Ka whiwhi i te chlorination me te oxidation o te p-nitrotoluene. Kuhua te p-nitrotoluene ki roto i te reactor maroke, i muri i te whakamahana me te rewa, whakauruhia he waea rino me nga tawerewere iodine, i te 58-62 , tukuna he hau maota equimolar, horoi ki te wai wera, whakakorea ki te konutai warowaiha, ka riringi ki roto. wai tio , ka oho ki te wehe i nga tioata, ka tātarihia hei tango i te wai, ka whakamaroke ki te whakamarumaru kia whiwhi 2-chloro-4-nitrotoluene. Na ka tapirihia kia 25 nga wa o te 1-2% konutai wairewa wairewa ki roto i te 2-chloro-4-nitrotoluene, whakamahana ki te koropupupupu matū, i raro i te whakaoho kaha, me ata tapirihia te konutai permanganate, kia mau te pāmahana ki te 100±1â, I muri i te taapiri, haere tonu whakakorikorihia, whakamauhia mo te 30min, kia whakamatao, ka tango i te konupora hauhā. I whakatikahia te filtrate ki te pH 1-2 me te waikawa waikawa, ka horoia te wai ki te wai huka, ka tohua ka whakamaroke i te 80 ° C kia whiwhi ai i te hua. Ka taea hoki te whakahaere i te chlorination i te aroaro o te ferric chloride, me te haere tonu ki te chlorine i te 58-62°C. Ko te tapeke o te chlorination me te oxidation he 70%.
