Kiriata ma. Ka huri i te rosy i te marama. Ka huri te papura ki te rangi. Ira whakarewa 140℃. Kohuatanga 267℃. Ka taea te sublimated. He iti te wairewa ki te wai matao, ka whakarewahia ki te waihano, ether, chloroform me te benzene. Ka tauhohe ki nga waikawa pararopi ki te hanga tote ngawari ki te wairewa. Ka whakamahia i roto i te hanga waikano azo me nga waikano whanariki, me etahi atu, ka whakamahia hei waikano huruhuru (Fur Black D, Ursol D, Fur Black D, Ursol D, Fur Black D ranei) me nga kaihoko whakawhanake. Ko tenei hua no te waahanga 3 nga mate pukupuku. Ka puta ma te whakaiti i te p-nitroaniline.

Ko te tikanga whakaputa

Ka whiwhihia ma te whakaiti i te p-nitroaniline me te paura rino i roto i te reo waikawa. Kuhua te paura rino ki roto i te waikawa pūhaumāota, whakamahana ki te 90°C, ka tāpirihia te p-nitroaniline i te wā e kōrorirori ana. Ka oti te taapiri, tauhohe i te 95-100°C mo te 0.5 haora, katahi ka taapirihia te waikawa maaota ki te topata kia oti te tauhohenga whakahekenga pukapuka matū. I muri i te whakamatao, whakanoatia ki te wairewa konutai waro waro ki te pH 7-8, kohuatia ka tātari i te wa e wera ana, ka horoi i te keke tātari ki te wai wera. Whakakotahitia te filtrate me te wai horoi, whakakorikori i raro i te pehanga iti, whakamaarama ma te whakamatao ma te whakamatao ranei i raro i te pehanga iti kia whiwhi p-phenylenediamine me te 95%.
