Acetoneyog ib hom organic hnyav, uas yog dav siv nyob rau hauv ntau yam lag luam. Nws cov txheej txheem ntau lawm yog qhov nyuaj heev thiab yuav tsum muaj ntau yam kev cuam tshuam thiab kev ua kom huv. Hauv tsab xov xwm no, peb yuav txheeb xyuas cov txheej txheem tsim khoom ntawm acetone los ntawm cov khoom siv raw rau cov khoom.

Ua ntej tshaj plaws, cov khoom siv raw ntawm acetone yog benzene, uas tau los ntawm cov roj los yog thee tar. Benzene ces reacted nrog chav nyob rau hauv ib tug high-kub thiab high-pressure reactor los tsim ib tug sib tov ntawm cyclohexane thiab benzene. Cov tshuaj tiv thaiv no yuav tsum tau ua nyob rau ntawm qhov kub ntawm 300 degrees Celsius thiab lub siab ntawm 3000 psi.

Tom qab cov tshuaj tiv thaiv, qhov sib tov yog txias thiab muab faib ua ob ntu: cov roj txheej rau saum thiab txheej dej hauv qab. Cov roj txheej muaj cyclohexane, benzene thiab lwm yam khoom siv, uas yuav tsum tau ua kom huv ntxiv kom tau txais cov ntshiab cyclohexane.

Ntawm qhov tod tes, txheej dej muaj acetic acid thiab cyclohexanol, uas tseem yog cov khoom tseem ceeb rau kev tsim cov acetone. Hauv cov kauj ruam no, acetic acid thiab cyclohexanol raug cais tawm ntawm ib leeg los ntawm distillation.

Tom qab ntawd, acetic acid thiab cyclohexanol yog tov nrog concentrated sulfuric acid los tsim cov tshuaj tiv thaiv loj uas muaj acetone. Cov tshuaj tiv thaiv no yuav tsum tau nqa tawm ntawm qhov kub ntawm 120 degrees Celsius thiab lub siab ntawm 200 psi.

Thaum kawg, cov tshuaj tiv thaiv huab hwm coj sib cais los ntawm kev sib xyaw los ntawm kev distillation, thiab cov ntshiab acetone tau nyob rau sab saum toj ntawm kem. Cov kauj ruam no tshem tawm cov impurities ntxiv xws li dej thiab acetic acid, kom ntseeg tau tias acetone ua tau raws li cov qauv kev lag luam.

Hauv kev xaus, cov txheej txheem tsim khoom ntawm acetone yog qhov nyuaj heev thiab yuav tsum muaj qhov kub thiab txias, siab thiab ua kom huv si kom tau txais cov khoom zoo. Tsis tas li ntawd, cov khoom siv raw benzene kuj tau txais los ntawm cov roj los yog thee tar, uas muaj qee yam cuam tshuam rau ib puag ncig. Yog li ntawd, peb yuav tsum xaiv txoj hauv kev ruaj khov los tsim acetone thiab txo nws qhov cuam tshuam rau ib puag ncig ntau li ntau tau.
