Melting point: 207 °C (405 °F; 480 K) Solubility in water. The main industrial uses of purified isophthalic acid (PIA) are for the production of polyethylene terephthalate (PET) resin and for the production of unsaturated polyester resin (UPR) and other types of coating resins. Phthalic acid is an aromatic dicarboxylic acid, with formula C 6 H 4 (CO 2 H) 2.It is an isomer of isophthalic acid and terephthalic acid.Although phthalic acid is of modest commercial importance, the closely related derivative phthalic anhydride is a commodity chemical produced on a large scale. This "neutralization" generates substantial amounts of heat and produces water plus a salt. With the CAS registry number 121-91-5, it is also named as 1,2-Benzenedicarboxylic acid.
