Acetoneyog ib qho tsis muaj kob, cov kua tsis muaj kuab uas tsis meej nrog dej thiab soluble hauv ntau cov kuab tshuaj organic. Nws yog dav siv cov kuab cua muaj kuab nrog ntau cov ntawv thov hauv cov tshuaj, tshuaj, tshuaj pleev ib ce, thiab lwm yam kev lag luam. Hauv tsab xov xwm no, peb yuav tshawb txog yuav ua li cas thiaj ua tau Acetone hauv ib lub chaw sim los ntawm cov lus qhia ib qib zuj zus thiab nws cov peev txheej siv tau.

Ua acetone hauv ib qho lab)

Muaj ob peb txoj hauv kev los ua acetone hauv ib lub lab. Ib txoj hauv kev feem ntau cuam tshuam nrog oxidation ntawm acetone siv manganese dioxide ua cov oxidant. Ntawm no yog cov lus qhia ib qib zuj zus los ua acetone hauv ib lub lab:

Kauj Ruam 1: Sau cov ntaub ntawv xav tau thiab cov cuab yeej siv: koj yuav xav tau manganese dioxide, tus condensone, ib-caj dab treask, thiab khob iav haum rau siv nyob rau hauv ib lab.

Kauj Ruam 2: Ntxiv ob peb gram ntawm manganese dioxide rau peb-caj dab khob thiab tshav kub nws rau ntawm cov cua sov mantle kom txog thaum nws melts.

Kauj ruam 3: Ntxiv ob peb tee ntawm acetone rau lub khob dej thiab do zoo. Nco ntsoov tias cov kev tawm tsam yog exothermic exhermic, yog li yuav tsum ceev faj kom tsis txhob ua kom sov heev.

Kauj Ruam 4: Txuas ntxiv nplawm cov sib xyaw kom ntev li 30 feeb lossis kom txog thaum cov roj evolution nres. Qhov no qhia tau tias cov tshuaj tiv thaiv tau ua tiav.

Kauj Ruam 5: Txias qhov sib xyaw kom haum rau chav sov thiab hloov nws mus rau cais funnel. Cais cov theem organic los ntawm theem aqueous.

Kauj Ruam 6: Qhuav cov organic theem uas siv magnesium sulfate thiab lim nws los ntawm txoj kev lim dej lim kom tshem tawm tej kev cuam tshuam.

Kauj Ruam 7: univers lub acetone siv cov sim yooj yim sim distillation teeb. Sau cov leb feem uas phim qhov npau npau ntawm acetone (kwv yees li 56°C) thiab sau lawv rau hauv cov thawv uas tsim nyog.

Kauj Ruam 8: Ntsuas cov kev coj dawb huv ntawm cov acetone siv tshuaj ntsuam tshuaj lom neeg thiab tshuaj ntsuam xyuas. Yog hais tias lub purity yog txaus siab, koj tau ua tiav acetone hauv ib lub lab.

Muaj peev xwm siv cov acetone ua acetone

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