The potential environmental benefits of change are clear. Terephthalic acid (para-Phthalic acid, 1,4-Benzenedioic acid), a raw material for polyethylene terephthalate (PET) production, is one of the most important chemicals in petrochemical industry. Process for Preparation of Terephthalic Acid . Purified terephthalic acid (PTA) is derived in a white physical form or crystalline powder and is inert in nature. Purified Terephthalic Acid-PTA comes in the form of white crystals or powder. It is an important monomer in the production of high impact resistance, thermal stability and weather resistance resins such as the polyesters PET and PBT. This study presents the Purified Terephthalic Acid production, revenue, market share and growth rate for each key company, and also covers the breakdown data (production, consumption, revenue and market share) by regions, type and applications. or. contg. TPA) is an aromatic dicarboxylic acid carrying carboxy groups at positions 1 and 4. Purified terephthalic acid (PTA) is the important feedstock in production of polyester. For example, terephthalic acid (TPA), a building block in the production of polyester polymers, is generally commercially produced by the liquid phase partial oxidation of paraxylene (p-xylene) with an oxygen-containing gas using an aliphatic acid, such as glacial acetic acid, as the solvent, and a catalyst which is highly selective for the production of terephthalic acid. 5.1. The reaction is exothermic, producing water which is removed in a solvent recovery system.
