Kev soj ntsuam online sai sai muab cov txiaj ntsig hloov pauv, ua kom luv luv ntawm kev tshawb fawb thiab kev loj hlob lub voj voog los ntawm 10 npaug piv rau kev soj ntsuam offline.
4-Nitro-o-xylene thiab 3-nitro-o-xylene yog ib qho tseem ceeb organic synthesis intermediates thiab yog ib qho tseem ceeb raw cov ntaub ntawv rau zus tau tej cov tshiab environmentally friendly tshuaj tua kab nrog high efficiency, tsawg toxicity thiab tsawg residue.Hauv kev lag luam, feem ntau ntawm lawv yog synthesized los ntawm nitrating o-xylene nrog nitrate-sulfur tov acid.Cov ntsuas tseem ceeb hauv cov txheej txheem o-xylene nitration suav nrog cov ntsiab lus ntawm o-xylene raw cov ntaub ntawv thiab cov isomer piv ntawm cov khoom nitration, thiab lwm yam.
Tam sim no, txoj kev soj ntsuam kev soj ntsuam rau cov ntsuas tseem ceeb no feem ntau yog cov kua chromatography, uas yuav tsum muaj cov txheej txheem tedious ntawm sampling, cov qauv ua ntej kev kho mob thiab cov kws tshaj lij tsom xam, thiab tag nrho cov txheej txheem yuav siv sij hawm ntau tshaj 30 feeb.Thaum lub sijhawm txhim kho cov txheej txheem txuas ntxiv mus rau qhov kev tawm tsam no, cov tshuaj tiv thaiv nws tus kheej tuaj yeem ua tiav nyob rau hauv li 3 feeb, thiab lub sij hawm tus nqi ntawm offline tsom xam yog siab.Yog tias muaj coob tus txheej txheem parameter tej yam kev mob yuav tsum tau soj ntsuam nyob rau hauv ib tug luv luv lub sij hawm ntawm lub sij hawm, cov kws tshawb fawb xav tau ib tug tiag tiag-lub sij hawm thiab raug online nrhiav kom tau txoj kev sai sai muab cov ntsiab lus cov ntaub ntawv thiab qhia cov kev taw qhia ntawm cov txheej txheem optimization.
Online spectroscopy thev naus laus zis tuaj yeem muab cov ntaub ntawv spectral ntawm o-xylene, 3-nitro-o-xylene, thiab 4-nitro-o-xylene hauv cov tshuaj tiv thaiv.Lub ncov thaj chaw ntawm cov yam ntxwv ncov cim los ntawm cov xub hauv daim duab saum toj no qhia txog cov ntsiab lus txheeb ze ntawm peb yam khoom raws.Nyob rau hauv daim duab hauv qab no, lub software ntse soj ntsuam cov khoom siv raw thiab cov khoom sib piv hauv qab 12 txheej txheem sib txawv.Nws yog qhov pom tseeb tias cov khoom siv raw hloov pauv raws li qhov xwm txheej 2 yog qhov siab tshaj plaws, thiab cov khoom siv raw hauv qhov xwm txheej 8 yuav luag tsis muaj tshuaj tiv thaiv.Cov kws tshawb fawb tuaj yeem txiav txim siab sai sai ntawm cov txheej txheem tsis zoo raws li cov ntsiab lus ntawm peb cov tshuaj hauv cov tshuaj tiv thaiv, tshuaj ntsuam xyuas qhov tsis zoo, thiab nce kev tshawb fawb thiab kev loj hlob ntawm ntau dua 10 zaug.
