Chemical Name: N,N-Diethylethanolamine
Synonyms: DEEA, 2-(Diethylamino)ethanol
Molecular Formula: C6H15NO
CAS Number: 100-37-8
Appearance: Clear, colorless or pale yellow liquid with an ammonia-like odor
Uses: Additive in cement grinding, intermediate in pharmaceuticals and coatings, corrosion inhibitor, gas treatment agent
GHS Classification: Causes skin and serious eye irritation, may be harmful if inhaled
Signal Word: Warning
Hazard Statements: Skin irritation, eye irritation, harmful effects on respiratory tract with prolonged exposure
Pictograms: Corrosive, exclamation mark
Possible Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Component: N,N-Diethylethanolamine
Purity: Generally 98% or higher in industrial samples
Impurities: May contain trace amounts of related amines, water, or manufacturing residues
Inhalation: Remove to fresh air, provide oxygen if breathing is difficult, seek medical help if coughing or irritation develops
Skin Contact: Take off contaminated clothing, wash with plenty of soap and water, consult a doctor for any persistent skin reaction
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses, continue rinsing, get medical advice if irritation persists
Ingestion: Rinse mouth, do not induce vomiting, seek medical attention if feeling unwell
Suitable Extinguishing Media: Dry chemical powder, alcohol-resistant foam, water spray, carbon dioxide
Hazards from Combustion: Vapors may form explosive mixtures with air, combustion can release nitrogen oxides, carbon monoxide, and irritating fumes
Firefighter Protection: Use self-contained breathing apparatus, full protective clothing
Additional Notes: Prevent runoff from fire control into sewers or waterways; containers may rupture under intense heat
Personal Precautions: Avoid breathing vapors, avoid skin contact, ventilate area
Environmental Precautions: Prevent spillage from entering drains, soil, or water bodies
Clean Up Methods: Absorb small spills with inert materials like sand or vermiculite, collect and dispose according to local regulations, wash area with water following removal
Safe Handling: Work in a well-ventilated space, minimize splashing, keep away from open flames and hot surfaces
Storage: Keep tightly closed in a cool, dry, well-ventilated area, segregate from acids and strong oxidizers, use corrosion-resistant containers
Incompatibilities: Avoid contact with strong acids, strong oxidizing agents, some plastics, and aluminum due to risk of corrosion or reaction
Engineering Controls: Good local ventilation, mechanical exhaust to reduce vapor build-up
Respiratory Protection: NIOSH/MSHA approved respirator if exposure limits are exceeded or ventilation is inadequate
Skin Protection: Chemical-resistant gloves such as nitrile or neoprene, lab coat, splash apron
Eye Protection: Safety goggles or face shield
Hygiene Measures: Avoid eating, drinking, or smoking while handling, wash hands thoroughly after use
Physical State: Liquid
Color: Colorless to pale yellow
Odor: Ammonia-like
Boiling Point: Approximately 208°C
Melting Point: -54°C
Flash Point: 92°C (closed cup)
Solubility: Miscible with water, alcohol, and most polar organic solvents
Vapor Pressure: Low at room temperature
Density: About 0.89 g/cm³ at 20°C
Chemical Stability: Tends to remain stable under recommended storage and handling conditions
Conditions to Avoid: Heat, sparks, open flames, direct sunlight
Materials to Avoid: Acids, strong oxidizers, some metals
Decomposition Products: Nitrogen oxides, carbon oxides, toxic vapor formation on burning
Potential Hazard: Thermal decomposition can cause pressure build-up in closed containers
Acute Effects: Causes irritation to eyes, skin, and respiratory tract
Symptoms from Exposure: Burning sensation, redness, coughing, headache, nausea
Chronic Effects: Repeated or prolonged exposure can lead to dermatitis or respiratory irritation
Toxicity Data: Oral LD50 (rat) is several grams per kilogram; significant quantities required for severe poisoning
Aquatic Toxicity: Harmful to aquatic organisms in high concentrations
Persistence and Degradability: Expected to degrade but can temporarily affect water quality
Bioaccumulation Potential: Low, based on chemical structure and water solubility
Other Effects: Large spills pose risk to aquatic habitats due to pH changes and oxygen demand
Waste Treatment Method: Incinerate under controlled conditions or dispose as hazardous chemical waste according to local, regional, or national regulations
Containers: Triple rinse drums and dispose or recycle via licensed processor; avoid reuse for non-chemical materials
Avoid: Discharging to surface water, soil, or public sewer system
Proper Shipping Name: N,N-Diethylethanolamine
Transport Hazards: Not classified as hazardous for most international road and rail shipments
Packaging Requirements: Secure, clearly labeled, leak-proof containers
Cautions: Avoid excessive heat, prevent container breakage during loading and unloading, check regulations before shipping internationally or by air
Agency Listings: Included on major chemical inventories such as TSCA, EINECS
Safety Classification: Workplace exposure limits set by some regulatory bodies; usually requires detailed labeling under Hazard Communication rules
Occupational Restrictions: Protective measures and engineering controls required under workplace health and safety standards
