Acetone yog siv dav siv cov kuab tshuaj organic nrog ntau hom kev lag luam, suav nrog cov xim, cov nplaum, thiab cov khoom siv hluav taws xob. Isopropyl cawv kuj yog ib qho hnyav hnyav siv nyob rau hauv ntau yam kev tsim khoom. Hauv tsab xov xwm no, peb yuav tshawb xyuas seb acetone puas tuaj yeem tsim los ntawm isopropyl cawv.
Thawj txoj hauv kev hloov pauv isopropyl cawv rau acetone yog los ntawm cov txheej txheem hu ua oxidation. Cov txheej txheem no cuam tshuam nrog cov cawv nrog oxidizing tus neeg sawv cev, xws li oxygen lossis peroxide, hloov nws mus rau hauv nws cov ketone sib raug. Nyob rau hauv cov ntaub ntawv ntawm isopropyl cawv, lub resulting ketone yog acetone.
Txhawm rau ua tiav cov tshuaj tiv thaiv no, cov isopropyl cawv yog tov nrog cov roj inert xws li nitrogen lossis argon nyob rau hauv muaj cov catalyst. Cov catalyst siv nyob rau hauv cov tshuaj tiv thaiv no feem ntau yog hlau oxide, xws li manganese dioxide los yog cobalt (II) oxide. Cov tshuaj tiv thaiv tom qab ntawd tso cai rau mus rau qhov kub thiab txias.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv isopropyl cawv ua cov khoom pib ua acetone yog tias nws pheej yig dua piv rau lwm txoj hauv kev tsim acetone. Tsis tas li ntawd, cov txheej txheem tsis tas yuav tsum tau siv cov reactive reagents los yog cov tshuaj txaus ntshai, ua rau nws muaj kev nyab xeeb thiab zoo ib puag ncig.
Txawm li cas los xij, kuj tseem muaj qee qhov teeb meem cuam tshuam nrog txoj kev no. Ib qho ntawm cov teeb meem tseem ceeb yog cov txheej txheem yuav tsum muaj qhov kub thiab txias, ua rau nws siv zog ntau. Tsis tas li ntawd, cov catalyst siv nyob rau hauv cov tshuaj tiv thaiv yuav tsum tau hloov lub sij hawm los yog regenerated, uas yuav ua rau kom tag nrho cov nqi ntawm cov txheej txheem.
Hauv kev xaus, nws muaj peev xwm tsim acetone los ntawm isopropyl cawv los ntawm cov txheej txheem hu ua oxidation. Txawm hais tias txoj kev no muaj qee qhov zoo, xws li siv cov khoom pib pheej yig thiab tsis xav tau cov tshuaj reactive heev lossis cov tshuaj txaus ntshai, nws kuj muaj qee qhov tsis zoo. Cov kev cov nyom tseem ceeb suav nrog cov kev xav tau ntawm lub zog siab thiab xav tau kev hloov pauv raws sijhawm lossis rov tsim dua tshiab ntawm cov catalyst. Yog li ntawd, thaum xav txog kev tsim cov acetone, nws yog ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account tag nrho cov nqi, kev cuam tshuam ib puag ncig, thiab kev ua tau zoo ntawm txhua txoj hauv kev ua ntej txiav txim siab ntawm txoj kev tsim khoom tsim nyog tshaj plaws.
