Molecular formula: C9H4O5
Relative molecular mass: 192.13
Structural formula:
1. Performance and use:
Trimellitic anhydride is a white powder or flakes. It is the anhydride of trimellitic acid (1,2,4-benzenetricarboxylic acid). It is soluble in water, ethanol, acetone and other general organic solvents.
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.
Trimellitic anhydride is also used as an intermediate for the synthesis of surface coatings chemicals, adhesives, polymers, dyes printing inks, pharmaceuticals .
Trimellitic anhydride is mainly applied to produce good heat-proof, weather-proof and solvent-proof trimellitate plasticizers, among which the most popular product is tri(2-ethylhexyl)trimellitate.
Trimellitic anhydride is also used to synthesize polyester resins.
TMA can also be applied to curing agent of epoxy resins.

3. Packaging and storage
TMA is packaged in plastic woven bags lined with polyethylene bags, with a net weight of 25kg per bag, which can also be determined according to user needs.
Store in a cool and ventilated place indoors, avoid moisture and exposure, and the storage period is twelve months.
4. Safety protection
Moderately toxic by ingestion. Has caused pulmonary edema from inhalation. Irritant to lungs and air passages. May be a powerful allergen. Typical attack consists of breathlessness, wheezing, cough, running nose, immunologcal sensitization, and asthma symptoms. When heated to decomposition it emits acrid smoke and irritating fumes.
