Methyl Ethyl Ketone (MEK for short) is a colorless, flammable liquid at room temperature with a pungent sweet or minty smell, similar to acetone. Its molecular formula is C₄H₈O, its relative molecular mass is 72.10, and its CAS number is 78-93-3.
Methyl Ethyl Ketone
Methyl Ethyl Ketone, also known as 2-Butanone, is an important organic chemical raw material and excellent solvent with the following wide applications:
- Solvent: 2-Butanone has good solubility in resins, rubbers, etc., and can make coatings and inks have good fluidity, drying properties and glossiness. It is widely used in coatings and printing inks in the fields of furniture, automobiles, ships, etc. It can adjust the viscosity and drying speed of adhesives, enhance the adhesion of adhesives to various materials, and is often used for bonding materials such as wood, leather, plastics, and metals. MEK can be used to clean electronic components and circuit boards, and can effectively remove oil stains, impurities and flux residues without damaging electronic components, ensuring the performance and reliability of electronic equipment.
- Organic synthesis raw materials: MEK can synthesize methyl isobutyl ketone through hydrogenation, condensation and other reactions; it can be used as a raw material for synthetic fragrances to prepare compounds with special aromas; in drug synthesis, MEK can be used as an intermediate to participate in various reactions.
- Oil refining industry: used as a dewaxing agent in the oil refining process, it can reduce the freezing point of lubricating oil and improve its low-temperature fluidity.
- Textile industry: used in the dyeing and printing process of fabrics, it can be used as a solvent and carrier for dyes to help dyes adhere better to fabrics.
- Plastic industry: used as a solvent and plasticizer in the plastic processing process, it can improve the processing performance and flexibility of plastics.
