Na Waiwai Kemika:

Hiki i ka Methyl ethyl ketone ke hoʻololi i nā hopena like ʻole ma muli o kāna pūʻulu carbonyl a me ka hydrogen hana e pili ana i ka hui carbonyl. Hana ʻia ka condensation ke hoʻomehana ʻia me ka waikawa hydrochloric a i ʻole ka sodium hydroxide e hana ai i 3,4-dimethyl-3-hexen-2-one a i ʻole 3-methyl-3-hepten-5-one. Ke ʻike ʻia i ka lā no ka manawa lōʻihi, hana ʻia ka ethane, acetic acid a me nā huahana condensation. E hana i ka diacetyl i ka wā i hoʻoheheʻe ʻia me ka waikawa nitric. Ke hoʻoheheʻe ʻia me nā mea oxidizing ikaika e like me ka chromic acid, hana ʻia ka acetic acid. Paʻa ka Butanone i ka wela, a ʻo ka wehe ʻana i ka wela ma nā mahana kiʻekiʻe e hoʻopuka ai i ka enone a i ʻole methyl enone. Ke hoʻopili ʻia me nā aldehydes aliphatic a i ʻole aromatic, hoʻopuka ʻia nā ketone kiʻekiʻe molecular weight, cyclic compound, ketone condensation a me nā resins. No ka laʻana, ʻo ka condensation me formaldehyde i mua o ka sodium hydroxide e hoʻopuka mua i ka 2-methyl-1-butanol-3-one, a ukali ʻia e ka maloʻo i ka methacrylatone.
Hana ʻia ka resinization ma ka ʻike ʻana i ka lā a i ʻole ke kukui UV. ʻO ka condensation me ka phenol ka 2,2-bis(4-hydroxyphenyl)butane. Hoʻopili me nā esters aliphatic i mua o kahi catalyst kumu e hana i nā β-diketones. Acylation me ka acidic anhydride ma ke alo o ka acidic catalyst e hana i β-diketones. Hoʻopili me ka hydrogen cyanide e hana i cyanohydrin. Hoʻopili me ka ammonia e hana i nā derivatives ketopiperidine. Hoʻololi koke ʻia ka α-hydrogen atom o butanone me nā halogens e hana i nā ketone halogenated like ʻole, e like me 3-chloro-2-butanone ma o ka launa pū ʻana me ka chlorine. ʻO ka pilina me ka 2,4-dinitrophenylhydrazine e hoʻopuka i ka melemele 2,4-dinitrophenylhydrazone.

Noi:

ʻO ka methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) he mea hoʻoheheʻe kūlohelohe o nā meaʻawaʻawa haʻahaʻa, i loaʻa i nā noi he nui. Hoʻohana ʻia ia i nā huahana ʻoihana a me nā mea kūʻai aku ma ke ʻano he mea hoʻoheheʻe no nā adhesives, pena, a me nā mea hoʻomaʻemaʻe a ma ke ʻano he de-waxing solvent. ʻO kahi mea kūlohelohe o kekahi mau meaʻai, hiki ke hoʻokuʻu ʻia ka methyl ethyl ketone i ke kaiapuni e nā lua pele a me nā ahi ahi. Hoʻohana ʻia ia ma ke ʻano he mea ʻono i ka meaʻai.

Hoʻohana ʻia ʻo MEK ma ke ʻano he solvent no nā ʻōnaehana hoʻopili like ʻole, no ka laʻana, vinyl, adhesives, nitrocellulose, a me nā uhi acrylic. Hoʻohana ʻia ia i ka wehe ʻana i ka pena, nā lacquers, nā varnish, nā pena ehu, nā sila, nā glues, nā lipine magnetic, nā inika paʻi, resins, rosins, nā hoʻomaʻemaʻe hoʻomaʻemaʻe, a no ka polymerization. Loaʻa ia i nā huahana mea kūʻai aku, no ka laʻana, nā hale a me nā mea hoʻokipa hoʻokipa, a me nā huahana hoʻopiha lāʻau. Hoʻohana ʻia ʻo MEK i ka ʻaila lubricating dewaxing, ka degreasing o nā metala, i ka hana ʻana i nā ʻili synthetic, ka pepa aniani a me ka alumini alumini, a ma ke ʻano he mea waena a me ka catalyst. He mea hoʻoheheʻe ʻia i ka hana ʻana i nā meaʻai a me nā meaʻai. Hiki ke hoʻohana ʻia ʻo MEK no ka hoʻomaʻemaʻe ʻana i nā mea ʻoki a me nā mea niho.
Ma waho aʻe o kāna hana ʻana, ʻo nā kumu kaiapuni o MEK e loaʻa i ka pauku mai nā jet a me nā ʻenekini hoʻopau i loko, a me nā hana ʻoihana e like me ka gasification o ka lanahu. Loaʻa ia ma ka nui o ka uahi paka. Hana ʻia ʻo MEK ma ke ʻano biologically a ua ʻike ʻia he huahana o ka microbial metabolism. Ua ʻike ʻia i loko o nā mea kanu, nā pheromones insect, a me nā ʻiʻo holoholona, ​​​​a ʻo MEK paha kahi huahana liʻiliʻi o ka metabolism mammalian maʻamau. Paʻa ia ma lalo o nā kūlana maʻamau akā hiki ke hana i nā peroxides ma kahi mālama lōʻihi; he pahū paha kēia.
