Dichloromethane DCM CAS No.75-09-2 for Industrial Applications | Industrial Uses and Properties

Dichloromethane (DCM), also known as methylene chloride (CAS 75-09-2), is a chlorinated organic solvent widely used across industrial sectors due to its excellent solvency, low boiling point, and rapid evaporation characteristics. It plays an important role in pharmaceutical manufacturing, chemical synthesis, coatings, electronics cleaning, metal degreasing, and polymer processing.

CAS No.75-09-2 Dichloromethane is a chlorinated hydrocarbon with the molecular formula CH₂Cl₂. It is a clear, colorless liquid with a mildly sweet odor and exhibits strong solvency toward oils, fats, waxes, resins, polymers, and numerous organic compounds.

Chemical Structure

It has the molecular formula CH₂Cl₂ and consists of one carbon atom bonded to two hydrogen atoms and two chlorine atoms. Its simple chlorinated hydrocarbon structure contributes to its strong solvency, low boiling point, and high volatility, making it widely used in various industrial applications.

Industrial DCM Dichloromethane

Dichloromethane (Methylene Chloride)

Dichloromethane DCM is an indispensable solvent in numerous industrial applications due to its excellent solubility, rapid volatility, and versatile processing characteristics.

1. Solubility Properties

Dichloromethane (DCM) solvent can dissolve many non-polar and moderately polar organic substances commonly used in industrial production, including:

• Acrylic resins, epoxy resins, and polyurethane resins
• Various polymers and polymer additives
• Mineral oils and lubricants
• Paraf and microcrystalline waxes
• Adhesives and coating
• Organic synthesis intermediates

Due to these solubility properties, DCM is widely used in extraction, formulation, paint stripping, and cleaning processes.

2. Low Boiling Point

At atmospheric pressure, the boiling point of DCM is 39.6°C. Its low boiling point allows for efficient removal via evaporation or distillation, offering significant advantages in extraction, post-reaction processing, and cleaning operations.

3. High Vapor Pressure

Methylene chloride has a high vapor pressure at room temperature, allowing it to evaporate rapidly after use. This property is highly beneficial for processes requiring quick solvent removal, such as metal cleaning, electronic component cleaning, and coating removal.

Organic solvent DCM dichloromethane is widely used in pharmaceuticals, chemical processing, coatings, electronics cleaning, metal degreasing, and polymer manufacturing due to its excellent solvency and fast evaporation properties.
