Chemical Properties:

Methyl ethyl ketone is an organic compound ine kemikari formula CH3COCH2CH3 uye molecular weight ye 72.11. Imvura isina ruvara uye yakajeka ine kunhuhwirira kwakafanana neacetone. Zviri nyore kushanduka. Inosanganiswa ne ethanol, ether, benzene, chloroform uye mafuta. Soluble muzvikamu zvina zvemvura, asi solubility inodzikira kana tembiricha yawedzera, uye inogona kugadzira azeotropic musanganiswa nemvura. Low toxicity, LD50 (gonzo, nemuromo) 3300mg/kg. chinopisa, mhute inogona kugadzira musanganiswa unoputika nemhepo. Kuwanda kwemhute kune anesthetic properties.

Application:

Methyl ethyl ketone (2-butanone, ethyl methyl ketone, methyl acetone) is organic solvent yeine low low toxicity, inowanikwa mumashandisirwo mazhinji. Inoshandiswa muzvigadzirwa zvemaindasitiri uye zvekutengesa sechinhu chinonyungudutsa chekunamira, pendi, uye maajenti ekuchenesa uye se de-waxing solvent. Chinhu chechisikigo chezvimwe zvikafu, methyl ethyl ketone inogona kuburitswa mumhepo nemakomo anoputika uye moto wesango. Inoshandiswa mukugadzira hupfu husina hutsi uye isina mavara ekugadzira resins, sechinhu chinonyungudutsa, uye insurface coating. Inoshandiswawo sechinhu chinonhuwira muchikafu.

MEK inoshandiswa sechinhu chinonyungudutsa kune akasiyana masisitimu ekupfekedza, semuenzaniso, vinyl, zvinonamira, nitrocellulose, uye acrylic coatings. Inoshandiswa mukubvisa pendi, lacquers, varnishes, pfapfaidzo pendi, sealers, glues, magineti matepi, kudhinda ingi, resin, rosins, kuchenesa mhinduro, uye polymerization. Inowanikwa mune zvimwe zvigadzirwa zvevatengi, semuenzaniso, simiti yemumba uye yekuzvivaraidza, uye zvigadzirwa zvekuzadza huni. MEK inoshandiswa mukudonhedza mafuta ekuzora, kupera kwesimbi, mukugadzirwa kwematehwe ekugadzira, mapepa akajeka uye aluminium foil, uye sekemikari yepakati uye inokonzeresa. Iyo inonyungudutsa yekubvisa mukugadziriswa kwechikafu uye zvigadzirwa zvekudya. MEK inogona zvakare kushandiswa kuchenesa yekuvhiya uye yemeno michina.
Pamusoro pekugadzira kwayo, masosi ezvakatipoteredza eMEK anosanganisira kupera simba kubva kujeti uye injini dzinopisa dzemukati, uye zviitiko zvemaindasitiri senge gasification yemarasha. Inowanikwa muhuwandu hwakawanda muutsi hwefodya. MEK inogadzirwa biologically uye yakaonekwa sechigadzirwa che microbial metabolism. Iyo yakawanikwa zvakare muzvirimwa, zvipembenene pheromones, uye mhuka tishu, uye MEK ingangoita chidiki chigadzirwa cheyakajairika mammalian metabolism. Yakagadzikana pasi pemamiriro ezvinhu akajairika asi inogona kugadzira peroxides pakuchengetedza kwenguva refu; izvi zvinogona kunge zvinoputika.
