Pyromellitic Dianhydride CAS NO. 89-32-7

Pyromellitic Dianhydride CAS NO. 89-32-7

Information of Pyromellitic Dianhydride CAS NO. 89-32-7 Pyromellitic dianhydride CAS NO. 89-32-7 is an organic compound with the formula C6H2(C2O3)2. It is the double carboxylic acid anhydride that is used in the preparation of polyimide polymers such as Kapton. Pyromellitic dianhydride CAS NO. 89-32-7 is a White to pale yellow powder. Pyromellitic dianhydride CAS NO. 89-32-7 is prepared by gas-phase oxidation of 1,2,4,5-tetramethylbenzene (or related tetrasubstituted benzene derivatives). An idealized equation is: C6H2(CH3)4 + 6 O2 → C6H2(C2O3)2 + 6 H2O.
