Cas nambala: 89-32-7 PMDA Pyromellitic dianhydride
Pyromellitic dianhydride (PMDA), zopangira zoyera ndi makhiristo oyera kapena achikasu pang'ono. Kuwonekera kwa mpweya wonyowa mwamsanga kumatenga chinyezi kuchokera mumlengalenga ndi hydrolyzed mu Pyromellitic Acid. Kusungunuka mu dimethyl sulfoxide, dimethylformamide, acetone ndi zina organic solvents, insoluble mu ether, chloroformand benzene. Amagwiritsidwa ntchito makamaka ngati zopangira za polyimide, ndi crosslinking agent popanga epoxy machiritso ndi kutha kwa utomoni wa polyester.
