O le Aniline o se mea mata taua, o le gaosiga o vailaʻau faʻasaina e mafai ona maua mai i le aniline, alkyl aniline, N - alkyl aniline e lata ane i le nitro aniline, o-phenylendiamine, phenylhydrazine, cyclohexylamine ma isi, e mafai ona faʻaaogaina o se fungicide e faasaga i le ele sodium, le fatu o le agaga, amine methyl Chemicalbook sterilization, sterilization amine, carbendazim, lona agaga, benomyl, triazophos insecticide, pyridazine sulfur phosphorus, quetiapine phosphorus, Intermediates o herbicides alachlor, acetochlor, butachlor, cycloazinone, imidazole quinolinic acid, ma isi.
3. O le Aniline o se vailaʻau taua. E silia ma le 300 ituaiga oloa taua e gaosia mai le aniline. E tusa ma le 80 kamupani gaosi aniline i le lalolagi, o le aofaʻi atoa o le gaosiga faaletausaga ua sili atu i le 2.7 miliona t/a, o le gaosiga e tusa ma le 2.3 miliona t; O le vaega autu e faʻaaogaina o le MDI, lea e aofia ai le 84% o le aofaʻi atoa o le faʻaaogaina o le aniline i le 2000. I lo tatou atunuu, o le aniline e masani ona faʻaaogaina i le MDI, alamanuia vali, mea faʻaopoopo paʻu, vailaʻau, vailaʻau faʻasaina manu faʻamaʻi ma vailaʻau faʻasaina faʻalenatura. O le faʻaaogaina o le aniline i le 2000 e 185,000 t, ma o le le lava o le gaosiga e manaʻomia ona foia e ala i le faʻaulufale mai. O vaila'au fa'alava ma vali o le aniline e aofia ai: 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-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 ta'itasi, phenyl urea fa'alua, o le sulfur cyano aniline, 4, 4 'diphenyl methane diisocyanate, phenyl methyl e tele taimi e sili atu 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',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 - faasaga i le ethanol base aniline, acetyl acetanilide, aminophenol, N, N - methyl - ethyl benzyl aniline formyl aniline, N - methyl acetanilide, le bromine acetanilide, faalua (i le amino cyclohexyl) methane, phenylhydrazone diphenyl kappa hydrazone ma le 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, faʻaaogaina o se vailaʻau faʻataʻitaʻi, faʻaaogaina foʻi i le tuʻufaʻatasiga o vali, resins, vali sese ma mea manogi.
5. A fa'aaogaina o se fa'avae vaivai, e mafai ona fa'aputuina ni masima faigofie ona fa'a-hydrolyze o elemene trivalent ma tetravalent (Fe3+, Al3+, Cr3+) i le tulaga o le hydroxide, ina ia vavae'eseina mai masima o elemene divalent (Mn2+) e faigata ona fa'a-hydrolyze. I le au'ili'iliga picrystal, e su'esu'e ai elemene (Cu, Mg, Ni, Co, Zn, Cd, Mo, W, V) e mafai ona fausia ai ni anion thiocyanate complex po'o isi anion e mafai ona fa'aputuina e le aniline. Su'ega mo halogen, chromate, vanadate, nitrite, ma le carboxylic acid. Mea e fa'a'avai ai vai. Fa'asologa fa'alenatura, gaosiga o vali.
