Ts'ebetso ea tlhahiso ea N-hexane
Bongata ba tlhahiso ea hexane e tsoang kantle e sebelisa mekhoa ea papatso ea limolek'hule tsa sieve, joalo ka Richfielcd (Richfield) le Watson (Watson) United States, ho sebelisoa raffinate e tsosolositsoeng joalo ka thepa e tala, ka ho sebelisa libethe tse peli kapa ho feta bakeng sa papatso. Tobetsa desorption ho hlahisa n-hexane.
Boholo ba baetsi ba hexane ba malapeng ba sebelisa mokhoa oa hydrogenation distillation, o arotsoeng ka mefuta e 'meli:

Taba ea pele, hydrogenation ebe e lokisoa.

E boetse e tsejoa e le pre-hydrogenation, thepa e tala e futhumatsoa ke phapanyetsano ea mocheso, e fihla mocheso oa karabelo, e kena ka har'a hydrogenation reactor, desulfurization le dearomatization reaction tlas'a ts'ebetso ea catalyst, oli ea solvent le motsoako oa hydrogen li kena ka tanka ea karohano bakeng sa karohano. , ho hlaphoheloa ha haedrojene, oli e qhibilihang ka har'a tora ea ho arola Khaola lihlahisoa tse felileng. Ka kakaretso, ka mor'a hore hydrogenation ea lisebelisoa tse tala, e ntse e arotsoe 'me e khaotsoe ka n-hexane, le mefuta e meng e fapaneng ea oli ea solvent. Monyetla ke hore lisebelisoa tsohle tse tala li fokotsehile ebile li felile, li sebelisa sehlahisoa ka seng ka botlalo. Bothata ke hore letsete le leholo le tšebeliso ea thepa e holimo.

Ea bobeli, rectification joale hydrogenation.

E boetse e bitsoa post-hydrogenation, tabeng ea n-hexane, thepa e tala e qala ho khaoloa ka har'a hexane e tala ea 66-69 distillation range, bohloeki ba hexane e tala bo ntlafala haholo, 'me kaha sehlopha sa phenyl se e ka har'a n-hexane, hexane ka har'a crude hexane Litaba le tsona li eketsehile haholo, 'me li kenngoa ka hydrodebenzene desulfurization ho hlahisa n-hexane ea boleng bo holimo. Molemo ke hore letsete le nyenyane le tšebeliso ea thepa e nyenyane. Bothata ke hore karolo ea unhydrogenated ha e sebelisoe ka katleho.
