Waa walxo kiimiko ah oo ceeriin ah oo muhiim ah, oo inta badan loo isticmaalo dhex dhexaad ka ah sunta cayayaanka, dheeha, daawada, balaastigga iyo caawiyayaasha fiber-synthetic.Sida chloromyron herbicide, iwm, waxay sidoo kale soo saari kartaa p-toluidine, p-nitrobenzoic acid, p-nitrotoluene sulfonic acid, 2-chloro-4-nitrotoluene, 2-nitro-4-methylaniline, dinitrotoluene iyo wixii la mid ah.
Habka diyaarinta waa in lagu daro toluene in reactor nitrification, qaboojiso in ka hooseeya 25 ℃, ku dar acid isku qasan (nitric acid 25% ~ 30%, sulfuric acid 55% ~ 58% iyo biyaha 20% ~ 21%), heerkulka kor u kaca, hagaajin heerkulka si aan ka badnayn 50 ℃, sii walaaq 1 ~ 2 saacadood si loo dhammeeyo falcelinta, u istaag 6h, kala soocidda nitrobenzene ah, dhaqidda, alkali dhaqidda, iyo wixii la mid ah.Kiimikada nitrotoluene cayriin waxa ku jira o-nitrotoluene, p-nitrotoluene iyo m-nitrotoluene.Nitrotoluene-ka cayriin waxaa lagu nadiifiyaa vacuum, inta badan o-nitrotoluene waa la kala soocaa, jajabka haraaga ah ee ka kooban p-nitrotoluene oo dheeraad ah ayaa lagu kala saaraa nadiifinta vacuum, p-nitrotoluene waxaa lagu helaa qaboojin iyo crystallization, iyo meta-nitrobenzene ayaa la helay. by distillation ka dib raasamaal ee khamriga hooyada inta lagu guda jiro kala soocidda para.
durbaan galvanized 200kg / durbaan;Baakad si waafaqsan shuruudaha macmiilka.Qabow oo hawo leh, ka fog dabka, isha kulaylka, ka ilaali qorraxda tooska ah, iska ilaali iftiinka.
