CAS NO. 89-32-7 Pyromellitic Dianhydride

CAS NO. 89-32-7 Pyromellitic Dianhydride

Information of CAS NO. 89-32-7 Pyromellitic Dianhydride CAS NO. 89-32-7 Pyromellitic Dianhydride 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. CAS NO. 89-32-7 Pyromellitic Dianhydride 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.
