Chemical Properties:

Methyl ethyl ketone ndi organic pawiri ndi mankhwala formula CH3COCH2CH3 ndi molecular kulemera kwa 72.11. Ndi madzi opanda mtundu komanso owoneka bwino okhala ndi fungo lofanana ndi acetone. Mosavuta kusakhazikika. Zimaphatikizana ndi ethanol, ether, benzene, chloroform ndi mafuta. Kusungunuka mu magawo 4 a madzi, koma kusungunuka kumachepa pamene kutentha kumawonjezeka, ndipo kungapangitse kusakaniza kwa azeotropic ndi madzi. Low kawopsedwe, LD50 (koswe, pakamwa) 3300mg/kg. kuyaka, nthunzi akhoza kupanga kuphulika kusakaniza ndi mpweya. Kuchuluka kwa nthunzi kumakhala ndi mankhwala oletsa ululu.

Ntchito:

Methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) ndi organic zosungunulira wa kawopsedwe otsika, amene amapezeka ntchito zambiri. Amagwiritsidwa ntchito m'mafakitale ndi malonda monga zosungunulira zomatira, utoto, ndi zoyeretsa komanso ngati zosungunulira zosungunulira. Chigawo chachilengedwe cha zakudya zina, methyl ethyl ketone imatha kutulutsidwa m'chilengedwe ndi mapiri ndi moto wa nkhalango. Amagwiritsidwa ntchito popanga ufa wopanda utsi ndi utomoni wopanda utoto, monga zosungunulira, ndi zokutira zamkati. Amagwiritsidwanso ntchito ngati chokometsera m'zakudya.

MEK imagwiritsidwa ntchito ngati chosungunulira pamakina osiyanasiyana okutira, mwachitsanzo, vinyl, zomatira, nitrocellulose, ndi zokutira za acrylic. Amagwiritsidwa ntchito pochotsa utoto, ma lacquers, ma varnish, utoto wopopera, zosindikizira, zomatira, matepi a maginito, inki zosindikizira, ma resin, ma rosin, zotsukira, komanso polima. Amapezeka muzinthu zina zogula, mwachitsanzo, simenti zapakhomo ndi zosangalatsa, ndi zinthu zodzaza matabwa. MEK ntchito dewaxing mafuta mafuta, degreasing zitsulo, kupanga kupanga zikopa, mandala pepala ndi zojambulazo aluminiyamu, ndi monga mankhwala wapakatikati ndi chothandizira. Ndi zosungunulira m'zigawo pokonza zakudya ndi zosakaniza chakudya. MEK itha kugwiritsidwanso ntchito kuletsa zida za opaleshoni ndi zamano.
Kuphatikiza pakupanga kwake, gwero lachilengedwe la MEK limaphatikizapo utsi wa ndege ndi injini zoyatsira mkati, ndi zochitika zamafakitale monga kutulutsa malasha. Amapezeka mu utsi wochuluka wa fodya. MEK imapangidwa mwachilengedwe ndipo yadziwika kuti idapangidwa ndi tizilombo toyambitsa matenda. Zapezekanso muzomera, ma pheromones a tizilombo, ndi minyewa ya nyama, ndipo MEK mwina ndi chinthu chaching'ono cha metabolism yachibadwa ya mammalian. Imakhala yokhazikika pansi pazikhalidwe wamba koma imatha kupanga peroxides pakusungidwa kwanthawi yayitali; izi zitha kukhala zophulika.
