Acetoneyog cov kua tsis muaj xim, tsis muaj kuab lom uas yog miscible nrog dej thiab soluble hauv ntau cov kuab tshuaj organic.Nws yog siv dav hauv kev lag luam hnyav nrog ntau yam kev siv hauv tshuaj, tshuaj, tshuaj pleev ib ce, thiab lwm yam lag luam.Hauv tsab xov xwm no, peb yuav tshawb nrhiav yuav ua li cas ua acetone hauv chav kuaj los ntawm cov lus qhia ua ntu zus thiab nws cov peev xwm siv tau.

Ua Acetone hauv Lab

Muaj ntau ntau txoj hauv kev los ua acetone hauv chav kuaj.Ib txoj hauv kev zoo tshaj plaws yog oxidation ntawm acetone siv manganese dioxide ua cov oxidant.Nov yog cov lus qhia ua ntu zus los ua acetone hauv chav kuaj:

Kauj Ruam 1: Sau cov khoom siv thiab cov khoom siv: Koj yuav xav tau manganese dioxide, acetone, condenser, cua sov mantle, sib nqus stirrer, peb-caj dab, thiab khob iav haum rau siv hauv chav kuaj.

Kauj Ruam 2: Ntxiv ob peb gram ntawm manganese dioxide rau hauv lub khob peb-caj dab thiab muab tso rau hauv lub tshuab cua sov kom txog thaum nws yaj.

Kauj Ruam 3: Ntxiv ob peb tee ntawm acetone rau hauv lub hwj thiab do zoo.Nco ntsoov tias cov tshuaj tiv thaiv yog exothermic, yog li ceev faj kom tsis txhob kub ntau dhau.

Kauj Ruam 4: Txuas ntxiv cov sib tov rau li 30 feeb lossis kom txog thaum cov roj evolution nres.Qhov no qhia tias cov tshuaj tiv thaiv tiav.

Kauj Ruam 5: Txias qhov sib tov rau hauv chav sov thiab hloov mus rau qhov sib cais.Cais cov theem organic los ntawm theem aqueous.

Kauj ruam 6: Qhuav lub organic theem siv magnesium sulfate thiab lim nws los ntawm txoj kev luv luv lub tshuab nqus tsev lim kom tshem tawm cov impurities.

Kauj Ruam 7: Distilled cov acetone siv lub chaw kuaj sim distillation yooj yim.Sau cov feem uas phim cov ntsiab lus kub ntawm acetone (txog 56°C) thiab sau lawv rau hauv lub thawv tsim nyog.

Kauj Ruam 8: Ntsuam xyuas qhov purity ntawm cov acetone sau los ntawm kev tshuaj ntsuam xyuas tshuaj thiab spectrographic tsom xam.Yog tias qhov purity txaus siab, koj tau ua tiav acetone hauv chav kuaj.

Muaj peev xwm siv cov Lab-Made Acetone

Lab-ua acetone tuaj yeem siv rau ntau lub hom phiaj.Nov yog qee qhov kev siv tau zoo:
