What is Trimellitic Anhydride CAS 552-30-7？
Trimellitic Anhydride white powder or flakes. Melting point 168 ℃. Soluble in water and general organic solvents such as ethanol and acetone. Benzene tricarboxylic acid can be obtained by liquid-phase nitric acid oxidation and air oxidation using cobalt or manganese catalysts from the carbon nine fraction of aromatic hydrocarbons such as coal tar fractions, cracked gasoline, and catalytic reforming gasoline (mainly composed of 1,2,4-trimethylbenzene), followed by dehydration.
