Ka mor'a lilemo tse ka bang lekholo tsa tsoelo-pele, indasteri ea lik'hemik'hale ea Chaena e fetohile naha e hōlang ka potlako ho fetisisa lefatšeng, 'me potoloho ea indasteri e khutšoanyane haholo ho feta ea indasteri ea lik'hemik'hale ea Europe, Amerika, Japane le Korea Boroa. Europe, Amerika le linaheng tse ling, ho nka lilemo tse seng kae feela ho fihla boemong bo phahameng, 'me indasteri ea lik'hemik'hale ea Chaena e haufi le ho fela. Phapang ke hore ka mor'a sethaleng se seholo sa indasteri ea lik'hemik'hale Europe le Amerika, palo ea lihlahisoa tse ntle tsa lik'hemik'hale tse tšehetsoeng ke thekenoloji e phahameng e eketseha haholo, ha Chaena, ka lebaka la tsoelo-pele e fokolang ea thekenoloji, 'maraka oa phepelo ea thepa e ntle. lik'hemik'hale li eketseha butle.

Lilemong tse 5-10 tse tlang, ts'ebetso e kholo ea indasteri ea lik'hemik'hale ea Chaena e tla fela mme ts'ebetso e ntle ea nts'etsopele e tla potlakisa. Hona joale, litsi tse ngata tsa lipatlisiso tsa malapeng, haholo-holo tse amanang le likhoebo tse etellang pele, li eketsa matsete a tsona ho etsa lipatlisiso le nts'etsopele ea lik'hemik'hale tse ntle.

Bakeng sa tataiso ea nts'etsopele ea lik'hemik'hale tse ntle Chaena, ea pele ke lipatlisiso tse tebileng tsa ts'ebetso e sebelisang li-hydrocarbon tse tlase-khabone e le lisebelisoa tse tala, 'me karolo e tlase e tsepamisitsoe haholo-holo ho li-intermediate tsa meriana, li-intermediate tsa chefo e bolaeang likokoanyana le masimo a mang. Ea bobeli, bakeng sa ts'ebetso e tebileng le ts'ebeliso ea li-polycarbon hydrocarbons, ho theosa le metsi ka lisebelisoa tse phahameng tsa lik'hemik'hale tse ntle, li-additives le masimo a mang; Ea boraro, bakeng sa karohano le tlhoekiso ea lisebelisoa tse tala tsa carbon hydrocarbon le ts'ebetso e tebileng le ts'ebeliso, ho ea tlaase ho surfactant, plasticizer le masimo a mang.

Ha ho nahanoa ka tekanyo ea litšenyehelo, katoloso ea indasteri e ntle ea lik'hemik'hale ea thepa e tala ea khabone e tlase ke mokhoa o theko e tlaase oa tlhahiso le lipatlisiso. Hajoale, litsi tse ngata tsa lipatlisiso tsa mahlale Chaena li ntse li tsoela pele ho atolosa lipatlisiso tsa indasteri e ntle ea lik'hemik'hale ea carbon hydrocarbon. Lihlahisoa tse emetseng ke katoloso e ntle ea lik'hemik'hale tsa ketane ea indasteri ea isobutylene le katoloso e ntle ea lik'hemik'hale tsa ketane ea indasteri ea aniline.

Ho latela lipatlisiso tsa pele, ketane ea indasteri ea lik'hemik'hale tse ntle tse fetang 50 e ekelitsoe ho theosa le bohloeki bo phahameng ba isobutene, 'me sekhahla sa ntlafatso sa indasteri ea lihlahisoa tse tlase se phahame. Aniline e na le mefuta e fetang 60 ea lik'hemik'hale tse ntle tse katoloso ea indasteri, litaelo tsa ts'ebeliso e tlase li ngata.

Hajoale, aniline e hlahisoa haholo ke catalytic hydrogenation ea nitrobenzene, e leng tlhahiso ea hydrogenation ea asiti ea nitric, hydrogen le benzene e hloekileng e le lisebelisoa tse tala. E sebelisoa ka tlaase ho metsi masimong a MDI, li-additives tsa rabara, lidae le li-intermediate tsa bongaka, li-additives tsa peterole joalo-joalo. benzene e hloekileng likhoebong tse hloekisang oli le lik'hemik'hale tse hlahisang lik'hemik'hale li ke ke tsa kopanngoa le lihlahisoa tsa oli, tse khothalletsang katoloso le ts'ebeliso ea ketane e tlase ea liindasteri ea benzene e hloekileng, e fetohileng sepheo sa indasteri ea lipatlisiso le nts'etsopele ea lik'hemik'hale.

