Yimathiriyeli ekrwada ebalulekileyo yeekhemikhali, ikakhulu esetyenziswa njengendawo ephakathi yesibulali-zinambuzane, idayi, iyeza, iplastiki kunye nezixhobo zefayibha zokwenziwa. Okufana ne-herbicide chloromyron, njl., Inokwenza kwakhona i-p-toluidine, i-p-nitrobenzoic acid, i-p-nitrotoluene sulfonic acid, i-2-chloro-4-nitrotoluene, i-2-nitro-4-methylaniline, i-dinitrotoluene njalo njalo.
Indlela yokulungiselela kukongeza i-toluene kwi-reactor ye-nitrification, uyipholise ibe ngaphantsi kwe-25 ℃, yongeza i-asidi edibeneyo (i-nitric acid 25% ~ 30%, i-sulfuric acid 55% ~ 58% kunye namanzi angama-20% ~ 21%), ubushushu buphakama, lungisa ubushushu ukuba ungadluli kwi-50 ℃, qhubeka uvuselela i-200 ℃, qhubeka uqhubela phambili ukuvelisa i-6 ℃, qhubeka uqhubela phambili ukuvelisa i-6. Ukwahlula i-nitrobenzene, ukuhlamba, ukuhlanjwa kwealkali, njalo njalo. I-Chemicalbook crude nitrotoluene iqulethe i-o-nitrotoluene, i-p-nitrotoluene kunye ne-m-nitrotoluene. I-nitrotoluene ekrwada i-distilled kwi-vacuum, ininzi ye-o-nitrotoluene iyahlukana, i-fraction eseleyo equlethe i-p-nitrotoluene eninzi ihlulwe yi-vacuum distillation, kunye ne-p-nitrotoluene ifunyenwe ngokupholisa kunye ne-crystallization, kwaye i-meta-nitrotoluene ifumaneka ngokuxutywa kwe-distillation ngexesha le-motherpacuculation emva kwe-ac liquity.
igubu elenziwe igalvanized 200kg/drum; Ukupakisha ngokweemfuno zomthengi. Ukupholisa kunye nokungenisa umoya, kude nomlilo, umthombo wokushisa, ukuthintela ukukhanya kwelanga, ukuphepha ukukhanya.
