Na Waiwai Kemika:

ʻO ka Methyl ethyl ketone (MEK) he wai waihoʻoluʻu ʻole me kahi ʻala i wehewehe ʻia ma ke ʻano he ʻoi loa, ʻala, peppermint, a i ʻole acetone like.Hiki ke hoʻoheheʻe ʻia i loko o ka wai a hiki i ka 28% ma ke kaumaha a hiki ke hui pū me nā mea hoʻoheheʻe organik ʻē aʻe.ʻO ka palena pahū haʻahaʻa he 1.4% a ʻo ka palena pahū luna he 11.4%.ʻAʻole kūpono paha ka Methyl ethyl ketone me nā oxidizer ikaika, amines, ammonia, inorganic acids, caustics, isocyanates, a me pyridines.Ke hoʻohana ʻia i ka ʻoihana, pono e mālama ʻia ka methyl ethyl ketone me ka makaʻala, no ka mea, he wai ʻaʻa ʻo NIOSH papa lB.

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 ʻē aʻe, no ka laʻana, nā sima hale a me nā leʻaleʻa, 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 ka MEK no ka hoʻomaʻemaʻe ʻana i nā mea hana ʻoki a me nā 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.
