Chemical Properties:

Methyl ethyl ketone yog cov organic compound nrog cov tshuaj formula CH3COCH2CH3 thiab molecular hnyav 72.11. Nws yog cov kua tsis muaj xim thiab pob tshab nrog cov ntxhiab tsw zoo ib yam li acetone. Yooj yim volatile. Nws yog miscible nrog ethanol, ether, benzene, chloroform thiab roj. Soluble nyob rau hauv 4 qhov chaw ntawm dej, tab sis lub solubility txo thaum lub kub nce, thiab muaj peev xwm tsim azeotropic sib tov nrog dej. Tsawg toxicity, LD50 (rat, qhov ncauj) 3300mg / kg. flammable, vapor tuaj yeem tsim tawg sib xyaw nrog huab cua. High concentration ntawm vapor muaj cov tshuaj loog.

Daim ntawv thov:

Methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) yog cov organic hnyav ntawm cov tshuaj lom neeg tsawg, uas muaj nyob hauv ntau daim ntawv thov. Nws yog siv rau hauv kev lag luam thiab cov khoom lag luam ua cov kuab tshuaj rau cov nplaum, xim, thiab cov tshuaj ntxuav thiab ua cov kuab tshuaj de-waxing. Ib qho khoom siv ntuj tsim ntawm qee yam khoom noj, methyl ethyl ketone tuaj yeem tso tawm rau hauv ib puag ncig los ntawm cov hluav taws kub thiab hav zoov hluav taws. Nws kuj yog siv los ua ib qho khoom qab zib hauv cov khoom noj.

MEK yog siv los ua cov kuab tshuaj rau ntau lub txheej txheej, piv txwv li, yas, nplaum, nitrocellulose, thiab acrylic coatings. Nws yog siv nyob rau hauv cov xim Remover, lacquers, varnishes, tshuaj tsuag xim, sealers, glues, sib nqus tapes, luam ntawv inks, resins, rosins, tu tov, thiab rau polymerization. Nws muaj nyob rau hauv lwm yam khoom siv, piv txwv li, tsev neeg thiab kev nyiam ua cements, thiab cov khoom ntim ntoo. MEK yog siv rau hauv dewaxing lubricating roj, degreasing ntawm hlau, nyob rau hauv zus tau tej cov hluavtaws tawv, pob tshab ntawv thiab txhuas ntawv ci, thiab raws li ib tug tshuaj intermediate thiab catalyst. Nws yog ib qho extraction hnyav hauv kev ua cov khoom noj thiab cov khoom xyaw zaub mov. MEK kuj tseem siv tau los ua kom tsis muaj menyuam cov khoom siv phais thiab kho hniav.
Ntxiv rau nws qhov kev tsim khoom, ib puag ncig ntawm MEK suav nrog cov pa tawm los ntawm lub dav hlau thiab cov tshuab hluav taws xob sab hauv, thiab kev lag luam xws li gasification ntawm thee. Nws pom muaj ntau npaum li cas hauv cov pa luam yeeb. MEK yog tsim los ntawm biologically thiab tau raug txheeb xyuas raws li cov khoom ntawm microbial metabolism. Nws kuj tau pom nyob rau hauv cov nroj tsuag, kab pheromones, thiab tsiaj cov ntaub so ntswg, thiab MEK yog tej zaum ib tug me me khoom ntawm ib txwm mammalian metabolism. Nws ruaj khov nyob rau hauv cov xwm txheej zoo tib yam tab sis tuaj yeem tsim peroxides ntawm kev cia ntev ntev; tej no tej zaum yuav tawg.
