Terephthalic Acid Analysis Service

Terephthalic acid (1,4-Dicarboxybenzene) is a key organic compound widely used in the production of polyester fibers, plastics, coatings, and other industrial materials. Its structure, with two carboxyl groups positioned at opposite ends of a benzene ring, makes it an essential precursor for polyethylene terephthalate (PET) and other polymeric materials. As demand for PET increases, terephthalic acid has become a critical component in the global chemical industry.

Although both terephthalic acid and phthalic acid are dicarboxylic acids, they differ significantly in their chemical behavior and applications. Terephthalic acid's para-positioned carboxyl groups are ideal for producing linear polyesters, while phthalic acid, with its ortho-positioned carboxyl groups, is mainly used in plasticizers. Thus, precise analysis of terephthalic acid is essential to ensure high product quality and process consistency.
