Abstract

A process of increasing reaction rate of Polyethylene terephthalate (PET), which is characterized in that during the production of PET, the Sb2O3 catalyst is pre-treated in ethylene glycol with appropriate amount of BHET, esterification product of terephthalic acid and ethylene glycol, at a temperature (110-350 deg.C) which will not destroy structure of BHET and ethylene glycol; the pre-treated solution is subsequently used as the catalyst to undergo polycondensation reaction in which during thepre-treatment 0.005~50 grams of BHET was added per gram of Sb2O3.
