Methyl Chloride vs. Methylene Chloride: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on January 29, 2024
Methyl chloride (CH₃Cl) is a chlorinated methane, used as a refrigerant; methylene chloride (CH₂Cl₂) is a solvent with two chlorine atoms.
Key Differences
Methyl chloride, also known as chloromethane, is a simple alkyl halide with one chlorine atom attached to a methane molecule. Methylene chloride, or dichloromethane, has two chlorine atoms attached to a methane molecule, making it denser and more volatile.
Methyl chloride is primarily used in the production of silicones and as a refrigerant. Methylene chloride is widely used as an effective solvent in paint removers, degreasers, and in pharmaceuticals.
Methyl chloride is a colorless, flammable gas under standard conditions, with a slightly sweet odor. Methylene chloride is a colorless, non-flammable liquid with a sweet, chloroform-like odor.
Exposure to methyl chloride can affect the central nervous system, while methylene chloride is known to be a potential carcinogen and poses greater health risks due to its toxicity.
Methyl chloride is regulated due to its impact on the ozone layer and as a greenhouse gas. Methylene chloride is heavily regulated in many countries due to its carcinogenic properties and environmental impact.
