Mankhwala:

Methyl ethyl ketone ndi chinthu chorganic compu contraund comlamula c3coch2ch3ch3ch3 ndi kutukwana kwa 72.11. Ndi madzi opanda utoto komanso owoneka bwino ndi fungo lofanana ndi acetone. Mosavuta. Ndizolakwika ndi ethanol, ether, benzene, chloroform ndi mafuta. Sungunulani m'magawo anayi amadzi, koma kusungunuka kumachepa pomwe kutentha kumakulirakulira, ndipo amatha kupanga osakaniza ndi madzi. Kuopsa kochepa, ld50 (rat, pakamwa) 3300mg / kg. Kuyaka, nthunzi imatha kupanga chosakanikirana ndi mpweya. Kukhazikika kwa nthunzi kumakhala ndi mankhwala osokoneza bongo.

Ntchito:

Methyl ethyl ketone (2-atnone, ethyl methyl ketone, methyl acetone) ndi zosintha zoopsa zochepera, zomwe zimapezeka mu mapulogalamu ambiri. Amagwiritsidwa ntchito m'magulu opanga mafakitale komanso malonda ngati zosungunulira zomatira, utoto, ndi zotsukira komanso ngati zosungunulira. Chilengedwe chachilengedwe chazakudya zina, methyl ethyl ketone amatha kumasulidwa mu chilengedwe ndi mapiri ophulika a nkhalango. Amagwiritsidwanso ntchito ngati chakudya.

Mek imagwiritsidwa ntchito ngati zosungunulira zosiyanasiyana zokutira, mwachitsanzo, vinyl, zomata, nitrocellulose, ndi zokutira za acrylic. Amagwiritsidwa ntchito ngati zotuta, mafinya, ma varnasses, opopera zojambula, osindikiza, matepi, masitepe osindikizira, ma roseni, kukonza njira, ndi ma polymerization. Imapezeka m'malo ena ogula, mwachitsanzo, simenti yanyumba ndi yosangalatsa, ndi zinthu zodzaza nkhuni. Mek imagwiritsidwa ntchito kunenepa mafuta, kuchuluka kwa zitsulo, popanga zitsulo zopangidwa, pepala lowoneka bwino ndi zojambulazo zapakatikati komanso zothandizira. Ndiwosungunuka pakukonza zakudya ndi zakudya. Mek ikhoza kugwiritsidwanso ntchito kuphatikiza zida zamano komanso mano.
Kuphatikiza pa kupanga kwake, magwero a mek amaphatikiza kuchokera ku ndege kuchokera ku jet ndi ma injini amkati a njuchi, ndi zochitika zamafakitale monga zopangira malasha. Imapezeka munthawi yayitali mu utsi wa fodya. MEK imapangidwa mwachinsinsi komanso imadziwika kuti ndi mankhwala osokoneza bongo. Zapezekanso muzomera, tizilombo tambiri tambiri, ndi nyama zokhazokha, ndipo msuzi mwina ndi chinthu chaching'ono cha metabolism wamba. Imakhazikika pansi pa zinthu wamba koma imatha kupanga peroxide pa nthawi yayitali; Izi zitha kuphulika.
