The solubility of dichloromethane (CAS 75-09-2) in water is approximately 13–20 g/L at 20 °C. It is considered slightly soluble in water but is miscible with most common organic solvents, including ethanol, diethyl ether, and other chlorinated solvents.
Dichloromethane (DCM) Solubility Specification Table
| Water Solubility | 13 – 17.5 g/L (1.3 – 1.75%) | At 20°C to 25°C |
| Water Solubility (Temp Depend) | 25.6 g/L (15°C) / 15.8 g/L (30°C) | Decreases with rising temperature |
| Solubility in Water | ~1 g / 50 mL | ~2% by weight |
| Miscibility | Miscible with Alcohol, Ether, Acetone, Benzene, CCl₄ | Soluble in common organic solvents |
| Water in DCM | ~0.24% | At 20°C |
| Solvent Density | 1.32 – 1.33 g/mL | Denser than water |
Why Solubility Matters in Industrial Applications
Due to its unique solvency, dichloromethane dissolves numerous organic compounds including resins, fats, oils, and polymers, making it primarily used for:
- Liquid-liquid extraction
- Pharmaceutical synthesis
- Organic reaction solvent
- Analytical sample preparation
Is dichloromethane soluble in water?
Methylene chloride is only slightly soluble, with a solubility of about 13–20 g/L at room temperature (20°C).
Summary
CAS 75-09-2 Dichloromethane/Methylene chloride exhibits limited miscibility with water. However, it mixes well with a wide range of organic solvents, making it widely used in chemical synthesis, laboratory extraction, and industrial solvent applications.
