Isophthalic Acid

TECHNOLOGY FOR THE PRODUCTION OF ISOPHTHALIC ACID

Isophthalic Acid (Benzene - 1,3–Dicarboxylic acid) is an aromatic di-carboxylic acid industrially produced by the oxidation of m-xylene.

It is used as a component of PET (poly-ethylene terephthalate), which is mainly used to produce plastic bottles for drinks, films, and food packaging.
Isophthalic acid reduces the crystallinity of PET, increasing its operability and improving its clearness.

Isophthalic acid is a component of high-quality alkyds and polyester resins for coatings and unsaturated polyesters for fiberglass-reinforced plastics applications.

CONSER can offer technology of production of Isophthalic acid either based on low-temperature oxidation reaction (activated by aldehyde) or on high-temperature oxidation reaction (activated by bromine).