Ho latela liindasteri tse fapaneng tseo lihlahisoa tsa p-aniline li sebelisoang ho tsona, li ka aroloa ka liindasteri tse latelang: Taba ea pele, ts'ebeliso lefapheng la rabara accelerator le antioxidant, e ka aroloang ka mefuta e mehlano ea lihlahisoa. , e leng p-aminobenzidine, hydroquinone, diphenylamine, cyclohexylamine le dicyclohexylamine. Boholo ba lihlahisoa tsena tsa aniline li sebelisoa tšimong ea antioxidant ea rabara, joalo ka p-amino diphenylamine e ka hlahisa antioxidant 4050, 688, 8PPD, 3100D, joalo-joalo.

Tšebeliso tšimong ea accelerator ea rabara le antioxidant ke tataiso ea bohlokoa ea tšebeliso ea aniline ho ea tlaase tšimong ea rabara, e ikarabellang ho feta 11% ea kakaretso ea tšebeliso ea aniline ho ea tlaase, lihlahisoa tse ka sehloohong ke p-aminobenzidine le hydroquinone.

Ka metsoako ea diazo, ho sebelisa aniline le nitrate le lihlahisoa tse ling, lihlahisoa tse ka hlahisoang ke p-amino-azobenzene hydrochloride, p-hydroxyaniline, p-hydroxyazobenzene, phenylhydrazine, fluorobenzene joalo-joalo. Lihlahisoa tsena li sebelisoa haholo masimong a dae, meriana le li-intermediates tsa chefo e bolaeang likokoanyana. Lihlahisoa tse emelang ke: p-amino-azobenzene hydrochloride, e leng dae ea maiketsetso ea azo, dae ea lentsoe la um, dae e qhalaneng, e sebelisoang hape ho etsa pente le pigment le sesupo, joalo-joalo P-hydroxyaniline e sebelisoa tlhahisong. ea sulphide blue FBG, acid e fokolang e khanyang ea 5G le lidae tse ling, ho etsoa ha paracetamol, antamine le lithethefatsi tse ling, tse sebelisoang hape ho hlahisa moqapi, antioxidant joalo-joalo.

Hajoale, metsoako e mengata ea aniline e sebelisoang indastering ea dae ea China ke p-amino-azobenzene hydrochloride le p-hydroxyaniline, e etsang karolo ea 1% ea tšebeliso e tlase ea noka ea aniline, e leng tataiso ea bohlokoa ea tšebeliso ea metsoako ea naetrojene ka tlase ho noka ea aniline. hape ke tataiso ea bohlokoa ea lipatlisiso tsa theknoloji ea indasteri ea hajoale.

Tšebeliso e 'ngoe ea bohlokoa e ka tlaase ho noka ea aniline ke halogenation ea aniline, e kang tlhahiso ea p-iodoaniline, o-chloroaniline, 2.4.6-trichloraniline, n-acetoacetaniline, n-formylaniline, phenylurea, diphenylurea, phenylthiourea le lihlahisoa tse ling. Ka lebaka la palo e kholo ea lihlahisoa tsa halogenation tsa aniline, ho hakanngoa esale pele hore ho na le mefuta e ka bang 20, e fetohileng tataiso ea bohlokoa ea katoloso ea ketane e ntle ea indasteri ea lik'hemik'hale ea aniline.

Boitšoaro bo bong ba bohlokoa ba aniline ke karabelo ea phokotso, joalo ka aniline le hydrogen ho hlahisa cyclohexamine, aniline le concentrated sulfuric acid le soda ho hlahisa bicyclohexane, aniline le sulfuric acid le sulfur trioxide ho hlahisa p-aminobenzene sulfonic acid. Boitšoaro ba mofuta ona bo hloka li-excipients tse ngata, 'me palo ea lihlahisoa tse tlase ha e kholo, hoo e ka bang mefuta e mehlano ea lihlahisoa.

 Har'a tsona, joalo ka p-aminobenzene sulfonic acid, ho etsa lidae tsa azo, tse sebelisoang e le setsi sa litšupiso, reagent ea liteko le tlhahlobo ea chromatographic reagent, le eona e ka sebelisoa e le chefo e bolaeang likokoanyana ho thibela mafome a koro. Dicyclohexamine, ke ho lokisetsa dae intermediates, hammoho le chefo e bolaeang likokoanyana textile koro mafome, hammoho le ho lokisetsa linoko le joalo-joalo.

Maemo a phokotso ea karabelo ea aniline a batla a le thata. Hona joale, boholo ba bona ba tsepamisitsoe ka laboratoring le sethaleng sa tlhahiso e nyenyane Chaena, 'me karolo ea tšebeliso e nyenyane haholo. Ha se eona tataiso e ka sehloohong ea katoloso ea ketane ea indasteri ea lik'hemik'hale e tlase ea aniline.

Katoloso ea ketane e ntle ea indasteri ea lik'hemik'hale e sebelisang aniline joalo ka thepa e tala e kenyelletsa karabelo ea arylation, alkylation reaction, oxidation le nitrification reaction, cyclization reaction, aldehyde condensation reaction le complex combination reaction. Aniline e ka kenya letsoho liketsong tse ngata tsa lik'hemik'hale, 'me ho na le lisebelisoa tse ngata tse tlaase.
