Overview of Terephthalic Acid

Terephthalic Acid is a key aromatic dicarboxylic acid extensively used in the manufacture of polyester resins, PET plastics, fibres, films, and speciality industrial chemicals. Chemically, its molecular formula is C₈H₆O₄, and the terephthalic acid IUPAC name is benzene-1,4-dicarboxylic acid. It is produced through the oxidation of para-xylene under controlled industrial conditions.

In appearance, Terephthalic Acid is a white crystalline powder with high purity requirements for polymer-grade applications. The terephthalic acid molecular weight is 166.13 g/mol. It exhibits a high terephthalic acid melting point of approximately 427 °C (sublimes) and does not have a conventional terephthalic acid boiling point, as it decomposes before boiling. The terephthalic acid structure—with para-positioned carboxyl groups—enables efficient polymerisation and high-strength polyester formation.
