Dichloromethane (DCM) and methanol are distinct solvents. Although both are highly effective solvents, they differ significantly in polarity, solubility, safety, and applications.
What Is Methylene Chloride?
CAS 75-09-2 Methylene Chloride (dichloromethane or DCM) is a moderately polar chlorinated solvent.
Boiling Point: 39.6°C (evaporates quickly)
Solvency Power: Extremely strong – dissolves most paints, including epoxies, polyurethanes, and acrylics.
What Is methanol?
Methanol (also called methyl alcohol, wood alcohol, and wood spirit, amongst other names) is an organic chemical compound and the simplest aliphatic alcohol.
Dichloromethane (DCM) vs methanol: Properties differences
| Property | Dichloromethane (DCM) | Methanol |
|---|---|---|
| Solvent Type | Chlorinated solvent | Alcohol |
| Molecular Formula | CH₂Cl₂ | CH₃OH |
| Polarity | Moderate | High |
| Density | ~1.33 g/cm³ (heavier than water) | ~0.79 g/cm³ (lighter than water) |
| Water Miscibility | Immiscible | Completely miscible |
| Boiling Point | 39.6°C | 64.7°C |
| Evaporation Rate | Fast | Moderate |
| Extraction Type | Liquid-liquid extraction | Homogeneous (single phase) |
| Solvent Strength | Strong (non-polar to semi-polar) | Strong (polar compounds) |
| Flammability | Non-flammable | Highly flammable |
| Toxicity | Moderate to high | Toxic (poisonous if ingested) |
| Typical Applications | Extraction, paint removal | Synthesis, fuel, cleaning |
Dichloromethane (DCM) vs methanol: Applications differences
DCM: Widely used as a solvent in chromatography (often as the weak solvent, or as a strong solvent in normal phase with hexanes), chemical reactions, and industrial cleaning, according to.
Methanol: Used for high-polarity extraction (e.g., in food technology for phenolic compounds), and in HPLC/GC-MS as a polar solvent.
