Isakhiwo samangqamuzana somkhiqizo:

Ukucaciswa:

Izakhiwo Zamakhemikhali:

I-Methyl ethyl ketone itholakala ekuphendukeni okuhlukahlukene ngenxa yeqembu layo le-carbonyl kanye ne-hydrogen esebenzayo eduze kweqembu le-carbonyl. Ukuvuselelwa kwenzeka lapho kufuthelwa nge-hydrochloric acid noma i-sodium hydroxide ukukhiqiza ama-3,4-dimethyl-3-hexen-2-hesyl-3-heipten-5-Einpten-5-munye. Lapho kuvezwa ukukhanya kwelanga isikhathi eside, kukhiqizwa imikhiqizo ye-ethane, acetic acid nemikhiqizo ye-conderations. Khiqiza i-Diacetyl lapho oxidised nge-nitric acid. Lapho i-oxidised nge-oxidizing agents eqinile efana ne-chromic acid, kwenziwa i-acetic acid. I-Butanone iqinile ekushiseni, futhi ama-cleavage we-thermal emazingeni okushisa aphezulu akhiqiza i-enone noma i-methyl enikete. Lapho kuncishiswa ama-aldehyde a-aldehy noma ama-aromatic, ama-ketones aphezulu esisindo, amakhompiyutha akwa-cyclic, akhiqizwa ama-cendins. Isibonelo, ukuvumelanisa nge-formaldehyde ekubakhona kweSodium Hydroxide kuqala kukhiqize 2-Methyl-1-Butanol-3-One, kulandelwe ukuphuma komzimba ku-Methacrrylatone.
Ukulungiswa kwe-resinization kwenzeka lapho kuvezwa ukukhanya kwelanga noma ukukhanya kwe-UV. Ukuvuselelwa nge-Phenol Kuvulwa 2,2-BIS (4-HydroxyphenHenyl) Butane. Iphendula ngama-aliphatic espers phambi kwe-catalyst eyisisekelo ukukhiqiza ama-β-diketones. Ukuhlonya nge-anhydride acidic phambi kwe-catalyst ye-acidic ukwakha ama-β-diketones. Iphendula nge-hydrogen Cyanide ukwakha i-Cyanohydrin. Iphendula nge-ammonia ukwakha ama-ketopiperidine derivatives. I-athomu ye-α-hydrogen yeButanone ithathwe kalula ngama-halogens ukwakha ama-ketoone ahlukahlukene ane-halogenated, njenge-3-chloro-2-buthananone ngokuxhumana ne-chlorine. Ukuxhumana ne-2,4-dinitrofenhydrazine kukhiqiza ephuzi 2,4-dinitrofenhydrazone.

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.
