Chemical Name: Dipropylamine
Chemical Formula: C6H15N
Common Uses: Dipropylamine usually serves as an intermediate in organic synthesis, dye manufacturing, and as a building block in agrochemicals.
Appearance: Colorless liquid
Odor: Strong, ammonia-like
Boiling Point: About 110°C
Solubility: Moderately soluble in water, mixes well with alcohol and other organic solvents.
Main Risks: Flammable liquid, can produce toxic fumes when burned, strong irritant to eyes, skin, and respiratory system
Health Hazards: Causes moderate to severe eye and skin irritation, prolonged exposure may lead to chemical burns or dermatitis, inhalation can result in nausea, dizziness, headaches, and potentially central nervous system effects.
Environmental Risks: Can be harmful in aquatic environments if spills go unchecked, not easily biodegradable.
Route of Entry: Inhalation, skin and eye contact, ingestion.
Signal Word: Warning or Danger depending on concentration and country-specific guidelines.
Main Ingredient: Dipropylamine (CAS Number: 142-84-7) often present in high purity.
Impurities: Trace amines and water may be present depending on storage and manufacturing.
Formulation: Not typically part of a mixture, but always check for stabilizers or dilution agents as these can alter handling protocols.
Eye Contact: Rinse with plenty of clean water for at least 15 minutes, hold eyelids open, seek medical attention as soon as possible.
Skin Contact: Wash skin thoroughly with soap and water, remove contaminated clothing or shoes, get medical help if irritation persists.
Inhalation: Move into fresh air, keep at rest, seek medical advice if symptoms like coughing, chest tightness, or dizziness develop.
Ingestion: Do not induce vomiting, rinse mouth thoroughly, seek immediate medical attention.
Emergency Notes: Remind first responders to wear proper personal protective equipment when treating contaminated personnel.
Suitable Extinguishing Media: Use foam, dry chemical powder, or carbon dioxide extinguishers.
Hazardous Combustion Products: Nitrogen oxides, carbon monoxide, and unidentified organic compounds may result when burning.
Special Hazards: Vapors form explosive mixtures with air, pools or spills increase risk of fire; heat exposure may cause containers to rupture.
Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus.
Other Precautions: Water spray may help keep containers cool but can also spread contamination.
Personal Precautions: Evacuate unnecessary personnel, ventilate the area well, avoid breathing fumes or coming in direct contact with the chemical.
Containment: Use non-sparking tools and absorbent materials to contain and prevent spread.
Environmental Precautions: Prevent entry into drains, surface or ground water; notify local authorities if large quantities escape.
Cleanup: Collect absorbent, dispose of in accordance with local regulations, wash down residues with water and detergent.
Decontamination: Avoid high-pressure water streams, as these can lead to further spreading.
Handling: Use chemical-resistant gloves and goggles, make sure workspaces have good mechanical ventilation or fume hoods.
Storage Conditions: Store in tightly sealed containers, out of direct light and away from heat, sources of ignition, and oxidizers.
Incompatible Materials: Acids, oxidizing agents, and certain plastics can react dangerously with dipropylamine.
Advice: Keep emergency eyewash stations and showers nearby; avoid eating, drinking, or smoking around this chemical.
Spill Contingencies: Prepare for leaks or spills by setting up containment barriers during long storage.
Exposure Limits: No universally established occupational limits, but always work with levels as low as possible due to irritant properties.
Engineering Controls: Maintain local exhaust, use closed systems or splash guards where splashing can occur.
PPE: Wear protective gloves, safety goggles, long-sleeve lab coats; for high vapor concentrations, use an organic vapor respirator.
Hygiene Measures: Wash hands before breaks and at the end of work, avoid skin contact, change contaminated garments as soon as feasible.
Monitoring: Personal or area air monitoring can be useful for keeping exposure in check, especially during bulk handling or spills.
Physical State: Liquid at room temperature
Color: Clear to slightly yellow
Odor: Ammonia-like, sharp
pH: Basic in solution
Boiling Point: About 110°C
Melting Point: -50°C
Flash Point: Below 27°C
Vapor Pressure: Moderate at room temperature
Density: About 0.74 g/cm³
Solubility: Partially soluble in water, high solubility in many organics
Reactivity: Reacts strongly with acids and oxidizers.
Chemical Stability: Stable under normal conditions with proper storage.
Incompatible Materials: Strong acids and oxidizers, acylating and alkylating agents, halogens.
Decomposition Products: Toxic gases including nitrogen oxides and carbon monoxide may form on heating.
Polymerization: Not expected to undergo hazardous polymerization.
Other Risks: Prolonged heating or contact with reactive substances can increase fire or explosion risk.
Acute Effects: Short-term exposure leads to moderate-to-severe irritation of eyes, skin, and respiratory tract, can cause stomach upset if swallowed.
Chronic Effects: Repeated contact may result in dermatitis or aggravate respiratory and skin conditions.
Routes of Exposure: Eyes, skin, inhalation, ingestion.
Known Symptoms: Burning, stinging, coughing, dizziness, headache.
Sensitization: Not frequently reported, but individual allergies or sensitivities may occur.
Cancer Risk: Not classified as human carcinogen as of most recent research.
Aquatic Toxicity: Toxic to aquatic life at higher concentrations, persistent with slow biodegradation.
Bioaccumulation: Expected to have moderate potential based on chemical structure.
Mobility: Liquid form and water solubility mean spillages can travel without proper containment.
Long-Term Impact: Can upset aquatic ecosystems if disposal and runoff controls are not managed.
Soil Impact: May affect soil microbiota and reduce groundwater quality when repeatedly spilled or improperly disposed.
Disposal Methods: Dispose at approved hazardous waste collection sites, dilute only with protocols established by local legislation.
Do Not: Pour down the drain, onto the ground, nor in regular trash bins.
Container Management: Rinse emptied containers thoroughly before recycling or disposal, puncture to prevent reuse if permitted.
Legal Duties: Follow government and municipal guidelines for disposal of toxic organics, keep thorough disposal records for regulatory compliance.
Shipping Name: Dipropylamine
Hazard Class: Flammable Liquid
Packing Group: II or III depending on volume and packaging
Labeling Requirements: Flammable, Harmful/Irritant labels visible and in durable form.
Special Transport Notes: Protect shipments from heat, secure upright to prevent leaks, carry spill kits and emergency plans especially in bulk loads
Chemical Inventories: Registered in several international chemical inventories such as TSCA (US), EINECS (EU), DSL (Canada).
Workplace Guidelines: Subject to worker health and chemical safety laws, employers must ensure training and access to safety gear.
Environmental Release Reporting: Certain jurisdictions require reporting of accidental releases over designated thresholds.
Other Requirements: Safety data sheets must be maintained and readily available; transport follows international regulations for hazardous chemicals, such as ADR and IMDG codes.
