Chemical Name: Di-N-Octylamine
Synonyms: Dioctylamine, N,N-Dioctylamine
Chemical Formula: C16H35N
CAS Number: 111-86-4
Typical Use: Organic synthesis, corrosion inhibitors, surfactants, lubricants
Physical State: Oily liquid
Main Dangers: Irritating to skin, eyes, and respiratory tract; potential for harm by inhalation or skin contact
Fire Risks: Can form flammable vapors at higher temperatures; significant hazard in confined spaces
Acute Exposure: Causes redness, pain, or even chemical burns with direct exposure
Long-Term Exposure: Extended skin contact sometimes causes dermatitis or allergic reactions; prolonged inhalation may impact lung function
Purity: Typically over 98%
Main Component: Di-N-Octylamine
Impurities: Trace levels of secondary and tertiary amines, unreacted alcohols
For Inhalation: Move victim to fresh air quickly; monitor for breathing problems; medical attention often becomes necessary with severe reactions
For Skin Contact: Remove contaminated clothing; wash exposed area thoroughly with soap and water; persistent pain or irritation calls for medical review
For Eye Contact: Rinse cautiously with clean water for several minutes; keep eyes open and remove contact lenses if easy; see a doctor if irritation persists
For Ingestion: Seek immediate medical help; do not induce vomiting; rinse mouth with water if conscious
Suitable Extinguishing Methods: Dry chemical, foam, or carbon dioxide work best
Hazards from Combustion: Releases irritating or toxic gases, including nitrogen oxides and carbon monoxide
Precautions: Firefighters need full protective gear and self-contained breathing apparatus, especially in enclosed spaces
Other Concerns: Product floats and spreads fire on water; always watch out for re-ignition
Personal Protection: Don gloves, goggles, and chemical-resistant clothing
Small Spills: Mop up with absorbent material such as vermiculite or sand
Large Spills: Isolate area; keep out unnecessary personnel; use dust mask or respirator if risk of vapors
Environmental Impact: Prevent from entering drains, soil, or water sources
Cleanup: Collect material in suitable, clearly-labeled containers for proper disposal
Safe Handling: Always work in areas with good ventilation; avoid direct contact or breathing fumes; keep containers tightly sealed when not in use
Storage Conditions: Store away from heat, flames, and strong oxidizers; prefer cool, dry, and well-ventilated spaces
Special Hints: Use corrosion-resistant containers; keep away from food and incompatible materials
Ventilation: Use local exhaust or fume hoods for indoor tasks
Respiratory Protection: Wear approved respirators in dusty, misty, or poorly ventilated rooms
Eye and Face Protection: Goggles or face shields essential for splash risk
Skin Protection: Use nitrile or neoprene gloves and lab coats or aprons
Appearance: Colorless to pale yellow oily liquid
Odor: Ammoniacal, sometimes faintly fishy
Melting Point: Solidifies below room temperature but varies
Boiling Point: Above 282°C (539°F)
Density: About 0.8 g/cm³
Solubility: Poorly soluble in water; miscible with organic solvents
Vapor Pressure: Low under normal conditions
Flash Point: Can exceed 130°C (266°F), so routine handling at room temperature carries far less fire risk
Chemical Stability: Remains stable in sealed containers under standard conditions
Hazardous Reactions: Reacts with acids, oxidizing agents, and some metals, releasing heat or hazardous vapors
Decomposition Issues: Burns or decomposes unpredictably at high heat, giving off harmful gases
Acute Effects: Exposure leads to irritation of skin, eyes, and upper respiratory tract; absorption through skin sometimes causes systemic effects
Chronic Effects: Ongoing exposure may damage liver or kidneys; some animal studies link long-term exposure to neurological changes
Sensitization: Allergic skin reactions occasionally develop after repeated handling
Other Safety Notes: No recognized evidence for carcinogenicity in humans, but always err on the side of caution
Environmental Fate: Breaks down slowly in water and soil; significant risk for bioaccumulation in aquatic organisms
Hazard to Wildlife: Toxic to fish and some invertebrates at lower concentrations
Persistence: Not readily biodegradable—responsible disposal always matters for long-term ecosystem health
Preferred Method: Send waste material to licensed hazardous waste facility
Do Not: Pour into drains, sewers, or the environment
Container Care: Keep lids tightly closed and label clearly—residue risk stays long after the last drop
Local Rules: Follow all regional and federal waste management requirements to the letter
Transport Class: Typically assigned as hazardous for road, sea, or air
Packaging: Use chemical-resistant, leak-proof drums or cans
Spill Risks: Label shipments clearly; emergency procedures needed for larger loads or bulk transit
Workplace Safety: U.S. OSHA treats it as hazardous, with rules for exposure controls
Global Status: Present on many national chemical inventories such as TSCA, REACH
Labeling Requirements: Clear hazard communication needed for transport and storage; safety information must be accessible and up-to-date
