Trimellitic Anhydride (TMA)

TECHNOLOGY FOR THE PRODUCTION OF TRIMELLITIC ANHYDRIDE (TMA)

Trimellitic Anhydride (1,3–Dihydro-1,3 Dioxo–5–Iso-benzofurancarboxylic acid, TMA) is a very reactive chemical of relatively low molecular mass.
Many of its industrial uses depend on the reactivity of the anhydride group.
It is mainly used in the synthesis of trimellitate esters, used as plasticizers of PVC and other various synthetic resins, especially when temperature and water stability are required.

Other TMA applications include:

• - Adhesives
• - Solvent-borne and waterborne coatings
• - Powder coatings
• - Binder for aggregates
• - Curing agent for epoxy and other resins
• - Paints

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).
