He rauemi matū nui, ka whakamahia te nuinga hei takawaenga mo te pesticide, te waikano, te rongoa, te kirihou me nga awhina muka waihanga. Pērā i te herbicide chloromyron, me ētahi atu, ka taea hoki te hanga p-toluidine, p-nitrobenzoic acid, p-nitrotoluene sulfonic acid, 2-chloro-4-nitrotoluene, 2-nitro-4-methylaniline, dinitrotoluene me etahi atu.
Ko te tikanga whakarite ko te taapiri i te toluene ki te reactor nitrification, whakamatao ki raro i te 25 ℃, taapirihia te waikawa whakauru (waikawa nitric 25% ~ 30%, waikawa pungatara 55% ~ 58% me te wai 20% ~ 21%), te pāmahana. ka piki ake, whakatikahia te pāmahana kia kaua e neke ake i te 50 ℃, haere tonu ki te whakaoho mo te 1 ~ 2 haora ki te whakamutu i te tauhohenga, tu mo te 6h, te wehenga nitrobenzene i hangaia, te horoi, te horoi alkali, me etahi atu. Kei roto i te pukapuka matū nitrotoluene crude o-nitrotoluene, p-nitrotoluene me te m-nitrotoluene. Ko te nitrotoluene makuku ka makuku i roto i te korehau, ka wehea te nuinga o te o-nitrotoluene, ko te hautanga toenga kei roto i te p-nitrotoluene ka wehea e te whakamaarama korehau, ka whiwhihia te p-nitrotoluene ma te whakamatao me te tioata, ka whiwhi te meta-nitrobenzene. na roto i te whakamarumaru i muri i te whakaemitanga i roto i te waipiro whaea i te wehenga o te para.
pahu piauau 200kg/drum; Kiki kia rite ki nga whakaritenga a te kaihoko. Matao me te hau, matara atu i te ahi, te puna wera, aukati i te ra tika, karo i te marama.
