- Kev Taw Qhia Vim muaj kev txwv ntawm lub zog roj av hauv tsev thiab thev naus laus zis refining, cov khoom roj uas tsim los ntawm cov chaw ua roj av ib txwm muaj nyob hauv kev ua lag luam tsis txaus, uas ua rau muaj ntau cov khoom roj sib xyaw ua rau muaj kev lag luam ntau. Cov roj av sib xyaw ib txwm feem ntau yog sib xyaw nrog cov roj naphtha sib xyaw ua cov khoom siv raw. Txawm li cas los xij, nyob rau hauv keeb kwm yav dhau los ntawm cov nqi khoom siv raw siab thiab qhov siab tshaj plaws ntawm cov txiaj ntsig, cov tshuaj aniline feem ntau yog siv ua cov roj av ntxiv tsis zoo. Txhawm rau ua kom cov ntsuas zoo ntawm cov roj av nrog cov tshuaj ntxiv no ua tau raws li tus qauv roj av hauv tebchaws, piv txwv li, ntxiv 1% (feem pua ntawm pawg) N-methylaniline tuaj yeem ua rau tus lej octane nce ntxiv los ntawm 2-4 units [1]. Txawm li cas los xij, cov tshuaj ntxiv aniline muaj kev phom sij rau kev txav mus los thiab kev nyab xeeb ntawm cov tsheb, thiab N-methylanilines yog cov tshuaj uas muaj nitrogen, uas yuav ua rau muaj kev nce ntxiv ntawm cov ntsiab lus ntawm nitrogen oxides hauv cov pa tawm ntawm lub tsheb, ua rau muaj kev cuam tshuam tsis zoo rau ib puag ncig huab cua thiab tib neeg kev noj qab haus huv. Cov khoom tseem ceeb ntawm cov tshuaj ntxiv aniline suav nrog aniline, N-methylaniline, o-methylaniline, p-methylaniline, m-methylaniline thiab N, n-dimethylaniline. Tam sim no, cov txheej txheem feem ntau tshaj tawm rau kev tshawb pom cov tshuaj methylaniline suav nrog naphthalene diethylamine spectrophotometry, roj chromatography-nitrogen chemiluminescence nrhiav, kev ua haujlwm siab kua chromatography, thiab lwm yam [2-4]. Cov tshuaj naphthalene diethylamine spectrophotometry ib txwm cuam tshuam rau qhov kev txiav txim siab vim muaj qhov tshwm sim ntawm cov tshuaj tiv thaiv sab, thiab txoj kev HPLC yog qhov cuam tshuam los ntawm kev cuam tshuam ntawm roj av matrix.
Txoj kev ntsuas roj chromatograph-nitrogen chemiluminescence yuav tsum tau npaj lub tshuab ntsuas nitrogen chemiluminescence kim uas tuaj yeem xaiv tau nitrogen. Tus qauv hauv tebchaws uas nyuam qhuav sau tseg (tsis tau luam tawm) "Gas Chromatography rau Kev Txiav Txim Siab ntawm Oxycompounds thiab aniline Compounds hauv roj av" kuj piav qhia txog txoj kev ntsuas siv Deans hloov ntawm ob kab polarity sib txawv siv lub tshuab ntsuas hydrogen ion nplaim taws uas pheej yig thiab pheej yig. Rau txoj kev no, ThermoFisher Scientific tau luam tawm daim ntawv thov (Cov Lus Cim Daim Ntawv Thov C GC-50). Ua kom yooj yim, daim ntawv no qhia txog txoj kev ib kab sai dua raws li tus qauv hauv zos DB37 / T-2650 uas tau tshaj tawm los ntawm Shandong Province hauv xyoo 2015 [5]. Cov txiaj ntsig qhia tau tias txoj kev no yooj yim rau kev ua haujlwm, nrog kev rov ua dua zoo thiab qhov tseeb siab. Tib lub sijhawm, txoj kev tau ua kom zoo dua los daws qhov teeb meem ntawm kev cuam tshuam ntawm aniline quantification los ntawm roj av matrix composition.
2. Txheej txheem cej luam ntawm lub hauv paus ntsiab lus ntawm txoj kev Ntawm ib kem polar polyethylene glycol (PEG), cov tshuaj aniline hauv cov roj av hauv tsheb tau sib cais los ntawm cov roj av matrix, thiab acetophenone tau siv ua tus qauv sab hauv. Cov ntsiab lus ntawm aniline, N-methylaniline, o-methylaniline, p-methylaniline, m-toluidine thiab N, n-dimethylaniline hauv cov roj av hauv tsheb tau txiav txim siab los ntawm cov roj chromatograph uas muaj lub tshuab ntes nplaim taws (FID), thiab qhov concentration ntawm txhua yam khoom tau suav los ntawm kev siv rau tus qauv sab hauv.
4: Tsis ntev los no, qhov kev thov ua lag luam loj heev, peb tam sim no mus txhua yam los tsim khoom, kev siv thev naus laus zis yog txoj kev tsim khoom tas mus li, uas yog, roj chromatography
