Igama lomkhiqizo:Methyl ethyl ketone

Ifomethi Molecular:C4h8o

I-CO CHA:78-93-3

Isakhiwo samangqamuzana somkhiqizo:

Ukucaciswa:

Izakhiwo Zamakhemikhali:

I-methyl ethyl ketone (i-mek) iwuketshezi olungenamibala ngephunga elichazwe njengobukhali, onamakha we-peppermint, noma i-acetone like. Kuyancibilika emanzini kuze kufike ku-28% ngesisindo futhi akunakuphikwa ngamanye ama-solvents amaningi aphilayo. Umkhawulo ophansi ongezansi ungo-1.4% futhi umkhawulo ongenhla wokuqhuma ngu-11.4%. I-methyl ethyl ketone ingahle ihambisane nama-oxidizers aqinile, ama-amonine, ama-ammonia, ama-inorganic acid, ama-caustics, isocyanates, nama-pyridines. Lapho kusetshenziswa insiza, i-methyl katone ye-methyl kumele iphathwe ngokuqapha, njengoba kuyi-class lb flamwable liquid niosh

Isicelo:

I-Methyl ethyl ketone (2-butanone, ethyl methyl ketone, i-methyl acetone) i-organic solvent yenobuthi obuphansi obuphansi, etholakala kwizicelo eziningi. Isetshenziswa emikhiqizweni yezimboni nezentengiso njenge-solvent yokunamathela, upende kanye nama-ejenti wokuhlanza kanye ne-solvent ye-de-waxing. Ingxenye yemvelo yokudla okuthile, i-methyltyl katone ingadedelwa emvelweni ngentaba-mlilo kanye ne-fires fires.it isetshenziswa ku-themanunciction of anemicrosoft an soundins, njenge-solvent, kanye ne-insurface coating. Iphinde isetshenziswe njenge-flavongsstance ekudleni.

I-MEK isetshenziswa njenge-solvent yezinhlelo ezahlukahlukene zenhlanganisela, ngokwesibonelo, i-vinyl, anamathela, ama-nitrocellulose, kanye nezingubo ze-acrylic. Isetshenziswa ekususeni ngopende, ama-lacquers, ama-varnish, amapende wokufafaza, ama-boiler, amathempeli amazibuthe, ama-rosin, ama-rosin, ama-rosin, ama-polymerization. Kutholakala kweminye imikhiqizo yabathengi, ngokwesibonelo, amakhekhe asendlini kanye ne-hobby, kanye nemikhiqizo yokugcwalisa izinkuni. I-MEK isetshenziswa ngamafutha okugcoba ukugcoba, ukushukela kwezinsimbi, ekukhiqizeni izimpaphe zokwenziwa, iphepha elibonakalayo ne-aluminium foil, futhi njengomphathi wamakhemikhali. Kuyinto ekhishwa i-solvent ekusebenzeni kokudla kanye nezithako zokudla. I-MEK nayo ingasetshenziswa ukuqinisa imishini yamazinyo.
Ngaphezu kokwenziwa kwayo, imithombo yezemvelo ye-MEK ibandakanya ukuqeda amandla kusuka ku-jet kanye nezinjini zokuhlangana zangaphakathi, kanye nemisebenzi yezimboni efana nokufakwa kwamalahle. Kutholakala ngamanani amakhulu entuthu kagwayi. I-MEK ikhiqizwa ngokomzimba futhi ikhonjwe njengomkhiqizo we-microbial metabolism. Kutholakale nasezitshalweni, ama-pheromones ezinambuzane, nezicubu zezilwane, futhi iMek cishe ingumkhiqizo omncane we-metabolian ejwayelekile ye-mammalian. Kuzinzile ngaphansi kwezimo ezijwayelekile kepha kungakha ama-peroxides kwisitoreji eside; Lokhu kungaqhuma.
