Kugwiritsa ntchito kwambiri n-hexane N-hexane ndi zabwino zosungunulira zopanda poizoni, zomwe zimagwiritsidwa ntchito kwambiri pochotsa mafuta a masamba, butyl, butadiene rabara organic synthesis, propylene, olefin polymerization, intermediates pharmaceutical, paint thiners, ndi kuyeretsa zitsulo pamwamba pa zida zamakina. Kukula ndi kugwiritsa ntchito kwakukulu kwa n-hexane Msika waukulu wa n-hexane umagwiritsidwa ntchito pamakampani opanga mafuta a masamba, omwe amapitilira 60% ya kuchuluka konse kwa n-hexane. Ntchito zambiri zotsalira zili m'mafakitale a rabara ndi mankhwala. Kumayambiriro kwa zaka za m’ma 1960, maiko otukuka a Kumadzulo monga ku Ulaya ndi United States nthaŵi zambiri ankalimbikitsa “njira ya leaching” pakupanga mafuta a masamba. Kuphatikiza pakuchotsa mafuta pang'ono, mafuta odyedwa padziko lonse lapansi opangidwa ndi "njira yotsitsa" atenga 95% ya msika. Pakadali pano, popanga mafuta odyedwa padziko lonse lapansi, n-hexane ndiye chosungunulira chachikulu popanga mafuta odyedwa. Zachidziwikire, makampani ochepa amafuta ku Japan ndi South Korea amagwiritsa ntchito isohexane ngati zosungunulira. Kuyambira kumapeto kwa zaka za m'ma 1980, China idayamba kulimbikitsa mwamphamvu kugwiritsa ntchito n-hexane ngati chosungunulira chamafuta a masamba. Makhalidwe a hexane leaching process: Mtundu wa distillation wa hexane ndi waufupi, zosungunulira ndi zovulaza zimatenthedwa bwino, zakudya zamafuta amasamba sizimawonongeka ndi kutentha kwakukulu, chitetezo chamafuta odyedwa chimakulitsidwa, komanso kugwiritsa ntchito zosungunulira zochepa, kutsika. zotsalira, zokolola zambiri zamafuta, zosavuta kupanga mafakitale. Pakadali pano, makampani aku China omwe amapeza ndalama zothandizira ndalama komanso ophatikizana komanso opangira mafuta achinsinsi amagwiritsa ntchito n-hexane ngati chosungunulira. Makampaniwa amapanga mafuta opitilira 90% pamsika wapakhomo. Kugwiritsa ntchito n-hexane ngati zosungunulira zosungunulira zamasamba ndizofunikira kwambiri boma pamakampani opanga mafuta odyeka komanso miyezo yapamwamba yazinthu. Chifukwa chake, n-hexane yakhala chinthu chosungunulira chomwe chimagwiritsidwa ntchito kwambiri pokonza mafuta, omwenso ndi hexane yapakhomo komanso yakunja m'zaka zaposachedwa. Kuposa No. 6 zosungunulira mafuta, butane ndi zosungunulira ena akhala ofunika kwambiri mitundu ya masamba mafuta leaching zosungunulira. Mfundo ina ndi yakuti mumakampani opanga mafuta a masamba, n-hexane ali ndi gawo lapadera komanso losasinthika. N-hexane ali ndi mutu wa "mfumu ya m'zigawo". Pakadali pano, palibe zosungunulira zomwe zatha kupitilira n-hexane pochotsa.

Njira yopanga N-hexane Zambiri za hexane zakunja zimagwiritsa ntchito njira zotsatsira ma molecular sieve, monga Richfielcd (Richfield) ndi Watson (Watson) ku United States, pogwiritsa ntchito raffinate yopangidwanso ngati zopangira, pokonzanso mabedi awiri kapena kuposerapo kuti adsorption. Dinani desorption kuti mupange n-hexane. Ambiri opanga hexane apakhomo amagwiritsa ntchito njira ya hydrogenation distillation, yomwe imagawidwa m'mitundu iwiri: Choyamba, hydrogenation ndiye kukonza. Amatchedwanso chisanadze hydrogenation, zopangira ndi mkangano ndi kutentha kuwombola, kufika anachita kutentha, amalowa hydrogenation riyakitala, desulfurization ndi dearomatization anachita pansi pa zochita za chothandizira, zosungunulira mafuta ndi osakaniza wa hydrogen kulowa mu thanki kulekana kwa kulekana. , hydrogen kuchira, zosungunulira mafuta mu fractionation nsanja Dulani mu zomalizidwa. Nthawi zambiri, pambuyo hydrogenation ya zopangira, akadali fractionated ndi kudula mu n-hexane, ndi mitundu yosiyanasiyana ya zosungunulira mafuta. Ubwino wake ndiwakuti zida zonse ndizochepa komanso zatha, kugwiritsa ntchito bwino chilichonse. Choyipa chake ndi chakuti ndalamazo zimakhala zazikulu komanso kugwiritsa ntchito zinthu zambiri. Chachiwiri, rectification ndiye hydrogenation. Zomwe zimatchedwanso post-hydrogenation, pa nkhani ya n-hexane, zopangira zimadulidwa koyamba mu hexane yaiwisi ya 66-69 distillation range, chiyero cha hexane yaiwisi chimakhala bwino kwambiri, ndipo popeza gulu la phenyl ndi zomwe zili mu n-hexane, hexane mu hexane yaiwisi Zomwe zili nazo zimachulukitsidwa kwambiri, kenako zimayikidwa ndi hydrodebenzene desulfurization kuti apange n-hexane wapamwamba kwambiri. Ubwino wake ndikuti ndalamazo ndizochepa komanso kugwiritsa ntchito zinthu kumakhala kochepa. Choyipa ndichakuti gawo la unhydrogenated siligwiritsidwa ntchito moyenera.
