Poly(ethylene terephthalate) (PET) is a thermoplastic polyester which is produced by polycondensation of ethylene glycol (EG) and terephthalic acid (TPA).Various parameters are effective on PET synthesis as type of catalyst, catalyst concentration, paste mixing temprature, esterification temprature, esterification pressure, esterification mixing rate, esterification time, polycondensation tempture, polycondensation pressture and …
In this research, PET synthesis is studied in the presence of different catalysts such as antimony trioxide (Sb2O3) and titanium tetrabutoxide (TBT) under the same experimental conditions. The effect of various monomer feed ratio (EG/TPA) and pressure of esterification step on the intrinsic viscosity (IV) of final produced PET has been investigated. The results have shown that the monomer feed ratio in the range of 1.7 to 1.9 for TBT catalyst and 1.5 to 1.7 for Sb2O3 catalyst and the pressure in the range of 4 to 4.5 (bar) for both of them, increase the intrinsic viscosity of the PET.
