Methyl ethyl ketone (MEK) is a chemical compound with the molecular formula C4H8O. It is a highly volatile, colorless liquid with a sweet odor. MEK is classified as a ketone, specifically a methyl ketone, due to the presence of a carbonyl group attached to a methyl and an ethyl group.
MEK is commonly used as a solvent in various industrial applications. Its high solvency power makes it effective in dissolving a wide range of substances, including resins, adhesives, coatings, and printing inks. It is particularly suitable for coatings due to its ability to evaporate quickly without leaving residue, resulting in a smooth and even finish.
Due to its strong solvent properties, MEK should be handled with caution. Prolonged exposure to MEK vapor or skin contact can cause irritation, and inhalation of its fumes in high concentrations may result in dizziness or headaches. Therefore, adequate ventilation and personal protective equipment, such as gloves and goggles, are recommended when working with this chemical.
Aside from its industrial uses, MEK is also utilized as a denaturant in laboratory and fuel applications. In laboratory settings, it is commonly employed as a solvent for extraction and purification processes. In fuel applications, MEK is added to gasoline or other fuels to deter their consumption as an intoxicant.
Overall, methyl ethyl ketone is a versatile solvent with wide-ranging industrial applications due to its superior solvency power, quick evaporation, and compatibility with various materials.
