with ethylene glycol (EG) at different weight ratios of PET to EG using zinc acetate as catalyst at the boiling point of EG under nitrogen atmosphere for a constant time of 8 h. The results showed that in excess of EG (at mole ratio of PET/EG = 0.12) the glycolyzed products contained predominantly bis(hydroxyethyl) terephthalate (BHET). Kinetics of polyesterification of glycolyzed product, BHET, made from a mole ratio of 0.12 of PET/EG with maleic anhydride was also studied without using acid catalyst. The polyesterification was carried out at different temperatures (135, 160, 200 and 210 °C) comparable to the industrial process scheme. It was observed that the acid value of the reaction mixture decreased and the extent of reaction increased sharply with increasing temperature or time of the reaction. At 135 °C the kinetic plots, using third-order kinetics, were non-linear at initial times.
