Trimellitic anhydride is a white solid in the form of flakes. It is readily hydrolysed in water to trimellitic acid, which is moderately soluble in water. Trimellitic anhydride is readily soluble in acetone, cyclohexanone, 2-butane, ethyl acetate, and dimethyl formamide (from 49.6 to 15.5% w/w at 25 °C).
1. Trimellitic anhydride is used in the production of resins for electrode-position and powder coatings, and as a binder for glass fibers, and other aggregates.
2. Trimellitic anhydride is used as an embossing agent for vinyl flooring and as a curing agent for epoxy resins.
3. It is also used as an intermediate for the synthesis of surface coatings chemicals, adhesives, polymers, dyes printing inks, Pharmaceuticals and agrochemicals.
