Inombolo yeCas:89-32-7 PMDA Pyromellitic dianhydride
Isingeniso esifushane
I-Pyromellitic dianhydride (PMDA), imikhiqizo ehlanzekile ingamakristalu amhlophe noma aphuzi kancane.Ichayeke emoyeni oswakeme izomunca ngokushesha umswakama ovela emoyeni bese i-hydrolyzed ibe yi-Pyromellitic Acid.Incibilikiswe ku-dimethyl sulfoxide, i-dimethylformamide, i-acetone nezinye izincibilikisi eziphilayo, ezingancibiliki ku-ether, i-chloroform kanye ne-benzene.Isetshenziswa kakhulu njengempahla eluhlaza ye-polyimide, kanye ne-ejenti exhumanisayo ekwenzeni i-epoxy elaphayo kanye nokushabalala kwe-polyester resin.
I-Pyromellitic acid(PMA), eyaziwa nangokuthi i-1,2,4,5-benzenetetracarboxylicacid, ikristalu eyimpuphu emhlophe ukuya kokuphuzi, isetshenziswa kakhulu ekuhlanganiseni i-polyimide, i-octyl pyromelliate, njll., iyi-rawmaterial eyinhloko ekukhiqizeni i-ejenti yokwelapha yokuhlangana. .
