Inkcazo:

Iipropati zeMichiza:

I-Methyl ethyl ketone yi-organic compound kunye ne-chemical formula CH3COCH2CH3 kunye ne-molecular weight of 72.11. Ilulwelo olungenambala noluselubala olunevumba elifana ne-acetone. Iguquguquka ngokulula. Iyaxubana ne-ethanol, i-ether, ibenzene, i-chloroform kunye neoli. Inyibilika kwiindawo ezi-4 zamanzi, kodwa ukunyibilika kuncipha xa ubushushu bunyuka, kwaye bunokwenza umxube we-azeotropic ngamanzi. Ubuthi obuphantsi, i-LD50 (i-rat, ngomlomo) 3300mg / kg. unokutsha, umphunga unokwenza umxube oqhumayo kunye nomoya. Uxinzelelo oluphezulu lomphunga luneempawu ze-anesthetic.

Isicelo:

I-Methyl ethyl ketone (i-2-butanone, i-ethyl methyl ketone, i-methyl acetone) i-solvent ye-organic ye-toxicity ephantsi, efumaneka kwizicelo ezininzi. Isetyenziswa kwiimveliso zoshishino kunye nezorhwebo njenge-solvent ye-adhesives, iipeyinti, kunye nee-agent zokucoca kunye ne-solvent de-waxing. Ilungu lendalo lokutya okuthile, i-methyl ethyl ketone inokukhutshwa kwindawo engqongileyo ngeentaba-mlilo kunye nomlilo wehlathi. Isetyenziselwa ukwenziwa komgubo ongenomsi kunye ne-synthetic resins engenambala, njenge-solvent, kunye ne-insurface coating. Ikwasetyenziswa njengencasa yencasa ekutyeni.

I-MEK isetyenziselwa ukunyibilikisa kwiinkqubo ezahlukeneyo zokugquma, umzekelo, i-vinyl, i-adhesives, i-nitrocellulose, kunye neengubo ze-acrylic. Isetyenziselwa ukususa ipeyinti, i-lacquers, ivanishi, iipeyinti zokutshiza, izitywini, iglue, iiteyiphu zemagneti, ii-inki zokuprinta, iireyini, iirosin, izisombululo zokucoca, kunye nepolymerization. Ifumaneka kwezinye iimveliso zabathengi, umzekelo, iisamente zendlu kunye nezinto zokuzilibazisa, kunye neemveliso zokuzalisa iinkuni. I-MEK isetyenziselwa ukuthambisa ioyile yokuthambisa, ukuthotywa kwesinyithi, kwimveliso yesikhumba sokwenziwa, iphepha elicacileyo kunye nefoyile ye-aluminium, kwaye njengekhemikhali ephakathi kunye ne-catalyst. Sisinyibilikisi esikhuphayo ekusetyenzweni kokutya kunye nezithako zokutya. I-MEK inokusetyenziselwa ukuvala inzala kwizixhobo zotyando kunye nezixhobo zamazinyo.
Ukongeza ekwenziweni kwayo, imithombo yokusingqongileyo ye-MEK ibandakanya ukukhupha ijethi kunye neenjini zokutsha zangaphakathi, kunye nemisebenzi yefektri efana nokufakwa kwegesi yamalahle. Ifumaneka kwisixa esikhulu kumsi wecuba. I-MEK iveliswa ngokwebhayoloji kwaye ichongiwe njengemveliso ye-microbial metabolism. Kwakhona kufunyenwe kwizityalo, i-pheromones yezinambuzane, kunye nezicubu zezilwanyana, kwaye i-MEK mhlawumbi imveliso encinci ye-metabolism ye-mammalian eqhelekileyo. Izinzile phantsi kweemeko eziqhelekileyo kodwa inokwenza iiperoxides ekugcinweni ixesha elide; ezi zinokugqabhuka.
