Chemical Properties:

Methyl ethyl ketone inobatwa nemaitiro akasiyana-siyana nekuda kweboka rayo re carbonyl uye iyo inoshanda hydrogen iri padyo neboka re carbonyl.Condensation inoitika kana ichipisa nehydrochloric acid kana sodium hydroxide kugadzira 3,4-dimethyl-3-hexen-2-one kana 3-methyl-3-hepten-5-imwe.Kana yakavhenekerwa kuchiedza chezuva kwenguva yakareba, ethane, acetic acid uye condensation zvigadzirwa zvinogadzirwa.Gadzira diacetyl kana yakasanganiswa ne nitric acid.Kana yakasvibiswa neakasimba oxidizing agents akadai sechromic acid, acetic acid inogadzirwa.Butanone haina kugadzikana pakupisa, uye kupisa kutsemuka pakupisa kwepamusoro kunoburitsa enone kana methyl enone.Kana yakanyungudutswa nealiphatic kana anonhuwirira aldehydes, yakakwira molecular weight ketones, cyclic compounds, ketone condensation uye resins inogadzirwa.Semuenzaniso, condensation ne formaldehyde muhupo hwe sodium hydroxide inotanga kubudisa 2-methyl-1-butanol-3-imwe, inoteverwa nekushaya mvura kune methacrylatone.
Resinization inoitika pakusangana nechiedza chezuva kana UV mwenje.Condensation ne phenol inobereka 2,2-bis(4-hydroxyphenyl)butane.Inopindirana nealiphatic esters pamberi peiyo yakakosha catalyst kuburitsa β-diketones.Acylation ine acidic anhydride pamberi peiyo acidic catalyst kuumba β-diketones.Inokandwa nehydrogen cyanide kuumba cyanohydrin.Inopindirana neammonia kuumba ketopiperidine derivatives.Iyo α-hydrogen atomu yebutanone inotsiviwa nyore nyore nehalogens kuti iite akasiyana halogenated ketoni, senge 3-chloro-2-butanone nekudyidzana neklorini.Kudyidzana ne2,4-dinitrophenylhydrazine inogadzira yero 2,4-dinitrophenylhydrazone.

Application:

Methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) is organic solvent yeine low low toxicity, inowanikwa mumashandisirwo mazhinji.Inoshandiswa muzvigadzirwa zvemaindasitiri uye zvekutengesa sechinhu chinonyungudutsa chekunamira, pendi, nekuchenesa maajenti uye se de-waxing solvent.Chinhu chechisikigo chezvimwe zvikafu, methyl ethyl ketone inogona kuburitswa mumhepo nemakomo anoputika uye moto wesango. Inoshandiswa mukugadzira hupfu husina hutsi uye isina mavara ekugadzira resins, sechinhu chinonyungudutsa, uye insurface coating.Inoshandiswawo sechinhu chinonhuwira muchikafu.

MEK inoshandiswa sechinhu chinonyungudutsa kune akasiyana masisitimu ekuputira, semuenzaniso, vinyl, zvinonamira, nitrocellulose, uye acrylic coatings.Inoshandiswa mukubvisa pendi, lacquers, varnishes, pfapfaidzo pendi, sealers, glues, magineti matepi, kudhinda ingi, resin, rosins, kuchenesa mhinduro, uye polymerization.Inowanikwa mune zvimwe zvigadzirwa zvevatengi, semuenzaniso, simiti yemumba uye yekuzvivaraidza, uye zvigadzirwa zvekuzadza huni.MEK inoshandiswa mukudonhedza mafuta ekuzora, kupera kwesimbi, mukugadzirwa kwematehwe ekugadzira, mapepa akajeka uye aluminium foil, uye sekemikari yepakati uye inokonzeresa.Iyo inonyungudutsa yekubvisa mukugadziriswa kwechikafu uye zvigadzirwa zvekudya.MEK inogona zvakare kushandiswa kuchenesa yekuvhiya uye yemeno michina.
Pamusoro pekugadzira kwayo, masosi ezvakatipoteredza eMEK anosanganisira kupera simba kubva kujeti uye injini dzinopisa dzemukati, uye zviitiko zvemaindasitiri senge gasification yemarasha.Inowanikwa muhuwandu hwakawanda muutsi hwefodya.MEK inogadzirwa biologically uye yakaonekwa sechigadzirwa che microbial metabolism.Iyo yakawanikwa zvakare muzvirimwa, zvipembenene pheromones, uye mhuka tishu, uye MEK ingangoita chidiki chigadzirwa cheyakajairika mammalian metabolism.Yakagadzikana pasi pemamiriro ezvinhu akajairika asi inogona kugadzira peroxides pakuchengetedza kwenguva refu;izvi zvinogona kunge zvinoputika.
