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, potoloho ea indasteri ho feta Europe, United States le Japane le Korea Boroa le Korea Boroa e khutsufatsoa haholo, e leng Europe le United States le linaheng tse ling. e hloka lilemo tse mashome ho fihla boemong bo phahameng, indasteri ea lik'hemik'hale ea Chaena ka lilemo tse 'maloa feela e felile. Phapang ke hore ka mor'a sethala se seholo sa indasteri ea lik'hemik'hale Europe le United States, palo ea lihlahisoa tse ntle tsa lik'hemik'hale tse tšehetsoeng ke theknoloji e phahameng e eketsehile haholo, ha Chaena, ka lebaka la tsoelo-pele e fokolang ea theknoloji, 'maraka. boleng ba phepelo ea lik'hemik'hale tse ntle bo eketsehile butle.

O lumela hore 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 ntlafatso e tla potlakisa. Hajoale, ho na le litsi tse ngata tsa lipatlisiso tsa malapeng, haholo-holo tse amanang le likhoebo tse etellang pele, li ntse li eketsa matsete a lipatlisiso le nts'etsopele ea lik'hemik'hale tse ntle.

Bakeng sa tataiso ea nts'etsopele ea lik'hemik'hale tse ntle tsa China, Pingtou Mor'abo rōna o ile a akaretsa lintlha tse latelang, pele, tšebeliso ea li-hydrocarbon tse tlaase-khabone e le lisebelisoa tse tala bakeng sa lipatlisiso tse tebileng tsa tataiso ea ts'ebetso, ho theosa le noka ho tsepamisitse maikutlo ho li-intermediates tsa meriana, li-intermediates 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 ho tlase ho lisebelisoa tse phahameng tsa lik'hemik'hale tse ntle, lithuso le masimo a mang; Ea boraro, bakeng sa karohano le tlhoekiso ea lihlahisoa tse tala tsa carbon hydrocarbon le ts'ebetso e tebileng le ts'ebeliso, ho ea tlaase masimong a li-surfactants le li-plasticizers.

Ho ea ka pono ea litšenyehelo, katoloso ea indasteri e ntle ea lik'hemik'hale ea thepa e tala ea khabone e tlase ke mokhoa o theko e tlase haholo oa tlhahiso le lipatlisiso hajoale. Hajoale, litsi tse ngata tsa lipatlisiso tsa mahlale Chaena li ntse li tsoela pele ho atolosa lipatlisiso tsa lik'hemik'hale tse tlaase tsa carbon hydrocarbons. 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 ea ka lipatlisiso tsa pele, ketane ea indasteri ea lik'hemik'hale tse ntle tse fetang 50 sebakeng se tlaase sa isobutylene e hloekileng e atolositsoe, 'me ketane ea indasteri ea lihlahisoa tse tlaase e na le tekanyo e phahameng ea ntlafatso. Ho na le mefuta e fetang 60 ea lik'hemik'hale tse ntle ka tlase ho katoloso ea ketane ea indasteri ea aniline, le litaelo tse ngata tse tlase tsa ts'ebeliso.

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 tlase ho MDI, lisebelisoa tsa rabara, lidae le li-intermediate tsa meriana, li-additives tsa peterole le masimo a mang. Lik'hamphani tsa benzene tse hloekileng le tse hlahisang lik'hemik'hale ha li khone ho kopanngoa le lihlahisoa tsa oli, tse khothalletsang katoloso le ts'ebeliso ea ketane e tlase ea liindasteri ea benzene e hloekileng, 'me e fetohile sepheo sa indasteri ea lipatlisiso le nts'etsopele ea lik'hemik'hale.

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

Sebakeng sa rabara accelerator le antioxidant tshebediso, aniline tlase noka tšimong ea rabara ke ea bohlokoa tshebediso tataiso, e ka bang 11% ya kakaretso ya tshebediso ya theosa le noka ea aniline, ka sehloohong moemeli lihlahisoa ke p-amino-diphenylamine le hydroquinone.

Har'a 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 hose, dae e qhalakaneng, hape e sebelisoa ho etsa lipente le li-pigments hape e le sesupo. P-hydroxyaniline e sebelisoa ho hlahisa sebabole sa FBG, acid e fokolang e khanyang ea 5G le lidae tse ling, ho etsoa ha paracetamol, antamine le lithethefatsi tse ling, empa hape e sebelisoa ho hlahisa baetsi, li-antioxidants joalo-joalo.

