Polybutylene terephthalate (PBT) is an important, versatile thermoplastic polyester that has exceptional resistance to both heat and chemicals. It is non-flammable and crystallizes faster than normal polyethylene terephthalate (PET), giving it good injection molding properties. Due to its versatility and properties, it is used in a wide variety of applications in the electrical, electronic and automobile industries. The basic reaction is the formation of ester by the reaction of purified terephthalic acid (PTA) and alcohol 1, 4-Butanediol (BDO) in the synthesis of PBT (FIG. 1). The catalyzed reaction of carboxyl groups (COOH) from the PTA, with hydroxyl groups (OH) from the BDO, results in a
