Ha e le hantle, tsoelo-pele ea tšebeliso ea li-intermediates e na le mefuta e mengata, e itseng e bohareng e sebelisoang ho dae e bitsoang dye intermediates, 'me e sebelisoa ho chefo e bolaeang likokoanyana, meriana le e bitsoang chefo e bolaeang likokoanyana, meriana ea meriana. Li-Intermediates li lokela ho nkoa e le lekala la indasteri e ntle ea lik'hemik'hale ka kakaretso, ha ea lokela ho aroloa ka thata ka li-dyestuff intermediates, li-intermediates tse bolaeang likokoanyana, li-intermediates tsa meriana ke indasteri, e leng ho tla fokotsa boholo ba tšebeliso ea li-intermediates tse ling le ho ama tsoelo-pele ea eona.

Patlisiso e ntle ea li-intermediates tsa lik'hemik'hale e tšoauoa ka mefuta e mengata e fapaneng, ntle le mefuta e 'maloa ea tekanyo ea tlhahiso e kholo haholo, mefuta e mengata ea lithane tse ngata ha e kholo haholo, empa mokhoa oa ho itokisa hangata o rarahane, o kenyelletsang likarolo tse ngata tsa likarolo le mokhoa oa ho arohana. , tlhahiso e ile ea boela ea hlahisa palo e kholo ea "litšila tse tharo" tse lokelang ho tšoaroa hantle. Ka hona, re lokela ho etsa lipatlisiso tsa letoto la lihlahisoa le ho hlophisa tlhahiso ea li-intermediate ka mokhoa o utloahalang e le hore re fumane melemo e metle.

Ho tloha maemong a linaha tsa kantle, lipatlisiso le tlhahiso ea li-intermediates li na le ho tsepamisa maikutlo hantle ho fihlela tlhahiso ea letoto, sete sa lisebelisoa tsa tlhahiso se ka hlahisa mefuta e mengata ho isa ho e leshome le metso e 'meli ea li-intermediates, lipatlisiso tse joalo le tlhahiso ka nts'etsopele e akaretsang, ts'ebeliso ea thekenoloji e ncha e bonolo ho e kenya ts'ebetsong, e tla finyella habeli sephetho ka halofo ea boiteko. Boemo ba Japane bo ka ba bakeng sa litšupiso tsa rona, tlhahiso ea pele ea li-intermediates Japane e boetse e hasane haholo, ho tloha lilemong tsa bo-1960 e bile makhetlo a supileng ho lokisa, ho tsepamisa maikutlo.

Ka phetoho le nts'etsopele, indasteri ea ho daea le pigment intermediates ea Chaena e fihlile boemong bo phahameng ka tekanyo ea tlhahiso, theknoloji le boemo ba lisebelisoa, tse ke keng tsa finyella litlhoko tsa nts'etsopele ea indasteri ea ho daea le ea pigment, empa hape e fana ka li-intermediates tsa boleng bo phahameng. bakeng sa linaha tse ling.

Lisebelisoa tse tala tse hlokahalang bakeng sa ho qaptjoa ha li-intermediate li fumaneha haholo lihlahisoa tsa petroleum le indasteri ea lik'hemik'hale tsa coking, tseo boholo ba tsona e leng benzene, naphthalene, anthraquinone, hammoho le metsoako e meng ea heterocyclic, le li-pigments tse entsoeng ka metsoako ea heterocyclic. ho phahama lilemong tsa morao tjena. Ho phaella moo, phenanthrene, pyridine, oksijene fluorene, quinoline, indole, carbazole, letoto la li-biphenyl tsa metsoako, lisebelisoa tsena tse rarahaneng tse sebelisoang ho etsa lidae, joale tšebeliso ea lihlahisoa tse tala e tla ba e pharaletseng le ea bokahohle.

Ea bobeli, hangata ho sebelisoa lik'hemik'hale tsa intermediates
