Igama lomkhiqizo:Methyl ethyl ketone

Ifomethi Molecular:C4h8o

I-CO CHA:78-93-3

Isakhiwo samangqamuzana somkhiqizo:

Ukucaciswa:

Izakhiwo Zamakhemikhali:

I-methyl ethyl ketone iyindawo ehlanganisiwe ngefomula yamakhemikhali CH3COCCH2CH3 kanye nesisindo samangqamuzana esingu-72.11. Kuwuketshezi olungenamibala futhi olusobala olunephunga elifana ne-acetone. Iguquguquka kalula. Akunangqondo nge-ethanol, ether, i-benzene, chloroform kanye no-oyela. Sluble ezingxenyeni ezi-4 zamanzi, kepha i-solubity iyancipha lapho izinga lokushisa liyanda, futhi lingakha ingxube ye-azeotropic ngamanzi. Ubuthi obuphansi, i-LD50 (Rat, Oral) 3300mg / kg. Okuvuthayo, umusi ungakha inhlanganisela yokuqhuma ngomoya. Ukuhlushwa okuphezulu kwe-vapor kunezici zokubulala izinzwa.

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.
