Tau txais txiaj ntsig los ntawm kev loj hlob sai ntawm kev lag luam hauv qab, kuv lub teb chaws tau dhau los ua tus tsim khoom loj tshaj plaws ntawm p-chlorotoluene hauv ntiaj teb.Ntxiv rau qhov ua tau raws li qhov xav tau ntawm kev ua lag luam hauv tsev, cov khoom lag luam tseem raug xa tawm mus rau txawv teb chaws kev lag luam.
p-Chlorotoluene, tseem hu ua 4-chlorotoluene, muaj cov mis mos molecular C7H7Cl.Cov tsos ntawm p-chlorotoluene yog tsis muaj xim thiab pob tshab kua, nrog tshwj xeeb tsw, toxicity thiab irritation.p-Chlorotoluene yog insoluble nyob rau hauv dej, soluble nyob rau hauv cov organic solvents xws li cawv, ether, benzene, acetone, chloroform, thiab lwm yam. Nws yog flammable, flammable nyob rau hauv cov ntaub ntawv ntawm qhib nplaim taws, hnyav reacts nyob rau hauv cov ntaub ntawv ntawm oxidizing tus neeg saib xyuas, thiab tej zaum yuav tawg nyob rau hauv airtight. ntim.Para-chlorotoluene yog hom khoom tseem ceeb tshaj plaws ntawm peb isomers ntawm chlorotoluene.
Txoj kev npaj ntawm p-chlorotoluene feem ntau suav nrog toluene aromatic nplhaib chlorination txoj kev, p-toluidine diazotization txoj kev thiab hais txog.Ntawm lawv, toluene aromatic nplhaib chlorination txoj kev yog cov txheej txheem kev npaj tseem ceeb.Nws siv cov toluene qhuav ua raw khoom, ntxiv cov catalyst, qhia cov roj chlorine, ua cov tshuaj tiv thaiv chlorination nyob rau hauv qee qhov kub thiab txias kom tau txais cov khoom, thiab tom qab ntawd ua tiav cov txheej txheem sib cais kom tau txais p-chlorotoluene.Cov khoom ntawm txoj kev no yog sib xyaw ntawm p-chlorotoluene thiab o-chlorotoluene.Hauv cov txheej txheem ntau lawm, muaj qhov sib txawv ntawm qhov tso zis piv ntawm ob qho tib si siv cov catalysts sib txawv.Txoj kev sib cais tuaj yeem yog txoj kev rectification crystallization, molecular sieve adsorption method, thiab lwm yam.
p-Chlorotoluene feem ntau yog siv rau hauv tshuaj, tshuaj tua kab, dyes, kuab tshuaj, organic synthesis thiab lwm yam teb.Hauv kev lag luam tshuaj, p-chlorotoluene tuaj yeem siv los tsim cov ntsiav tshuaj clomezadone, pyrimethamine, clotrimide, thiab lwm yam;nyob rau hauv lub tshav pob ntawm cov tshuaj tua kab, nws tuaj yeem siv los tsim cov tshuaj tua kab, tshuaj tua kab, tshuaj tua kab, thiab lwm yam. Nyob rau hauv cov tshuaj dyes, nws tuaj yeem siv los tsim cov kua qaub xiav 90, CI disperse xiav 109, thiab lwm yam.;nyob rau hauv lub teb ntawm organic synthesis, nws yuav siv tau los npaj p-chlorobenzaldehyde, p-chlorobenzoic acid, p-chlorobenzonitrile, p-chlorobenzoyl chloride thiab lwm yam .;kuj tseem siv tau ua roj hmab, resin hnyav.
Raws li "2021-2025 Tuam Tshoj p-chlorotoluene kev lag luam kev lag luam kev lag luam kev loj hlob thiab kev tsim khoom thiab muag cov ntaub ntawv txheeb xyuas" tso tawm los ntawm Xinsijie Industry Research Center, p-chlorotoluene tuaj yeem nkag mus rau ntau yam kev cuam tshuam los npaj ntau yam khoom siv tshuaj zoo, thiab nws cov derivatives. yog cov khoom xav tau tshaj plaws thiab siv dav tshaj plaws ntawm chlorotoluene isomers.Tau txais txiaj ntsig los ntawm kev loj hlob sai ntawm kev lag luam hauv qab, kuv lub teb chaws tau dhau los ua tus tsim khoom loj tshaj plaws ntawm p-chlorotoluene hauv ntiaj teb.Ntxiv rau qhov ua tau raws li qhov xav tau ntawm kev ua lag luam hauv tsev, cov khoom lag luam tseem raug xa tawm mus rau txawv teb chaws kev lag luam.Nws kwv yees tias txij xyoo 2020 txog 2025, lub ntiaj teb p-chlorotoluene kev ua lag luam yuav loj hlob ntawm kev loj hlob ntawm kwv yees li 4.0%, thiab kuv lub teb chaws p-chlorotoluene kev lag luam muaj kev vam meej zoo.
Feem ntau ntawm kuv lub teb chaws p-chlorotoluene cov tuam txhab tsim cov khoom lag luam qis.Yog li ntawd, hauv kuv lub teb chaws p-chlorotoluene ntau lawm, qhov kev faib ua feem ntawm kev siv tus kheej los ntawm kev lag luam yog siab, thiab kev faib ua feem ntawm kev muag khoom yog me me.
Raws li cov kws tshuaj ntsuam xyuas kev lag luam los ntawm Xinsijie, p-chlorotoluene yog ib qho tseem ceeb ntawm cov khoom siv tshuaj zoo thiab cov tshuaj zoo nruab nrab.Nws yog dav siv hauv tshuaj, tshuaj tua kab, dyes thiab lwm yam kev lag luam, thiab kev lag luam xav tau txuas ntxiv mus.
