Mankhwala:

Methyl ethyl ketone imatha kutengera zochita zosiyanasiyana chifukwa cha gulu lake la carbonyl komanso hydrogen oyandikana nawo gulu la carbonyl. Condensation occurs when heated with hydrochloric acid or sodium hydroxide to produce 3,4-dimethyl-3-hexen-2-one or 3-methyl-3-hepten-5-one. Mukakhala kuti mukuwala kwa dzuwa kwa nthawi yayitali, Ethane, acetic acid ndi zinthu zophatikiza zimapangidwa. Pangani discotyll mukakhala ndi nitric acid. Mukakhala ndi oxidid ndi othandizira okoma monga acimiki a acid, acetic acid amapangidwa. Tanone ndi wokhotakhota kuti azitentha, ndipo clectage yotentha pabwino kwambiri imatulutsa zodziwika kapena methyl yolowa. Akalumikizidwa ndi algehatic kapena aldelic aldehydes, matope okwera kwambiri olemera, ma clowe5 mankhwala a cyclic, kufupika kwa Ketolone ndi ma resin amapangidwa. Mwachitsanzo, kuvomerezedwa ndi formaldehyde pamaso pa sodium hydroxide woyamba kutulutsa 2-methyl-1-butanol-3-1-1-3
Kubwereka kumachitika pakuwonekera kwa dzuwa kapena kuwala kwa UV. Kugwirizana ndi phenol kumatha 2,2-bis (4-hydrophyllll) andane. Amakumana ndi etsfic esters pamaso pa chothandizira choyambirira kuti apange β-diketones. Acylation ndi acid acidic pamaso pa othandizira acidic kuti apange β-diketones. Amagwira ndi hydrogen cyanja kuti apange cynohydrin. Amachita ndi ammonia kuti apange ketopipelidine. Atomu ya haid-haidrojeni ya butanone imalowa m'malo okakamiza kuti apange kemoni yosiyanasiyana yofuula, monga 3-chloro-2-yanine polumikizana ndi chlorine. Mogwirizana ndi 2,4-divatterolhydrazine amatulutsa chikasu 2,4-dinesolnylhydrazone.

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.
