Ndi mankhwala opangira mankhwala, omwe amagwiritsidwa ntchito makamaka ngati mankhwala ophera tizilombo, utoto, mankhwala, pulasitiki ndi zida zopangira fiber.Monga herbicide chloromyron, etc., amatha kupanga p-toluidine, p-nitrobenzoic acid, p-nitrotoluene sulfonic acid, 2-chloro-4-nitrotoluene, 2-nitro-4-methylaniline, dinitrotoluene ndi zina zotero.
Njira yokonzekera ndikuwonjezera toluene ku riyakitala ya nitrification, kuziziritsa mpaka 25 ℃, kuwonjezera asidi osakanikirana (asidi ya nitric 25% ~ 30%, sulfuric acid 55% ~ 58% ndi madzi 20% ~ 21%), kutentha. limatuluka, sinthani kutentha kuti musapitirire 50 ℃, pitirizani kusonkhezera kwa maola 1 ~ 2 kuti muthe kuyankha, kuyimirira 6h, kulekana kwa nitrobenzene, kutsuka, kutsuka kwa alkali, ndi zina zotero.Chemicalbook crude nitrotoluene ili ndi o-nitrotoluene, p-nitrotoluene ndi m-nitrotoluene.Nitrotoluene yaiwisi imasungunuka mu vacuum, o-nitrotoluene yambiri imalekanitsidwa, gawo lotsalira lomwe lili ndi p-nitrotoluene yambiri limalekanitsidwa ndi vacuum distillation, ndipo p-nitrotoluene imapezeka mwa kuzizira ndi crystallization, ndipo meta-nitrobenzene imapezeka. mwa distillation pambuyo kudzikundikira mu mowa mayi pa kulekana ndi para.
ng'oma kanasonkhezereka 200kg/ng'oma;Kulongedza malinga ndi zomwe kasitomala akufuna.Kuzizira ndi mpweya wokwanira, kutali ndi moto, gwero la kutentha, kuteteza kuwala kwa dzuwa, kupewa kuwala.
