Bis(2-hydroxyethyl)terephthalate is formed as an intermediate in the manufacture of poly(ethylene terephthalate) through the esterification of terephthalic acid to form bishydroxyethyl terephthalate which is then polymerized in a transesterification reaction catalyzed by antimony oxide to form poly(ethylene terephthalate).
