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