Methyl ethyl ketone (CAS 78-93-3), also known as MEK or ethyl methyl ketone, is an organic compound with the formula CH3C(O)CH2CH3. This colorless liquid ketone has a sharp, sweet odor reminiscent of acetone.
Chemical Structure of Methyl Ethyl Ketone (MEK)
Methyl ethyl ketone is a four-carbon ketone with a carbonyl group (C=O) located on the second carbon atom of the chain.
- IUPAC name: 2-Butanone
- Common names: Methyl ethyl ketone, MEK
- Chemical formula: C₄H₈O
- Structural formula: CH₃–CO–CH₂–CH₃
The presence of the carbonyl (C=O) functional group gives MEK solvent its polarity, while the short hydrocarbon chain provides good compatibility with non-polar materials. This balanced structure allows methyl ethyl ketone uses across both polar and non-polar systems.
What is MEK methyl ethyl ketone used for?
Solvent:
MEK is a common industrial solvent used in processes involving gums, resins, cellulose acetate, nitrocellulose coatings, and vinyl films. MEK solvent for coatings helps clean and prepare surfaces for painting and is also used in the production of synthetic rubber.
