Ib nyuag qhia rau zas xim intermediates

Dye intermediates, tseem hu ua intermediates, feem ntau hais txog ntau yam muaj ntxhiab hydrocarbon derivatives siv nyob rau hauv cov khoom lag luam ntawm cov xim av thiab cov xim lim xim. Lawv tau tsim los ntawm cov roj ntsha muaj ntxhiab hydrocarbons xws li benzene, toluene, naphthalene thiab anthracene los ntawm kev lag luam chemical chemical thiab petrochemical los ntawm cov txheej txheem ntawm cov organic synthesis chav ua haujlwm (saib cov txheej txheem tshuaj tiv thaiv). Nrog rau kev txhim kho kev lag luam chemical, daim ntawv thov ntau ntawm cov xim intermediates tau nthuav dav rau kev lag luam kws tshuaj, kev lag luam tshuaj tua kab, kev lag luam tawg lag luam, cov ntaub ntawv teev cia cov khoom lag luam, ntxiv rau cov pabcuam, surfactant, tshuaj tsw qab, yas, hluavtaws fiber ntau thiab lwm cov chaw tsim khoom. Muaj ntau ntau yam ntawm cov xim intermediates, thiab pua pua ntawm lawv yog qhov tseem ceeb dua. Qhov tshuaj pleev xim tseem ceeb tshaj plaws hauv lub sijhawm thaum ntxov, xws li nitrobenzene, aniline, phenol, chlorobenzene thiab phthalic anhydride, tau tsim los ua ib qho tseem ceeb cov organic intermediates vim lawv cov kev siv dav thiab ntau npaum li cas. Ntau tshaj 10,000 tons. Cov tshuaj pleev xim tshwj xeeb tshaj plaws tam sim no suav nrog o-nitrochlorobenzene, p-nitrochlorobenzene, o-nitrotoluene, p-nitrotoluene, 2-naphthol, anthracene, 1-aminoindole thiab lwm yam. Pib ntawm cov nruab nrab saum toj no, ib chav ntawm cov organic synthesis chav ua yuav siv tau los npaj ntau yam intermediates nrog cov txheej txheem nyuaj.
