Acetoneke mofuta oa solvent ea manyolo, e sebelisoang haholo liindastering tse fapaneng. Ts'ebetso ea eona ea tlhahiso e rarahane haholo 'me e hloka mekhoa e fapaneng ea liketso le mehato ea ho hloekisa. Sehloohong sena, re tla sekaseka ts'ebetso ea tlhahiso ea acetone ho tloha lihlahisoa tse tala ho ea ho lihlahisoa.
Pele ho tsohle, thepa e tala ea acetone ke benzene, e fumanoang ka oli kapa sekontiri sa mashala. Benzene ebe e ts'oaroa ka mouoane ka har'a mochini oa mocheso o phahameng le oa khatello e phahameng ho hlahisa motsoako oa cyclohexane le benzene. Boitšoaro bona bo hloka ho etsoa ka mocheso o phahameng oa likhato tse 300 tsa Celsius le khatello e phahameng ea 3000 psi.
Ka mor'a karabelo, motsoako o pholile fatše 'me o arotsoe likarolo tse peli: lera la oli ka holimo le metsi a tlase. Lera la oli le na le cyclohexane, benzene le lintho tse ling, tse hlokang ho feta mehato ea tlhoekiso ho fumana cyclohexane e hloekileng.
Ka lehlakoreng le leng, lera la metsi le na le acetic acid le cyclohexanol, tseo hape e leng lisebelisoa tsa bohlokoa tsa tlhahiso ea acetone. Mothating ona, asiti ea acetic le cyclohexanol li arotsoe ho tse ling ka distillation.
Ka mor'a moo, acetic acid le cyclohexanol li kopantsoe le concentrated sulfuric acid ho hlahisa boima ba 'mele bo nang le acetone. Boitšoaro bona bo hloka ho etsoa ka mocheso o phahameng oa likhato tse 120 tsa Celsius le khatello e phahameng ea 200 psi.
Qetellong, boima ba karabelo bo arohanngoa le motsoako ka distillation, 'me acetone e hloekileng e fumanoa ka holim'a kholomo. Mohato ona o tlosa litšila tse setseng tse kang metsi le acetic acid, ho etsa bonnete ba hore acetone e finyella litekanyetso tsa indasteri.
Qetellong, ts'ebetso ea tlhahiso ea acetone e rarahane haholo 'me e hloka mocheso o tiileng, khatello le mehato ea ho hloekisa ho fumana lihlahisoa tsa boleng bo phahameng. Ho feta moo, benzene e tala e boetse e fumanoa ka oli kapa tar ea mashala, e nang le tšusumetso e itseng tikolohong. Ka hona, re lokela ho khetha mekhoa e tsitsitseng ea ho hlahisa acetone le ho fokotsa tšusumetso ea eona tikolohong ka hohle kamoo ho ka khonehang.
