1,2,4-Benzenetricarboxylic anhydride Uses

  1,2,4-Benzenetricarboxylic anhydride (CAS NO.552-30-7) is used as an embossing agent for vinyl flooring and as a curing agent for epoxy resins. It is also used as an intermediate for the synthesis of surface coatings chemicals, polymers, dyes printing inks, adhesives, pharmaceuticals . It is mainly used as raw material for polyimide resin, polyester resin, plasticizer TOTM and also be used for producing heatproof & insulating, paint, adhesive,surfactant, synthesize dye materials etc.

1,2,4-Benzenetricarboxylic anhydride Production

1,2,4-trimethylbenzene as raw material, TRIMELLITIC ANHYDRIDE (552-30-7) is synthesized by liquid nitric acid oxidation or cobalt(manganese) catalytic air oxidation.

Chemical Properties    white crystalline powder,combustible.
Chemical Properties    Trimellitic anhydride is a crystalline solid. It is the anhydride of trimellitic acid (1,2,4-benzenetricarboxylic acid).
Uses    In the preparation of resins, adhesives, polymers, dyes, printing inks.
