Trimellitic anhydride Uses
Trimellitic anhydride is used to manufacture polyester resin and polyimide resin, water-soluble
polyester resin, plasticizer and water-soluble amino alkyd resin, water-soluble polyurethane resin,
epoxy resin curing agent, advanced aviation lubricating oil, power capacitor impregnating oil,
sizing agent, smoke suppressant, granular binder, instant binder and TOTM, etc.

The active chemical properties of partial anhydride make it an important raw material for organic synthesis, which can synthesize many high value-added environmentally friendly fine chemical products and has a wide range of applications [2]:

(1) Trimellitic acid ester plasticizers synthesized through esterification reaction of partial anhydrides and monohydric alcohols have excellent electrothermal properties and are widely used as heat-resistant and environmentally friendly plasticizers for polyvinyl chloride (PVC), such as heat-resistant plasticizers. Wire and cable materials with grades of 90ºC and 105ºC and high voltage 6kV and 10kV.

(2) The polymerization reaction of partial anhydride and phenyl diisocyanate produces polyamide-imide polymer, which has the advantages of good high temperature environment performance, resistance to solvent dissolution, good impact resistance, good radiation resistance and creep resistance. , widely used in trough equipment for motors and insulating paint for wires and cables.

(3) Alkyd resin materials have excellent stability and are often used in electrophoretic coating primers. The fire resistance time and flame propagation ratio indicators of this alkyd resin material both meet the first-class standards.

(4) Polyester resin can be produced by first synthesizing polyester resin using partial anhydride as raw material, and then mixing it with epoxy resin according to a certain formula. The powder can also be melted to form a film, which has the advantages of environmental protection and construction.

(5) Block polymer rubber synthesized using partial anhydride as raw material has good weather resistance, flexibility and light stability; partial anhydride can be produced by reacting partial anhydride with higher fatty alcohols such as dodecyl alcohol and stearyl alcohol. Tricarboxylic acid ester sodium salt is an excellent anionic surfactant.
