Kufunga:

Zvemakemikari zvivakwa:

Methyl EtHyl Ketone ndeye organic compound ine makemikari formula ch3coch2ch3 uye inorema uremu hwe72.11. Iyo isina ruvara uye inojekesa mvura ine chinwiwa chakafanana neacetone. Nyore kuenderana. Izvo zvinokanganisa zvisizvo neEthanol, Ether, Benzene, Chloroform neoiri. Svutugadzike mumativi mana emvura, asi iyo solubility inoderera kana tembiricha ichiwedzera, uye inogona kuumba musanganiswa weAzeotropic nemvura. Yakadzika yepfuma, ld50 (rat, yemuromo) 3300mg / kg. Anopisa, mupfu anogona kuumba musanganiswa unoputika nemhepo. Kuwedzeredza kwepamusoro kweMapor kune anesthetic zvivakwa.

Chikumbiro:

Methyl EtHyl Ketone (2-Butyl, Ethyl methyl ketone, methyl acetone) isimbiso yemhando yehupfu hwakadzika, hunowanikwa mune akawanda mashandisiro. Iyo inoshandiswa muindasitiri uye yekutengesa zvigadzirwa sechigadzika chezvinoshambidza, pendi, uye kuchenesa vamiririri uye seyakagadziriswa solvent. Chinhu chechisikigo chechimwe chikafu, methyl ethyl ketone inogona kuburitswa munharaunda nemapurisa. inoshandiswa mune yakasarudzika yehupfumi hwehupfu uye solvent. Iyo inoshandiswawo seyakavharirwa kwekudya mune chikafu.

Mek inoshandiswa solvent kune akasiyana siyana ekubatanidza masisitimu, semuenzaniso, vinyl, anomisheni, nitrocellulose, uye mahedheni ezvipfuyo. Rinoshandiswa pakupenda rinoburitsa, mapopoma, varvitiki, vapfidze pendi, glues, glues, resins, rosins, rotsins, kuchenesa mhinduro, uye for polmerization. Inowanikwa mune zvimwe zvigadzirwa zvevatengi, semuenzaniso, imba uye mitezo yemumba, uye zvigadzirwa zvinozadza matanda. Mek inoshandiswa mukuremerwa kwemafuta, mushambadzi wesimbi, mukugadzirwa kwemasimbi anodzvinyirira, pepa rejekerere uye aluminium foil, uye semakemikari epamhepo uye anobatsira. Iyo inzvimbo yekubvisa mukugadziriswa kwekugadzirisa kwekudya uye zvekudya zvinoshandiswa. Mek inogona zvakare kushandiswa kudzora kuvhiya uye mazino michina.
Pamusoro pekugadzira kugadzirwa kwayo, zvinyorwa zvematare zveMEK zvinosanganisira kuneta kubva kuJet uye yemukati minjini yeinjini, uye zviitiko zveindasitiri zvakadai sekutarisana nemarasha. Inowanikwa mune yakakura huwandu muutsi hwefodya. Mek inoburitswa biologically uye yakaonekwa sechigadzirwa che microbial metabolism. Iyo yakawanikwawo muzvirimwa, zvipembenene pheromones, uye mhuka dzemhuka, uye mek ingangove chidiki chidiki cheyakajairika mammalian metabolism metabolism metabolism metabolism metabolism. Iyo yakagadzikana pasi pemamiriro ezvinhu akajairwa asi inogona kuumba peroxides pakuchengetedza kwenguva refu; Izvi zvinogona kunge zvichiputika.
