p-Faynileen diamine; 1,4-diaminobenzene

Crystal cad. Waxay isu beddeshaa casaan iftiinka. Waxay isu beddeshaa guduud hawada. Barta dhalaalka 140℃. Barta karkaraya 267℃. Waa la sublimated karaa. Si yar ayay ugu milmi kartaa biyaha qabow, waxaa ku milmi kara ethanol, ether, chloroform iyo benzene. Waxay la falgashaa asiidhyada aan organic ahayn si ay u sameeyaan cusbo si fudud ugu milmi kara biyaha. Waxaa loo isticmaalaa soo saarista rinjiyada azo iyo rinjiyada sulfur, iwm., waxaana loo isticmaalaa rinjiyada dhogorta (Duur Madow D, Ursol D ama Fur Madow D, Ursol D ama Fur Madow D) iyo wakiilada soo koraya. Badeecadani waxay ka tirsan tahay noocyada kansarka ee Qaybta 3aad. Waxaa lagu soo saaraa yareynta p-nitroaniline.

Habka wax soo saarka

Waxaa lagu helaa iyadoo la yareeyo p-nitroaniline iyadoo la isticmaalayo budada birta oo lagu shubay meel dhexdhexaad ah oo aashito leh. Budada birta ku rid aashitada hydrochloric, ku kululee ilaa 90°C, oo ku dar p-nitroaniline inta aad walaaqayso. Ka dib marka lagu daro la dhammeeyo, ka falceli 95-100°C muddo 0.5 saacadood ah, ka dibna ku dar aashitada hydrochloric ee xooggan si aad u dhammaystirto falcelinta dhimista kiimikada. Ka dib qaboojinta, dhexdhexaad ka dhig xalka sodium carbonate ee buuxa pH 7-8, karkari oo shaandhee inta uu kulul yahay, oo keega shaandhada ku dhaq biyo kulul. Isku dar dareeraha shaandhada iyo dhaqidda, xoogga saar cadaadiska la dhimay, ku shub qaboojin ama ku shub cadaadis la dhimay si aad u hesho p-phenylenediamine oo leh wax soo saar 95%.
