Terephalic acid condenses with ethylene glycol to give polyethylene terephthalate ester (PET). The temperature in increased from 150 to 270°C and excess ethylene glycol distilled off.

The use of the PET was held back for may years due to purity problems with acid, however, these have been overcome and PET is now used for disposable items such as clear plastic bottles.
