Product Specification:

Product Description:
p - phenylenebis(trimellitate anhydride) usually appears as a white to off - white crystalline solid. Structurally, it consists of a central benzene ring with two trimellitate anhydride moieties attached at the para - positions. Each trimellitate anhydride group contains an anhydride ring, which imparts reactivity to the molecule.

It has low solubility in water but dissolves in polar organic solvents such as N,N - dimethylformamide (DMF) and dimethyl sulfoxide (DMSO). The anhydride groups are sensitive to moisture and can hydrolyze to form carboxylic acids.

Under normal storage, it's stable when dry, but high temperatures or strong acids/bases can lead to decomposition. In organic synthesis, it's an important building block for producing high - performance polymers. It can enhance the thermal stability and mechanical properties of polymers. Store it in a cool, dry place, away from light, moisture, and strong chemicals.

Application: 

p - phenylenebis(trimellitate anhydride) is mainly used in organic synthesis as a key building block for high - performance polymers. It significantly boosts polymers' thermal stability, making them suitable for high - temperature applications. Also, it enhances mechanical properties, like strength and toughness, which is beneficial for manufacturing durable materials in aerospace, electronics, and automotive industries.
