M-nitrotoluene yog cov kua daj los yog siv lead ua. Nws kuj tseem yuav zoo li cov kua daj daj uas muaj ntxhiab tsw ntawm nitrobenzene. Kev siv m-nitrotoluene yog dav heev. Nws feem ntau yog siv los npaj m-toluidine thiab cov xim zas. Nws kuj tseem siv rau hauv cov tshuaj tua kab, tshuaj, cov neeg tsim xim, yas thiab cov khoom siv fiber ntau. Tshwj xeeb:

Kev tsim cov m-toluidine: m-nitrotoluene siv tau ua cov khoom siv raw los tsim cov m-toluidine, uas yog cov khoom siv nruab nrab tseem ceeb rau ntau yam xim thiab cov khoom siv tshuaj.
Kev npaj xim: m-nitrotoluene muaj cov ntawv thov tseem ceeb hauv kev lag luam xim thiab tuaj yeem siv los npaj ntau yam xim.
Tshuaj tua kab thiab tshuaj intermediates: Nws kuj yog ib qho tseem ceeb hauv kev tsim cov tshuaj tua kab thiab qee yam khoom siv tshuaj.
Lwm cov ntawv thov: m-nitrotoluene kuj tseem siv rau hauv kev tsim cov khoom xws li cov neeg tsim xim, plastics thiab cov khoom siv fiber ntau.

Hauv kev xaus lus, m-nitrotoluene yog cov organic compound ntau yam uas muaj ntau yam kev siv hauv cov tshuaj, cov xim, cov tshuaj tua kab, cov tshuaj thiab lwm yam teb.

Qhov xwm txheej ua lag luam tsis ntev los no ntawm m-nitrotoluene qhia tau hais tias nws tus nqi sib txawv ntawm ntau thaj chaw thiab hom, tab sis tseem ruaj khov tag nrho. Tshwj xeeb:

Nqe lag luam: Raws li cov ntaub ntawv tshiab kawg, tus nqi lag luam ntawm m-nitrotoluene (specification 99.5%) txawv ntawm qhov chaw mus rau qhov chaw. Piv txwv li, hauv xeev Shandong, tus nqi lag luam ntawm qee lub npe yog 11,000 yuan / ton, thaum nyob rau qee thaj chaw xws li Shanghai, cov neeg muag khoom muab tus nqi txij li 8,500 yuan / ton txog 11,500 yuan / ton. Tus nqi hauv xeev Hubei kuj ruaj khov ntawm kwv yees li 11,000 yuan / ton.
Hom thiab cov lus qhia: Muaj ntau hom thiab cov lus qhia ntawm m-nitrotoluene hauv kev ua lag luam, suav nrog tab sis tsis txwv rau Wencheng Chemical, Ronghe, thiab hauv tsev, thiab cov lus qhia feem ntau yog 99.5% purity. Muaj qhov sib txawv ntawm cov nqi khoom ntawm ntau hom thiab cov lus qhia, uas tej zaum yuav cuam tshuam nrog cov yam xws li cov khoom siv raw zoo, cov txheej txheem tsim khoom, thiab kev cuam tshuam ntawm hom.
Kev Lag Luam: Kev txiav txim los ntawm kev lag luam tsis ntev los no, tus nqi ntawm m-nitrotoluene tseem ruaj khov, tab sis tus nqi tshwj xeeb tseem cuam tshuam los ntawm ntau yam xws li kev muab khoom thiab kev thov hauv khw, tus nqi khoom siv raw, thiab ib puag ncig txoj cai. Yog li ntawd, tus nqi yuav hloov pauv yav tom ntej thiab cov neeg koom nrog kev lag luam raug qhia kom ua tib zoo mloog rau kev txhim kho kev lag luam.
