1,2,4-Benzenetricarboxylic anhydride Usage And Synthesis

Chemical Properties white crystalline powder
Usage Trimellitic Anhydride is mainly used as raw material for polyester resin,polyimide resin,plasticizer TOTM ,and also be used for producing heatproof & insulating,adhesive,surfactant, paint,synthesize dye materials etc. Trimellitic anhydride 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, adhesives, polymers, dyes printing inks, pharmaceuticals . 
General Description Crystals or off-white flakes.
Air & Water Reactions Sensitive to moisture. Hydrolyzes slowly. Solutions in water or alcohol may be unstable. Insoluble in water.
Reactivity Profile 1,2,4-Benzenetricarboxylic anhydride reacts exothermically with water. This reaction is expected to be slow, but can become vigorous if local heating accelerates it. Reaction with water is accelerated by acids. Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases. Incompatible with strong oxidizing agents, strong acids or strong bases. .
Fire Hazard 1,2,4-Benzenetricarboxylic anhydride is combustible.
