ividiyo yemveliso
Ukusetyenziswa kweMveliso
i-p-Phenylenediamine (isiNgesi i-p-Phenylenediamine), ekwaziwa ngokuba yi-Ursi D, yenye yeedamines ezinuka kamnandi. Imveliso esulungekileyo imhlophe ukuya kwikristale yelavender, ejika ibemfusa okanye ibemdaka omnyama xa ityhilekile emoyeni. Inyibilika kancinci kumanzi abandayo, inyibilika kwi-ethanol, ether, chloroform kunye nebenzene.
Ingasetyenziselwa ukulungisa idayi ze-azo, iipolymers zemolekyuli ephezulu, kwaye ingasetyenziselwa ukuvelisa idayi yoboya, i-antioxidants yerabha kunye nabaphuhlisi beefoto. Isetyenziselwa ikakhulu i-aramid, i-azo dyes, idayi yesulfure, idayi ye-asidi, kwaye ingasetyenziswa njengoboya obumnyama D. Ukuveliswa koboya obumnyama obuluhlaza be-DB, uboya obumdaka be-N2, kunye ne-raber antioxidants DNP, DOP kunye ne-MB.
Ikwasetyenziswa njengemathiriyeli ekrwada yedayi yeenwele zokuthambisa i-Ursi D uthotho, inhibitor ye-polymerization yepetroli kunye nomphuhlisi.
