inkcazelo emfutshane:

i-p-Phenylenediamine (isiNgesi i-p-Phenylenediamine), ekwaziwa ngokuba yi-Ursi D, yenye yeedamines ezinuka kamnandi. Imveliso ecocekileyo imhlophe ukuya kwi-lavender crystals, ejika ibe mfusa okanye ibe mdaka omnyama xa ibonakaliswe emoyeni.
umbala. Inyibilika kancinci kumanzi abandayo, inyibilika kwi-ethanol, ether, chloroform kunye nebenzene.
Ingasetyenziselwa ukulungisa idayi ze-azo, iipolymers zemolekyuli ephezulu, kwaye ingasetyenziselwa ukuvelisa idayi zoboya, i-raber antioxidants kunye nabaphuhlisi beefoto. Isetyenziselwa ikakhulu i-aramid, i-azo dyes, idayi yesulfure, idayi ye-asidi, kwaye ingasetyenziswa njengoboya abamnyama D. Ukuveliswa kwe-Mao Pi Black DB, i-Mao Pi Brown N2, kunye ne-Chemicalbook rubber antioxidants DNP, DOP, kunye ne-MB. Ikwasetyenziswa njengemathiriyeli ekrwada yedayi yeenwele zokuthambisa i-Ursi D uthotho, inhibitor ye-polymerization yepetroli kunye nomphuhlisi. Njengedayi yeekhemikhali, i-p-phenylenediamine okwangoku ivunyelwe ukuba isetyenziswe ekuveliseni idayi yeenwele, kodwa kukho izithintelo ezicacileyo kubungakanani bokusetyenziswa.
Ifunyenwe ngokunciphisa i-p-nitroaniline nge-iron powder kwi-acidic medium. Beka i-iron powder kwi-hydrochloric acid, yitshise kwi-90 ° C, kwaye ungeze i-p-nitroaniline ngelixa uvuselela. Emva kokuba ukongeza kugqityiwe, sabela kwi-95-100 ° C nge-0.5h, kwaye emva koko wongeze i-hydrochloric acid egxininisiweyo kwi-dropwise ukugqiba ukuhla kwe-Chemicalbook reaction. Emva kokupholisa, nciphisa ngesisombululo esigcweleyo sesodium carbonate kwi-pH 7-8, ubilise kwaye uhluze ngelixa ushushu, kwaye uhlambe ikhekhe lokucoca ngamanzi ashushu. Hlanganisa i-filtrate kunye ne-washing liquid, gxininisa phantsi koxinzelelo oluncitshisiweyo, i-crystallize ngokupholisa okanye i-distill phantsi koxinzelelo oluncitshisiweyo lokufumana i-p-phenylenediamine kunye nesivuno se-95%.
