1. Chemical Structure and Properties

• Molecular Formula: CH₂Cl₂

• Structural Formula: ClCH₂CH₂Cl — A volatile halogenated solvent with two chlorine atoms bonded to a methane backbone.

• Physical Properties:

• Appearance: Colorless, volatile liquid

• Boiling Point: 39.6°C

• Density: 1.33 g/cm³ at 20°C

• Solubility: Slightly soluble in water; miscible with most organic solvents

• Chemical Properties:

• Relatively stable under normal conditions but can decompose under high heat or in the presence of strong bases

• Non-flammable but can form toxic gases if burned

• Excellent solvent for fats, oils, waxes, resins, and polymers

  
  

2. Industrial Applications

• Solvent in Chemical Processes: Used in extraction, degreasing, and paint stripping

• Pharmaceutical and Cosmetic Industry: Employed as a solvent for coating and encapsulation

• Electronics: Applied in cleaning and precision metalworking

  
  

3. Safety and Toxicology

• Health Hazards:

• Inhalation: Can cause dizziness, headache, nausea, and central nervous system depression

• Skin/Eye Contact: May cause irritation; prolonged exposure can lead to dermatitis

• Chronic Exposure: Potential liver and kidney effects

• Fire & Explosion: Non-flammable but should avoid open flames due to toxic fumes

• Protective Measures: Use in well-ventilated areas, wear appropriate PPE including gloves, goggles, and respirators

  
  

4. Environmental and Regulatory Considerations

• Environmental Impact: Low persistence in water; avoid discharge into waterways

• Regulatory Compliance:

• Registered under EU REACH and US TSCA

• Transport: UN 1593, Class 6.1 (Toxic), Packing Group III

  
  

5. Case Studies and Application Insights
