Product Profile
1. Chemical Structure and Properties
Molecular Formula: CH₃Cl
Structural Formula: A single chlorine atom bonded to a methyl group.
Appearance: Colorless, flammable gas with a faintly sweet odor.
Boiling Point: –24.2 °C
Density: 0.92 g/L at 25 °C (gas)
Solubility: Slightly soluble in water; miscible with alcohol, ether, and other organic solvents.
Chemical Properties:
Reactive methylating agent.
Stable under normal conditions but decomposes under high temperature forming toxic gases (HCl, phosgene).
2. Industrial Applications
Chemical Intermediate:
Used in the production of silicones (as a precursor to methylchlorosilanes).
Raw material for quaternary ammonium salts and pharmaceuticals.
Refrigerant (historic use): Previously used as refrigerant R-40, but largely replaced due to toxicity and flammability.
Methylating Agent: Widely used in organic synthesis to introduce methyl groups.
Agriculture: Intermediate in pesticide manufacturing.
3. Safety and Toxicology
Health Hazards:
Toxic by inhalation; high exposure may affect central nervous system (dizziness, headache, nausea).
Long-term exposure linked to liver, kidney, and neurological effects.
Flammability: Highly flammable gas; explosive mixtures with air possible.
Protective Measures:
Handle in well-ventilated areas.
Use proper gas detectors, flame-proof equipment, and personal protective equipment (PPE).
4. Environmental and Regulatory Considerations
Environmental Impact:
Volatile organic compound (VOC), contributes to air pollution.
Can persist in the atmosphere but does not significantly deplete ozone.
Regulatory Compliance:
Listed under the US TSCA and EU REACH regulations.
OSHA PEL: 50 ppm (8-hour TWA).
Transport Information:
UN 1063, Hazard Class 2.1 (Flammable Gas).
5. Case Studies and Application Insights
Silicone Manufacturing:
Methyl chloride is the key raw material for producing methylchlorosilanes, which are further processed into silicones used in sealants, lubricants, and medical devices.Organic Synthesis:
Frequently applied in the pharmaceutical industry as a methylating agent to enhance molecular activity.