Ho latela lipatlisiso, hajoale, metsoako ea aniline e sebelisoang indastering ea dae ea China hangata 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 ts'ebeliso ea metsoako ea naetrojene. ho theosa le 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-trichloroaniline, n-acetoacetanilide, n-formylaniline, phenylurea, bisphenylurea, phenylthiourea le lihlahisoa tse ling. Ka lebaka la palo e kholo ea lihlahisoa tsa aniline halogenation, ho hakanngoa esale pele hore ho na le mefuta e ka bang 20, eo hape e fetohileng tataiso ea bohlokoa bakeng sa katoloso ea ketane e ntle ea indasteri ea lik'hemik'hale ea aniline.

Lihlahisoa tse tlase tse sebelisang halogenation ea aniline, joalo ka o-chloraniline, li sebelisetsoa tlhahiso ea sulfur blue FBG, lidae tse fokolang tsa acid e mosehla oa 5G, ho etsa paracetamol, antamine le lithethefatsi tse ling, empa hape le bakeng sa tlhahiso ea bahlahisi, li-antioxidants le tse ling. joalo-joalo. Diphenyl thiourea e sebelisoa ho hlahisa li-accelerator tsa vulcanization, li-capsules tsa vulcanization, lithaere tsa metsi, terata le cable, hammoho le meriana le li-intermediate tsa dae. N-acetoacetanilide e sebelisoa tlhahiso ea sulfonamides, analgesics, antipyretic ice le preservatives, le rabara vulcanization accelerator.

Ho ea ka tlhahlobo e sa phethoang, palo ea lihlahisoa tsa lik'hemik'hale tsa aniline halogenated ka tlaase ho metsi li na le hoo e ka bang 40% ea palo ea lik'hemik'hale tsa aniline tse tlaase, empa lihlahisoa li sebelisoa haholo libakeng tse phahameng, 'me tekanyo ea kakaretso ha e kholo. Ka nts'etsopele e matla ea lefapha la meriana, lipatlisiso tsa tekheniki tsa aniline halogenation le tsona li fetohile tataiso ea bohlokoa ea nts'etsopele ea lipatlisiso le nts'etsopele ea mahlale a China.

Boitšoaro bo bong ba bohlokoa ba aniline ke karabelo ea phokotso, joalo ka aniline le hydrogen ho hlahisa cyclohexane, aniline le concentrated sulfuric acid le soda ash ho hlahisa dicyclohexane, aniline le sulfuric acid le sulfur trioxide ho hlahisa p-aminobenzenesulfonic acid. Karabelo ea mofuta ona e hloka lisebelisoa tse ngata tse thusang, 'me palo ea lihlahisoa tse tlase ha e kholo,' me ho hakanngoa hore ho na le lihlahisoa tse ka bang hlano. 

Har'a tsona, tse kang p-aminobenzenesulfonic acid, ho etsa lidae tsa azo, joalo-joalo, tse sebelisoang e le reagent ea litšupiso, reagent ea liteko le chromatographic analysis reagent, hape e ka sebelisoa e le chefo e bolaeang likokoanyana ho thibela lefu la mafome a koro. Dicyclohexylamine, ke ho lokisoa ha dae intermediates, hammoho le chefo e bolaeang likokoanyana textile mafome a koro, le ho lokisetsa linoko.

Maemo a phokotso ea karabelo ea aniline a batla a le thata, 'me hajoale, China e tsepamisitse maikutlo haholo laboratoring le sethaleng sa tlhahiso e nyane, mme karolo ea tšebeliso e nyane haholo, eo e seng eona tataiso e ka sehloohong ea katoloso ea lik'hemik'hale tse ntle tse tlase. ketane ea indasteri ea aniline.

Tšebeliso ea aniline e le thepa e tala ea katoloso e ntle ea indasteri ea lik'hemik'hale, ho na le karabelo ea arylation, alkylation reaction, oxidation le nitrification reaction, cyclization reaction, aldehyde condensation reaction and complex combination reaction. Aniline e ka kenya letsoho liketsong tse ngata tsa lik'hemik'hale, 'me ho na le lisebelisoa tse ngata tse tlaase. re tla tsoelapele ho etsa tlhahlobo e itseng ea eona, ke kopa re e shebe ka thabo.
