Ke lisebelisoa tsa bohlokoa tsa lik'hemik'hale tse tala, tse sebelisoang haholo e le setsi sa meriana e bolaeang likokoanyana, dae, meriana, polasetiki le li-synthetic fiber. Tse kang herbicide chloromyron, joalo-joalo, e ka boela ea etsa p-toluidine, p-nitrobenzoic acid, p-nitrotoluene sulfonic acid, 2-chloro-4-nitrotoluene, 2-nitro-4-methylaniline, dinitrotoluene joalo-joalo.
Mokhoa oa ho lokisa ke ho eketsa toluene ho nitrification reactor, e pholisoe ka tlase ho 25 ℃, eketsa asiti e tsoakiloeng (asiti ea nitric 25% ~ 30%, sulfuric acid 55% ~ 58% le metsi 20% ~ 21%), mocheso. e phahama, fetola mocheso hore o se ke oa feta 50 ℃, tsoela pele ho hlohlelletsa lihora tse 1 ~ 2 ho felisa karabelo, ema bakeng sa 6h, karohano ea nitrobenzene, ho hlatsoa, ho hlatsoa alkali, joalo-joalo. Chemicalbook crude nitrotoluene e na le o-nitrotoluene, p-nitrotoluene le m-nitrotoluene. Nitrotoluene e tala e tšeloa ka har'a vacuum, boholo ba o-nitrotoluene e arohane, karoloana e setseng e nang le p-nitrotoluene e ngata e arohanngoa ke vacuum distillation, 'me p-nitrotoluene e fumanoa ka ho pholisa le ho kristale,' me meta-nitrobenzene e fumanoa. ka distillation ka mor'a ho bokella joala bo mme nakong ea karohano ea para.
moropa o betliloeng oa 200kg/moropa; Ho paka ho latela litlhoko tsa moreki. Pholile le ventilated, hole le mollo, mocheso mohloli, thibela letsatsi le tobileng, qoba leseli.
