About Isophthalic Acid. Isophthalic Acid (a.k.a. PIA) is an aromatic dicarboxylic acid, isomer of phthalic acid and terephthalic acid. It appears as a stable, intractable solid with low solubility in most solvents. PIA is manufactured by oxidation of m-xylene, using a cobalt-manganese catalyst. It is used as precursor to commercially important polymers, in the production of resins for drink plastic bottles, in the high-performance polymer polybenzimidazole production process, and as an important input to produce insulation materials.
The Purified Isophthalic Acid is stored in powder form in silos. For transportation, dedicated hopper cars and trucks are used to ensure the extreme purity is maintained. Bags of 1 ton and paper bags of 25 kg are also used to carry out the transport. For large scale ocean shipping, plastic lined containers with a capacity of 20 tons of PIA are recommended.
Currently, virtually all commercial PIA is produced by oxidation of m-xylene with varying grades of purification. Raw materials and the respective production processes employed in the manufacturing of Isophthalic Acid are listed below.
- m-xylene + air (liquid-phase oxidation)
The uses and applications of Isophthalic Acid may vary according to its specification. The main forms of Isophthalic Acid are 82 wt% Isophthalic Acid and 98.5 wt% Isophthalic Acid.
Purified Isophthalic Acid is mostly used as a comonomer with terephthalic acid in bottle and specialty reins manufacturing. It is also applied as feedstock for coatings and high performance unsaturated polyesters.
