Terephthalic acid CAS#100-21-0

Basic Information

Terephthalic acid
white powdery crystal

Terephthalic acid is a white, odorless powdery crystal that is barely soluble in water and only slightly soluble in selected organic solvents. Its stable carboxylic-acid structure supports esterification and polycondensation with alcohols. It is a core raw material for polyester chips, fibers, films, resins, bottles, packaging, coatings, plastic products, and chemical-fiber textiles.
