Inombolo yeCas: 89-32-7 PMDA I-Pyromellitic dianhydride
Intshayelelo emfutshane
I-Pyromellitic dianhydride (PMDA), iimveliso ezisulungekileyo zimhlophe okanye ziikristale ezimthubi.Ukuvezwa kumoya ofumileyo kuya kukhawuleza ukufunxa ukufuma emoyeni kunye ne-hydrolyzed kwi-Pyromellitic Acid.Inyibilike kwi-dimethyl sulfoxide, i-dimethylformamide, i-acetone kunye nezinye izinyibilikisi ze-organic, ezinganyibilikiyo kwi-ether, i-chloroformand benzene.Isetyenziswa kakhulu njengemathiriyeli ekrwada ye-polyimide, kunye ne-arhente edibanisayo ukwenza i-epoxy ephilisa i-ejenti kunye nokuphela kwe-polyester resin.
I-Pyromellitic acid(PMA), ekwaziwa njenge-1,2,4,5-benzenetetracarboxylicacid, emhlophe ukuya kobutyheli bekristale engumgubo, isetyenziswa ikakhulu kwi-thesynthesis ye-polyimide, i-octyl pyromelliate, njl. njl., yeyona nto iphambili ekuvelisweni kwearhente yokunyanga .
