3-nitrotoluene; m-nitrotoluene

Cov ntaub ntawv tseem ceeb:

Brief kev taw qhia3-nitrotoluene yog tau los ntawm toluene nitrated nrog tov acid hauv qab 50 ℃, ces fractionated thiab refined. Nrog rau qhov sib txawv cov tshuaj tiv thaiv thiab catalysts, cov khoom sib txawv tuaj yeem tau txais, xws li o-nitrotoluene, p-nitrotoluene, m-nitrotoluene, 2, 4-dinitrotoluene thiab 2, 4, 6-trinitrotoluene. Nitrotoluene thiab dinitrotoluene yog cov khoom nruab nrab tseem ceeb hauv tshuaj, dyes thiab tshuaj tua kab. Nyob rau hauv cov kev mob tshwm sim dav dav, muaj ntau cov khoom ortho tshaj cov para-sites nyob rau hauv peb intermediates ntawm nitrotoluene, thiab para-sites yog ntau tshaj para-sites. Tam sim no, kev ua lag luam hauv tsev muaj kev xav tau zoo rau cov neeg nyob ib sab thiab para-nitrotoluene, yog li cov chaw hauv cheeb tsam nitration ntawm toluene tau kawm ob qho tib si hauv tsev thiab txawv teb chaws, vam tias yuav nce cov txiaj ntsig ntawm cov nyob ib sab thiab para-toluene kom ntau li ntau tau. Txawm li cas los xij, tsis muaj qhov tshwm sim zoo tshaj plaws tam sim no, thiab kev tsim ntawm ib qho nyiaj ntawm m-nitrotoluene yog kev zam. Vim tias kev txhim kho thiab kev siv ntawm p-nitrotoluene tsis tau khaws cia rau lub sijhawm, cov khoom siv los ntawm nitrotoluene nitration tsuas yog muag tau ntawm tus nqi qis lossis ntau cov khoom muag yog overstocked, ua rau muaj kev siv tshuaj lom neeg zoo.
