Name: Dodecane
Chemical Formula: C12H26
CAS Number: 112-40-3
Appearance: Colorless, clear liquid
Odor: Slight, typically similar to paraffin
Common Uses: Lab solvent, fuel research, organic synthesis
Boiling Point: Roughly 216°C
Flammability: High; vapors can catch fire easily
Health Hazards: Breathing vapors may bother nose, throat, and lungs
Target Organs: Respiratory system, skin, eyes
Environmental Impact: Harmful for aquatic life if released in quantity
Routes of Exposure: Inhalation, skin contact, eye contact, accidental swallowing
Acute Effects: Dizziness, headache, nausea possible after heavy exposure
Chronic Effects: Frequent, prolonged contact might dry out or crack skin
Substance: Dodecane
Purity: Above 95 percent in most laboratory or industrial grades
Impurities: Trace other hydrocarbons may be present, but usually at very low levels
Other Notables: No significant additives or stabilizers in standard samples
Inhalation: Move out to fresh air, loosen tight clothing; get medical advice if symptoms stick around
Skin Contact: Wash off with soap and plenty of water; remove any soaked clothing
Eye Contact: Rinse cautiously with water for several minutes; remove contacts if easy
Ingestion: Rinse mouth, do not induce vomiting, get medical attention
Signs of Exposure: Irritation, redness, headache, dizziness, nausea
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray
Unsuitable Extinguishing Media: Direct water jets may spread burning liquid
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, sometimes smaller hydrocarbons
Special Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Fire Hazards: Vapors heavier than air, may travel and ignite far from source
Personal Protection: Ventilate affected area, keep people away, avoid sparks or flames
Spill Response: Absorb with inert material such as sand or earth, gather up for safe disposal in sealed container
Clean-up: Wash remaining area with water and detergent if permitted
Environmental Precautions: Prevent entry into drains, water ways, or soil; use barriers if needed
Handling Tips: Work in ventilated area, keep away from heat and open flames, avoid breathing vapors
Personal Hygiene: Wash hands thoroughly after handling, do not eat, drink, smoke when using
Storage Conditions: Store in closed, labeled containers in cool, dry, well-ventilated spot away from incompatible substances
Separation: Keep apart from oxidizing agents
Engineering Controls: Use local exhaust ventilation or general room ventilation
Personal Protective Equipment: Safety goggles or splash-proof glasses, gloves resistant to hydrocarbons, lab coat or apron
Respiratory Protection: In poorly ventilated areas, use fume hood or wear a suitable respirator
General Precautions: Remove contaminated clothing, keep workstation tidy to reduce risk
State: Liquid at room temperature
Color: Colorless
Solubility: Insoluble in water, mixes with many organic solvents
Vapor Pressure: Low at room temperature
Density: Just under 0.75 g/cm³
Flash Point: About 74°C
Auto-ignition Temperature: Near 204°C
Chemical Stability: Stable in normal storage and handling
Reactive Hazards: Can react strongly with powerful oxidizing substances
Breakdown Products: Decomposes to carbon monoxide and carbon dioxide in severe fire
Acute Toxicity: Low—it doesn’t absorb well through skin, breath, or gut, but large doses cause problems
Irritation: May cause eye and skin irritation
Long-Term Effects: Not classed as a carcinogen, but chronic overexposure dries skin, may worsen the effects of other chemicals
Inhalation: Large exposures could depress the central nervous system
Aquatic Effects: Toxic to aquatic organisms in bulk; long-term harm builds up if it enters streams or lakes
Mobility: Spreads quickly on water surfaces, can penetrate soil slowly
Persistence: Tends to resist natural breakdown, lingers in the environment
Bioaccumulation: Moderate; can build up in fish and animals over time
Other Hazards: A little dodecane spills go a long way in rivers or wetlands
Residue Disposal: Treat dodecane and soaked materials as hazardous; incinerate or send to approved chemical disposal
Container Handling: Drain thoroughly, triple rinse before recycling or disposal
Environmental Safeguards: Never dump in sewer or ordinary trash, avoid spills on ground
UN Number: UN 2330
Shipping Name: Dodecane
Hazard Class: 3 (flammable liquid)
Packing Group: III
Advice: Ship in tightly closed containers, keep upright, label clearly
Workplace Exposure: Limits may be set for hydrocarbons, check local work safety regulations
Classification: Flammable liquid under chemical law, subject to registration and handling controls in many places
Community Right-to-Know: Many places require notification if you store more than small amounts
Other Legal Restrictions: Disposal, handling, and reporting rules vary by state and country
