1. Acetone rau kev lag luam dav siv feem ntau muaj cov khoom tsis huv xws li methanol, aldehydes thiab organic acids. Cov poov tshuaj permanganate hmoov ntxiv rau reflux thaum ua kom zoo. Tus nqi ntxiv yuav tsum khaws cov acetone ntshav. Yog tias nws tsis sov, nws tuaj yeem tso rau 3-4 hnub. Tom qab txias, lim tawm cov nag lossis daus, ntxiv cov dej tsis muaj poov tshuaj carbonate lossis calcium chloride kom lub cev qhuav dej thiab qhuav, thiab sau los ntawm kev sib cais.
2. Yog tias acetone tau sib xyaw nrog me me ntawm ethanol, ether, chloroform thiab lwm yam kuab tshuaj, ntxiv ob zaug ntawm cov kua sodium saturated bisulfite tov thiab co thaum lub sij hawm kho kom tsim tau sodium bisulfite acetone adduct, thiab tom qab ntawd ntxiv cov cawv tib yam rau nws txhawm rau txhawm rau txhawm rau ua kom muaju, Sau los ntawm kev lim dej, ntxuav nrog cawv thiab ether nyob rau hauv lem, thiab qhuav. Sib tov cov kua nplaum no nrog cov dej me me, ntxiv 10% sodium carbonate lossis 10% hydrochloric acid txhawm rau rhuav tshem cov khoom lag luam, faib ua feem me me lim dej, siv ib feem ntawm acetone, ntxiv anhydrous calcium chloride lossis potassium carbonate kom lub cev qhuav dej, thiab rov ua kom rov zoo dua. nws.
