Methyl ethyl ketone (CAS 78-93-3), tseem hu ua MEK lossis ethyl methyl ketone, yog cov organic compound nrog cov mis CH3C (O) CH2CH3. Cov kua tsis muaj xim tsis muaj xim ketone muaj qhov ntse, qab zib tsw qab ntawm acetone.
Chemical Structure ntawm Methyl Ethyl Ketone (MEK)
Methyl ethyl ketone yog plaub-carbon ketone nrog cov pa roj carbonyl pawg (C=O) nyob rau ntawm cov pa roj carbon thib ob ntawm cov saw hlau.
- IUPAC lub npe: 2-Butanone
- Cov npe nrov: Methyl ethyl ketone, MEK
- Cov tshuaj formula: C₄H₈O
- Cov qauv tsim qauv: CH₃–CO–CH₂–CH₃
Lub xub ntiag ntawm carbonyl (C=O) pab pawg ua haujlwm ua rau MEK hnyav nws cov polarity, thaum lub luv hydrocarbon saw muab kev sib raug zoo nrog cov khoom tsis yog -polar. Cov qauv sib npaug no tso cai rau methyl ethyl ketone siv thoob plaws hauv cov polar thiab tsis yog -polar systems.
MEK methyl ethyl ketone siv rau dab tsi?
Solvent:
MEK yog ib qho kev lag luam hnyav uas siv rau hauv cov txheej txheem uas muaj cov pos hniav, resins, cellulose acetate, nitrocellulose coatings, thiab vinyl films. MEK hnyav rau coatings pab ntxuav thiab npaj qhov chaw rau tha xim thiab kuj yog siv nyob rau hauv zus tau tej cov roj hmab hluavtaws.
Chemical Intermediate:
Cov tshuaj MEK methyl ethyl ketone yog siv los ua cov tshuaj nruab nrab los tsim lwm cov tshuaj hauv kev lag luam kws tshuaj, nrog rau kev tsim cov resins thiab paraffin wax, txhawb ntau hom kev siv methyl ethyl ketone.
Adhesives:
MEK tau siv dav hauv kev lag luam nplaum ua MEK nplaum hnyav, qhov uas nws ua haujlwm zoo sib txuas cov yas, textiles, thiab hlau ua ke, ua kom muaj zog thiab txhim khu kev qha adhesion hauv kev lag luam.
Ntxuav:
MEK rau kev ntxuav yog feem ntau siv hauv kev lag luam hluav taws xob rau kev tu kom huv si thiab tseem siv rau kev tshem tawm graffiti, tau txais txiaj ntsig los ntawm kev muaj peev xwm ua kom muaj zog ntawm methyl ethyl ketone MEK hnyav.
Kev luam ntawv:
Hauv kev lag luam luam ntawv, methyl ethyl ketone hnyav yog siv los ua ib feem ntawm inks rau flexographic thiab rotogravure luam ntawv, txhawb kev hloov pauv tus cwj mem, ceev kom qhuav, thiab luam ntawv zoo.
