Why is dichloromethane (CAS 75-09-2) used an extraction solvent?

What is Dichloromethane DCM solvent?

CAS 75-09-2 Dichloromethane, DCM is a high-purity, fast-evaporating, and highly versatile solvent used in industrial applications, chemical synthesis, coatings, adhesives, and metal degreasing. With its low boiling point, excellent solvency power, and non-flammability, Methylene Chloride is widely utilized in paint stripping, resin processing, pharmaceutical manufacturing, and laboratory research.

Why is dichloromethane (CAS 75-09-2) used an extraction solvent?

Dichloromethane (DCM), also known as methylene chloride, is an excellent solvent for extraction processes due to its unique properties. It is a polar aprotic solvent, meaning it has a significant dipole moment, but no hydrogen atoms to participate in hydrogen bonding. This enables

DCM (CAS 75-09-2) to dissolve a wide range of polar and nonpolar compounds, making it highly versatile in extraction processes.

Furthermore, DCM has a low boiling point of 39.6°C and is immiscible with water. This facilitates the separation of the extracted compounds from the solvent through evaporation or using a separatory funnel. The low boiling point also reduces the risk of the extracted compounds undergoing thermal degradation. These properties make dichloromethane an excellent choice for many extraction processes in chemistry and biochemistry.
