MEK (Methyl Ethyl Ketone) yog dab tsi?
Methyl ethyl ketone (cas tsis muaj 78 93 3) , tseem hu ua 2-Butanone los yog MEK, yog ib qho tseem ceeb organic chemical raw khoom siv dav hauv txheej, inks, nplaum, tshuaj ntxuav, thiab lwm yam.
Methyl Ethyl Ketone (MEK) Cov Khoom
Methyl Ethyl Ketone (MEK) muaj cov qauv molecular CH₃COCH₂CH₃ thiab molecular hnyav ntawm 72.11. Cov tshuaj no tshwm sim raws li cov xim tsis muaj xim, pob tshab kua nrog cov ntxhiab tsw zoo ib yam li acetone. Nws yog volatile heev thiab miscible nrog ethanol, diethyl ether, benzene, chloroform, thiab roj. Tshwj xeeb tshaj yog, methyl ethyl ketone pom muaj toxicity tsawg ntawm cov concentrations tsawg, tab sis nws cov vapors ua tshuaj loog ntawm qhov siab. Tsis tas li ntawd, nws yog cov nplaim taws heev, thiab nws cov vapors tuaj yeem tsim cov khoom tawg nrog cua. Yog li ntawd, yuav tsum tau ceev faj heev thaum tuav thiab siv.
mek methyl ethyl ketone siv
Hauv kev lag luam, 2-butanone feem ntau yog siv los ua cov kuab tshuaj. Cov ntawv thov muaj xws li dewaxing lubricants, txheej tsim, dissolving ntau yam resins, thiab ua ib co-boiling distillation tus neeg sawv cev nyob rau hauv lub extraction thiab refining ntawm zaub roj. Nws qhov zoo yog nyob rau hauv muaj zog solubility thiab qis volatility piv rau acetone, positioning nws li nruab nrab -boiling point ketone hnyav.
Methyl ethyl ketone (MEK) kuj tseem ua haujlwm nruab nrab hauv kev tsim tshuaj, dyes, detergents, fragrances, antioxidants, thiab qee yam catalysts. Nws yog siv los ua ke los tiv thaiv- cov tshuaj tua kab mob xws li methyl ethyl ketone oxime, polymerization catalysts xws li methyl ethyl ketone peroxide, thiab etching inhibitors xws li methylpenta-al. Hauv kev lag luam hluav taws xob, methyl ethyl ketone kuj tseem siv los ua tus tsim tawm tom qab photolithography hauv kev sib xyaw ua ke.
Methyl Ethyl Ketone Cia
Methyl ethyl ketone cov kuab tshuaj yuav tsum tau khaws cia rau hauv qhov chaw txias, zoo -ventilated warehouse, deb ntawm qhov hluav taws kub thiab cua sov.
Cov thawv ntim khoom yuav tsum nyob twj ywm. Tsis tas li ntawd, nws yuav tsum tau muab cais los ntawm oxidizers, txo cov neeg ua haujlwm, alkalis, thiab cov khoom zoo sib xws los tiv thaiv kev sib xyaw.
Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv hluav taws xob tsim nyog thiab cov khoom siv hluav taws xob xau thaum muaj xwm ceev kom muaj kev nyab xeeb.
Vim li cas thiaj xaiv Gneebio ua koj tus neeg muag khoom?
Raws li ib tugTom ntej: methyl ethyl ketone (CAS 78-93-3)Chaw tsim tshuaj paus, Gneebio tsom rau cov khoom sib xws, kev siv tau zoo, thiab kev ntseeg siab ntawm cov khoom siv ntau. Lub tuam txhab ua haujlwm raws li kev tswj hwm nruj kom paub meej tiasmethyl ethyl ketone (MEK) ua tau raws li qhov yuav tsum tau muaj ntawm loj - nplai thiab qhov chaw tsim khoom tas mus li.
Qhov tseem ceeb ntawm kev tsim khoom thiab khoom siv zog muaj xws li:
- Tswj purity qib tsim nyog rau kev lag luam thiab khoom siv
- ruaj khov batch-rau-batch zoo rau ntev- kev yuav khoom
- Muaj peev xwm muab tau los txhawb kev cog lus thiab chaw xaj khoom
- Export -npaj ntim thiab cov ntaub ntawv (COA, SDS, thiab lwm yam)
