Taw qhia
Bromoacetone, tseem hu ua malondione bromine. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm bromoacetone:
Zoo:
Cov tsos mob: cov kua tsis muaj xim, nrog cov ntxhiab tsw tshwj xeeb.
Qhov ceev: 1.54 g / cm³
Solubility: Bromoacetone yog soluble nyob rau hauv ntau cov organic solvents xws li ethanol thiab ether.
Siv:
Organic synthesis: bromoacetone feem ntau yog siv los ua reagent hauv cov organic synthesis thiab tuaj yeem siv los ua ketones thiab cawv.
Txoj kev:
Bromoacetone feem ntau yog npaj raws li hauv qab no:
Bromide acetone method: Bromoacetone tuaj yeem npaj tau los ntawm kev ua haujlwm acetone nrog bromine.
Acetone cawv txoj kev: Acetone thiab ethanol yog reacted, thiab ces acid catalyzed kom tau bromoacetone.
Cov ntaub ntawv kev nyab xeeb:
Bromoacetone muaj cov ntxhiab tsw ntxhiab thiab yuav tsum tau siv nrog rau kev ua pa thiab tsis txhob nqus nws cov vapors.
Bromoacetone yog cov kua ua kua thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab qhov kub thiab txias.
Tsis txhob sib cuag nrog cov oxidizing muaj zog kom tsis txhob muaj kev phom sij txaus ntshai.
Cov cuab yeej tiv thaiv tus kheej xws li hnab looj tes tiv thaiv tsim nyog, tsom iav, thiab khaub ncaws tiv thaiv yuav tsum hnav thaum siv.
Bromoacetone yuav tsum tau muab cia rau hauv lub thawv airtight, kom deb ntawm cov hluav taws kub thiab cov khoom siv hluav taws xob.
Thov nco ntsoov ua raws li cov txheej txheem kev nyab xeeb kom raug thaum tuav cov tshuaj thiab raws li kev taw qhia ntawm cov kws tshaj lij.
