Acetoneyog ib qho tsis muaj kob, cov kua uas tsis muaj ntxhiab nrog cov ntxhiab tsw muaj zog. Nws yog dav siv nyob rau hauv ntau yam kev lag luam, xws li cov tshuaj, roj av, tshuaj lom neeg, cov nplaum, pleev xim rau ntawm cov ntawv sau, peb yuav qhia cov khoom siv ua kom tau zoo.

Kev tsim cov acetone tsuas yog muaj ob kauj ruam: thawj kauj ruam yog los tsim cov acetone los ntawm kev txo acidic, thiab kauj ruam thib ob yog cais thiab purify acetone.

Nyob rau hauv thawj kauj ruam, acetic acid yog siv los ua cov khoom siv raw, thiab catalyst yog siv los ua cov tshuaj tiv thaiv catalytic kom tau acetone. Cov catalalys feem ntau yog zinc hmoov, hlau hmoov, thiab lwm yam. Cov tshuaj tiv thaiv cov tshuaj tiv thaiv yog li nram no: ch3cooh + h2Luam dej →Ch3coch3. Cov tshuaj ntsuam kub yog 150-250℃, thiab cov tshuaj tiv thaiv siab yog 1-5 MPa. Cov hmoov zinc thiab cov hmoov hlau tau tsim tsa tom qab cov tshuaj tiv thaiv thiab tuaj yeem siv ntau zaus.

Hauv kauj ruam thib ob, cov sib xyaw muaj acetone tau sib cais thiab huv. Muaj ntau txoj hauv kev rau kev sib cais thiab ua kom huv acetone, xws li distillation txujcation, kev nqus cov qauv, thiab lwm yam, cov txheej txheem distillation yog qhov feem ntau siv txoj kev. Cov qauv no siv cov ntsiab lus uas sib txawv ntawm cov tshuaj uas cais lawv los ntawm distillation. Acetone muaj qhov cub npau npau tsawg thiab lub siab vapor siab. Yog li ntawd, nws tuaj yeem sib cais los ntawm lwm cov tshuaj los ntawm distillation nyob rau hauv ib tug siab nqus ib puag ncig ntawm tsawg kub. Qhov sib cais acetone yog tom qab xa mus rau cov txheej txheem tom ntej rau kev kho ntxiv.

Hauv cov ntsiab lus, kev tsim cov acetone suav nrog ob kauj ruam: catalytic txo ntawm acetic acid kom tau acetone thiab sib cais thiab purification ntawm acetone. Acetone yog ib qho tseem ceeb ntawm cov khoom siv tshuaj lom neeg nyob hauv cov roj av, tshuaj lom neeg, tshuaj thiab lwm yam lag luam. Nws muaj ntau cov kev siv hauv kev ua liaj ua teb ntawm kev lag luam thiab lub neej. Ntxiv rau cov txheej txheem saum toj no, muaj lwm txoj hauv kev tsim acetone, xws li fermentation qauv thiab hydrogenation txoj kev. Cov hau kev no muaj lawv tus cwj pwm thiab cov txiaj ntsig zoo hauv cov ntawv thov sib txawv.
