Aniline yog siv rau hauv kev tsim cov xim pleev xim, tshuaj, cov resins, cov xim pleev xim, cov tshuaj tsw qab, cov roj hmab vulcanized thiab txawm tias cov kuab tshuaj. Cov tshuaj txaus ntshai thiab cov tshuaj lom neeg cuam tshuam rau lub neej thaum ntxov ntawm cov tsiaj hauv dej hiav txwv. Raws li US Environmental Protection Agency (EPA), Cov tshuaj lom neeg ib puag ncig thiab zaub mov, Cov dej haus uas muaj kuab lom Candidate Compound 3 (CCL3).
2. Aniline yog ib qho khoom siv tseem ceeb, kev tsim cov tshuaj tua kab tuaj yeem tau los ntawm aniline, alkyl aniline, N - alkyl aniline nyob ib sab nitro aniline, o-phenylendiamine, phenylhydrazine, cyclohexylamine thiab lwm yam, tuaj yeem siv ua fungicide tiv thaiv xeb sodium, noob ntsuj plig, amine methyl Chemicalbook sterilization, sterilization amine, carbendazim, nws tus ntsuj plig, benomyl, triazophos insecticide, pyridazine sulfur phosphorus, quetiapine phosphorus, Intermediates ntawm herbicides alachlor, acetochlor, butachlor, cycloazinone, imidazole quinolinic acid, thiab lwm yam.
3. Aniline yog ib qho tseem ceeb nruab nrab. Ntau tshaj 300 hom khoom tseem ceeb yog tsim los ntawm aniline. Muaj li ntawm 80 lub tuam txhab tsim aniline hauv ntiaj teb, tag nrho cov peev xwm tsim khoom txhua xyoo tau tshaj 2.7 lab t / a, qhov tso zis ntawm kwv yees li 2.3 lab t; Qhov chaw siv tseem ceeb yog MDI, uas suav txog 84% ntawm tag nrho cov kev siv aniline hauv xyoo 2000. Hauv peb lub tebchaws, aniline feem ntau yog siv hauv MDI, kev lag luam zas xim, roj hmab ntxiv, tshuaj, tshuaj tua kab thiab cov organic intermediates. Kev siv aniline hauv xyoo 2000 yog 185,000 t, thiab qhov tsis txaus ntawm kev tsim khoom yuav tsum tau daws los ntawm kev xa khoom tuaj. Cov tshuaj aniline intermediates thiab cov khoom zas xim yog: 2, 6-diethyl aniline N-acetaniline, p-butyl aniline, o-phenylenediamine, diphenylenediamine, diazo-aminobenzene, 4,4'-diaminotriphenylmethane, 4,4' diaminodiphenylcyclohexyl methane,N, N-dimethylaniline, N-diethylaniline,N, n-diethylaniline, p-acetamide phenol, p-aminoacetophenone,4,4'-diethylaminophenone,4- (p-aminophenine) butyric acid, p-nitroaniline, N-nitrodianiline, β-acetaniline, 1, 4-diphenylaminourea, 2-phenylindole, p-benzaniline, N-formylaniline, n-benzoylaniline, n-acetaniline, 2,4,6-trichloraniline, p-chemicalbook iodoaniline, 1 - aniline - 3 - methyl - 5 - pyrazole ketones, hydroquinone, dicyclohexyl amine, 2 - (N - methyl aniline) acrylic nitrile, 3 - (N - diethyl aniline) acrylic nitrile, 2 - (N - diethyl aniline) ethanol, p-aminoazobenzene, phenylhydrazine, phenyl urea ib leeg, ob chav phenyl urea, ntawm sulfur cyano aniline, 4, 4 'diphenyl methane diisocyanate, phenyl methyl ntau zaus ntau dua Cyanate ester, 4-amino-acetanilide, N-methyl-N - (β-hydroxyethyl) aniline, n-methyl-N (β-chloroethyl) aniline,N, N-dimethyl-p-phenylenediamine,N,N,N',N' -tetramethyl-p-phenylenediamine,N, n-diethyl-p-phenylenediamine, 4,4' -methylenediamine (N, n-diethyl-p-phenylenediamine, phenylthiourea, diphenylenediamide, p-amino Benzene sulfonic acid, 4, 4 'diamino diphenyl methane benzoquinone, N, N - tiv thaiv ethanol puag aniline, acetyl acetanilide, aminophenol, N, N - methyl - ethyl benzyl aniline formyl aniline, N - methyl acetanilide, lub bromine acetanilide, ob npaug (rau amino cyclohexyl) methane, phenylhydrazone diphenyl kappa hydrazone thiab acetophenone phenylhydrazone - 2, 4 - disulfonic acid, aniline, p-aminoazobenzene - 4 'sulfonic acid, phenylhydrazine -4- sulfonic acid, thioacetanilide, 2-methylindole, 2, 3-dimethylindole, N-methyl-2-phenylindole.
4, siv ua ib qho tshuaj reagent analytical, kuj siv rau hauv kev tsim cov xim, cov resins, cov xim cuav thiab cov txuj lom.
5. Siv ua lub hauv paus tsis muaj zog, nws tuaj yeem ua rau cov ntsev hydrolyzed yooj yim ntawm cov ntsiab lus trivalent thiab tetravalent (Fe3 +, Al3 +, Cr3 +) nyob rau hauv daim ntawv ntawm hydroxide, yog li cais lawv ntawm cov ntsev ntawm cov ntsiab lus divalent (Mn2 +) uas nyuaj rau hydrolyze. Hauv kev tshuaj xyuas picrystal, los tshuaj xyuas cov ntsiab lus (Cu, Mg, Ni, Co, Zn, Cd, Mo, W, V) uas muaj peev xwm tsim cov tshuaj thiocyanate complex anions lossis lwm yam anions uas tuaj yeem ua rau aniline precipitated. Sim rau halogen, chromate, vanadate, nitrite, thiab carboxylic acid. Cov kuab tshuaj. Organic synthesis, zas xim.
