Fa'amatalaga:

Meatotino tau vailaau:

Methyl ethyl ketone ose mea fa'aolaola fa'atasi ma le fua fa'atatau CH3COCH2CH3 ma le mamafa mole e 72.11. O se vai e leai se lanu ma manino ma se manogi e tutusa ma le acetone. Faigofie fe'avea'i. E fa'afefiloi ma le ethanol, eter, benzene, chloroform ma le suauu. Soluble i le 4 vaega o le vai, ae faʻaitiitia le solubility pe a faʻatuputeleina le vevela, ma mafai ona faʻapipiʻi faʻafefiloi azeotropic ma vai. Oona maualalo, LD50 (iole, gutu) 3300mg/kg. mu, ausa e mafai ona fausia paluga paluga ma le ea. O le maualuga maualuga o le ausa o loʻo iai mea faʻamaʻi.

Talosaga:

Methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) ose solvent organic e maualalo le oona, lea e maua i le tele o talosaga. E fa'aaogaina i mea tau alamanuia ma fa'atau oloa e fai ma so'o fa'apipi'i, vali, ma mea fa'amamā ma avea ma so'o solo. O se vaega faanatura o nisi o meaai, methyl ethyl ketone e mafai ona tuʻuina atu i totonu o le siosiomaga e maugamu ma afi o le vaomatua. E faʻaaogaina i le gaosiga o le paʻu e leai se asu ma le lanu synthetic resins, e pei o se solvent, ma le insurface coating. E fa'aaogaina fo'i e fai ma mea fa'aono i mea'ai.

MEK o loʻo faʻaaogaina e fai ma solvent mo faiga faʻapipiʻi eseese, mo se faʻataʻitaʻiga, vinyl, faʻapipiʻi, nitrocellulose, ma faʻapipiʻi acrylic. E faʻaaogaina i mea vali vali, lacquers, varnishes, vali vali, faʻamaufaʻailoga, kelu, lipine maneta, vaitusi lolomi, resins, rosins, vaifofo faamamaina, ma mo polymerization. E maua i isi oloa fa'atau, mo se fa'ata'ita'iga, sima fale ma mea e fiafia i ai, ma oloa fa'atumu fafie. MEK o loʻo faʻaaogaina i le suauʻu lubricating dewaxing, le faʻafefe o metala, i le gaosiga o paʻu gaosia, pepa manino ma le alumini pepa, ma o se vailaʻau vavalo ma faʻamalosi. O se mea e fa'afefeteina ai mea'ai i le gaosiga o mea'ai ma mea'ai. E mafai fo'i ona fa'aogaina le MEK e fa'amama ai masini tipitipi ma nifo.
I le faaopoopo atu i lona gaosiga, o puna o le siosiomaga o le MEK e aofia ai le gase mai le vaalele ma afi afi i totonu, ma galuega tau alamanuia e pei o le fa'asaoina o koale. E maua i se aofaiga tele i le asu tapaa. MEK e gaosia fa'ale-ola ma ua fa'ailoaina ose mea e maua mai i le fa'ato'aga o meaola ninii. Ua maua foi i la'au, pheromones iniseti, ma aano o manu, ma o le MEK atonu o se mea itiiti o le metabolism mamame masani. E mautu i lalo o tulaga masani ae mafai ona fausia peroxyide i luga o le teuina faaumiumi; atonu e papa.
