N-hexane umusaruro
Ibyinshi mu bicuruzwa bya hexane byo mumahanga bifashisha inzira ya molekuline ya sikororo ya adsorption, nka Richfielcd (Richfield) na Watson (Watson) muri Reta zunzubumwe zamerika, ukoresheje raffinate yongeye gushyirwaho nkibikoresho fatizo, mugutunganya ibitanda bibiri cyangwa byinshi kugirango adsorption. Kanda desorption kugirango ubyare n-hexane.
Abenshi mu bakora uruganda rwa hexane bakoresha inzira ya hydrogenation distillation, igabanijwemo ubwoko bubiri:

Ubwa mbere, hydrogenation hanyuma ikosorwe.

Bizwi kandi nka pre-hydrogenation, ibikoresho fatizo bishyushya no guhanahana ubushyuhe, bigera ku bushyuhe bwa reaction, byinjira muri reaction ya hydrogenation, desulfurizasiya na dearomatisation reaction yakozwe na catalizator, amavuta ya solide hamwe nuruvange rwa hydrogène byinjira mukigega cyo gutandukana kugirango gitandukane , hydrogène isubirana, amavuta ya solvent muminara yo gucamo Kata mubicuruzwa byarangiye. Muri rusange, nyuma ya hydrogenation yibikoresho fatizo, iracitsemo ibice igabanywa muri n-hexane, nubundi bwoko butandukanye bwamavuta ya solvent. Akarusho nuko ibikoresho byose bibisi bitandukanijwe kandi bikagabanuka, bigakoresha neza buri gicuruzwa. Ikibi ni uko ishoramari ari rinini kandi ibikoresho bikoreshwa ni byinshi.

Icya kabiri, gukosora hanyuma hydrogenation.

Nanone byitwa post-hydrogenation, kubijyanye na n-hexane, ibikoresho fatizo byabanje gukatirwa muri hexane itavanze ya 66-69 ya distillation, ubuziranenge bwa hexane ya kijyambere bwateye imbere cyane, kandi kuva itsinda rya fenyl ari bikubiye muri n-hexane, hexane muri hexane itavanze Ibirimo nabyo biriyongera cyane, hanyuma bigakorerwa hydrodebenzene desulfurizasi kugirango bitange n-hexane nziza. Akarusho nuko ishoramari ari rito kandi gukoresha ibikoresho ni bike. Ikibi ni uko igice kidafite amazi kidakoreshwa neza.
