Description

Terephthalic acid (a portmanteau of the turpentine producing tree terebinthus, and phthalic acid) is the organic compound with formula C6H4(CO2H)2. This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. Several million tonnes are produced annually.
