Ibikoresho bya Shimi:

Methyl ethyl ketone irashobora kwibasirwa nuburyo butandukanye kubera itsinda ryayo rya karubone hamwe na hydrogène ikora yegeranye nitsinda rya karubone.Ubucucike bubaho iyo ushyutswe na aside hydrochloric cyangwa hydroxide ya sodium kugirango ubyare 3,4-dimethyl-3-hexen-2-imwe cyangwa 3-methyl-3-hepten-5-imwe.Iyo ihuye nizuba ryigihe kirekire, hakorwa Ethane, acide acike nibicuruzwa bya kondegene.Kubyara diacetyl mugihe oxyde na aside nitric.Iyo okiside hamwe ningingo zikomeye za okiside nka acide chromic, aside irike iba.Butanone ihagaze neza kugirango ubushyuhe, kandi ubushyuhe bwumuriro mubushyuhe bwinshi butanga enone cyangwa methyl enone.Iyo ihujwe na alifatique ya alifatique cyangwa aromatique, ketone ifite uburemere buke bwa ketone, ibice bya cyclicale, ketone hamwe na resin.Kurugero, kondegene hamwe na formaldehyde imbere ya hydroxide ya sodium ibanza gutanga 2-methyl-1-butanol-3-imwe, ikurikirwa no kubura umwuma kuri methacrylatone.
Guhindura ibintu bibaho iyo urumuri rw'izuba cyangwa urumuri rwa UV.Kwiyongera hamwe na fenol itanga 2,2-bis (4-hydroxyphenyl) butane.Igisubizo hamwe na alifatique esters imbere yumusemburo wibanze wo kubyara β-diketone.Acylation hamwe na anhydride ya acide imbere ya catisale ya acide kugirango ikore β-diketone.Igisubizo hamwe na hydrogen cyanide kugirango ikore cyanohydrin.Igisubizo hamwe na ammonia kugirango ikore ketopiperidine.Atom α-hydrogen atom ya butanone isimburwa byoroshye na halogene kugirango ikore ketone zitandukanye, nka 3-chloro-2-butanone ikorana na chlorine.Imikoranire na 2,4-dinitrophenylhydrazine itanga umuhondo 2,4-dinitrophenylhydrazone.

Gusaba:

Methyl etyl ketone (2-butanone, Ethyl methyl ketone, methyl acetone) ni umusemburo wa organic wuburozi buke ugereranije, buboneka mubikorwa byinshi.Ikoreshwa mubicuruzwa byubucuruzi nubucuruzi nkigishishwa cyamavuta, amarangi, hamwe nogukora isuku kandi nkigishishwa cya de-shashara.Ikintu gisanzwe cyibiribwa bimwe na bimwe, methyl ethyl ketone irashobora kurekurwa mubidukikije nibirunga numuriro wamashyamba.Bikoreshwa mugukora ifu itagira umwotsi hamwe nubutaka butagira ibara, nkibishishwa, kandi bitwikiriye.Irakoreshwa kandi nka flavoursubstance mu biryo.

MEK ikoreshwa nkigishishwa kuri sisitemu zitandukanye zo gutwikira, urugero, vinyl, ibifata, nitrocellulose, hamwe na acrylic.Ikoreshwa mugukuraho amarangi, lacquer, langi, gusiga amarangi, kashe, kole, kaseti ya magneti, wino yo gucapa, resin, rozine, ibisubizo byogusukura, hamwe na polymerisation.Iboneka mubindi bicuruzwa byabaguzi, kurugero, urugo na sima zishimisha, nibicuruzwa byuzuza ibiti.MEK ikoreshwa mu gusiga amavuta yo gusiga, kwangirika kwibyuma, mugukora uruhu rwubukorikori, impapuro zibonerana hamwe na fayili ya aluminiyumu, kandi nkimiti hagati na catalizike.Numuti ukuramo mugutunganya ibiribwa nibiribwa.MEK irashobora kandi gukoreshwa muguhagarika ibikoresho byo kubaga no kuvura amenyo.
Usibye kuyikora, amasoko y’ibidukikije ya MEK arimo umwuka uva mu ndege na moteri yaka imbere, hamwe n’ibikorwa by’inganda nka gaze y’amakara.Biboneka ku bwinshi mu mwotsi w'itabi.MEK ikorwa mubinyabuzima kandi yamenyekanye nkigicuruzwa cya mikorobe.Yabonetse kandi mu bimera, feromone y’udukoko, no mu nyama z’inyamaswa, kandi MEK birashoboka ko ari umusaruro muto w’inyamabere zisanzwe z’inyamabere.Irahagaze mubihe bisanzwe ariko irashobora gukora peroxide kubikwa igihe kirekire;ibi birashobora guturika.
