Chemical Name: Triethylamine
Chemical Formula: C6H15N
Synonyms: TEA, N,N-Diethylethanamine
Appearance: Colorless liquid, strong ammonia-like odor
Uses: Commonly used as a catalyst, corrosion inhibitor, and intermediate in chemical manufacturing, especially for pharmaceuticals, rubber, and resins.
Acute Toxicity: Inhalation or skin contact leads to irritation and chemical burns; high vapor concentrations cause respiratory distress and headaches; may affect central nervous system.
Fire and Explosion: Extremely flammable liquid and vapor; forms explosive mixtures with air.
Chemical Reactivity: Reacts with acids, oxidizers, halogens; produces hazardous gases.
Environmental Risk: Hazardous to aquatic environments at high concentrations; spills pose local waterway risk.
Long-term Exposure: Prolonged exposure could cause liver or kidney injury with repeated contact, and respiratory tract damage from repeated inhalation.
Main Component: Triethylamine (typically over 99%)
Impurities Present: Trace amines, water, and residual solvents can appear in trace quantities depending on production technique.
Inhalation: Remove person quickly to fresh air, keep warm and calm, seek emergency medical help for breathing trouble.
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water for at least 15 minutes; persistent irritation or burns need medical attention.
Eye Contact: Immediately flush with plenty of water for at least 15 minutes; medical evaluation required for pain, redness, or vision problems.
Ingestion: Rinse mouth but avoid giving anything by mouth to an unconscious individual; hospital treatment suggested if swallowed.
Suitable Extinguishing Media: Use dry chemical powder, CO2, or alcohol-resistant foam; water spray can help cool nearby containers.
Protective Equipment: Wear self-contained breathing apparatus, full protective suit.
Specific Hazards: Combustion yields toxic fumes of nitrogen oxides and carbon monoxide.
Fire Response: Clear area of unnecessary personnel, evacuate downwind; cool containers with water to prevent explosion from heat.
Personal Protection: Don chemical resistant gloves, safety goggles, and respiratory protection.
Containment: Restrict spill to smallest possible area, ventilate location, remove ignition sources at once; use non-sparking tools.
Cleanup: Absorb with inert material like vermiculite or sand; collect in closed and labeled containers for disposal.
Environmental Response: Prevent release to drains, soil, or surface water; notify authorities if large spill threatens natural waterways.
Decontamination: Wash area thoroughly with soap and water after spill cleanup.
Storage Conditions: Store in tightly sealed, clearly labeled containers, preferably in a cool, dry, well-ventilated area; keep away from heat, open flame, and incompatible chemicals.
Handling Advice: Work with chemical fume hood or local exhaust; minimize vapor exposure; avoid personal contact at all points—use barriers and safety plans.
Segregation: Isolate from acids, oxidizing agents, halogens, and direct sunlight to decrease risk of hazardous reactions.
Container Storage: Prefer metal or high-grade plastic packaging, checked often for leaks or swelling.
Exposure Limits: OSHA and ACGIH list threshold limit values—set low due to respiratory tract irritation hazard at relatively low ppm.
Engineering Controls: Required local exhaust ventilation, preferably full chemical fume hoods in workplace and storage areas.
Personal Protective Equipment: Chemical safety goggles, impervious gloves, long-sleeved lab wear, if airborne levels exceed limits then a NIOSH-approved respirator becomes essential.
Work Practices: Wash exposed skin after handling, avoid eating, drinking, or smoking near chemical.
Boiling Point: About 89 °C
Melting Point: About -115 °C
Flash Point: -7 °C (closed cup)
Density: Roughly 0.73 g/cm3
Vapor Pressure: Moderate at room temperature
Solubility: Miscible with alcohols and ethers, moderate water solubility
Odor Threshold: Intense, recognizable at low concentrations due to strong ammonia note
Chemical Stability: Stable at room temperature if stored properly away from heat and light.
Incompatible Materials: Vigorous reaction with acids, oxidizers, certain plastics, and acid chlorides.
Hazardous Decomposition: Burns to produce carbon monoxide, carbon dioxide, and nitrogen oxides.
Conditions to Avoid: Exposure to air, ignition sources, and elevated temperatures increases dangers.
Routes of Exposure: Inhalation, skin absorption, ingestion, eye contact—all routes present significant exposure risk.
Acute Effects: Irritation to eyes, skin, and respiratory pathways; headaches, dizziness, and nausea with high vapor exposure.
Chronic Effects: Potential for liver and kidney stress, especially with repeated or high-level exposure.
Sensitization: Some users may develop skin or respiratory sensitization after repeated use.
Cancer Risk: Current long-term animal and human studies do not link this compound to significant increases in cancer risk.
Aquatic Toxicity: Can be harmful to aquatic organisms at high concentrations; risk of fish or invertebrate mortality if spilled into waterways.
Persistence: Moderately biodegradable, but large-scale spills overwhelm local biological cleanup capacity.
Bioaccumulation: Low risk—doesn’t strongly accumulate in aquatic life.
Sewage Impact: Smaller amounts usually broken down by biological treatment, higher concentrations could upset wastewater plant organisms.
Waste Handling: Never dump down drains or sewers; collect and send to hazardous chemical disposal facilities that handle organic amines.
Container Disposal: Rinse empty drums, puncture to prevent reuse, and follow local requirements for hazardous packaging.
Incineration: Suitable for specialized high-temperature incinerators equipped with scrubbers for nitrogen oxides and other byproducts.
Hazard Class: Classified as flammable liquid; strict guidelines for transport by land, air, or water.
Proper Shipping Name: Triethylamine
Packing Group: Often falls under high-priority urgency due to low flash point and toxicity, requiring special labels and leakproof packaging.
Transport Precautions: Secure containers upright, prevent tipping and leakage, insulate from heat or spark sources during transport.
Incident Response: Emergency responders expect distinct hazard signage.
Occupational Limits: Regulatory bodies set occupational exposure limits referencing eye, skin, and respiratory system risk.
Labeling: Laws require hazard pictograms, signal word, and hazard statements on all containers.
Environmental Controls: Wastewater discharge must stay under strict regional thresholds; heavy penalties come with environmental release.
Worker Training: Mandated for anyone in direct contact, reflecting the importance of safe handling and emergency response readiness.
Recordkeeping: Facilities log all volume movements, storage, and disposal activities for regulatory review.
