Chemical Name: 2-Octene
Synonyms: Oct-2-ene, n-octene-2
CAS Number: 111-67-1
Recommended Use: Chemical intermediate, solvent, raw material for organic synthesis
Supplier/Manufacturer: Contact local distributor or manufacturer for supplier identity
Emergency Contact: Refer to national poison control center or emergency hotlines
GHS Classification: Flammable Liquids (Category 3), Skin Irritation (Category 2), Eye Irritation (Category 2A), Aspiration Hazard (Category 1)
Label Elements: Warning, exclamation mark, flame pictogram
Hazard Statements: Flammable liquid and vapor, causes skin irritation, may cause eye irritation, may be fatal if swallowed and enters airways
Precautionary Statements: Keep away from heat, sparks, open flames, and hot surfaces; No smoking; Wear protective gloves and eye protection; If on skin: wash with soap and water; If inhaled: move to fresh air; If in eyes: rinse cautiously with water
Chemical Name: 2-Octene
Chemical Formula: C8H16
CAS Number: 111-67-1
Concentration: >98%
Impurities: Mixtures may include trace isomeric octenes and related hydrocarbons
Inhalation: Move person to fresh air; offer artificial respiration if required; seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, rinse affected skin under running water for several minutes, seek medical care if irritation develops
Eye Contact: Rinse eyes gently with water for several minutes, remove contact lenses if present and easy to do, continue rinsing and seek medical care
Ingestion: Do not induce vomiting, rinse mouth with water, seek immediate medical attention, and provide the safety data sheet to healthcare providers
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide, water spray
Special Hazards: Vapors can form explosive mixtures with air; combustion produces carbon monoxide, carbon dioxide, and potentially irritating fumes
Advice for Firefighters: Use self-contained breathing apparatus and full protective gear
Specific Methods: Cool containers exposed to flame with water spray, avoid spreading spill with water run-off, evacuate area if risk of explosion
Personal Precautions: Evacuate unnecessary personnel, ventilate area, eliminate all ignition sources, avoid inhalation or skin contact
Environmental Precautions: Prevent spillage from entering drains or water sources; notify authorities if significant environmental contamination occurs
Methods for Cleanup: Contain spill with inert material such as sand, absorb and place in chemical waste containers, use non-sparking tools, ventilate the area
Handling: Avoid direct contact with skin, eyes, or clothing; ground and bond containers during transfer; use explosion-proof electrical equipment; avoid breathing vapor
Storage: Store in a well-ventilated, flame-proof facility; keep containers tightly closed; segregate from strong oxidizers, acids, and ignition sources; maintain storage temperature below 30°C
Occupational Exposure Limits: No specific limits established; observe general hydrocarbon exposure guidelines
Engineering Controls: Use local exhaust ventilation, explosion-proof equipment, ensure eyewash and safety shower are available
Personal Protective Equipment: Nitrile gloves, chemical splash goggles, flame-resistant lab coat, respiratory protection if vapor exceeds permissible exposure level; avoid open flames or sparks
Appearance: Colorless liquid
Odor: Mild hydrocarbon odor
Molecular Weight: 112.21 g/mol
Boiling Point: 123-124°C
Melting Point: -80°C
Density: 0.72-0.74 g/cm³ at 20°C
Vapor Pressure: 17 mmHg at 25°C
Flash Point: 22°C (closed cup)
Solubility: Insoluble in water, soluble in most organic solvents
Viscosity: Low
Partition Coefficient (log Kow): 4.2
Auto-Ignition Temperature: 215°C
Chemical Stability: Stable under recommended storage conditions
Conditions to Avoid: Heat, flames, sparks, electrostatic discharge, strong sunlight
Incompatible Materials: Strong oxidizing agents, acids, halogens
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, potentially hazardous hydrocarbons
Polymerization: Will not occur under normal handling and storage conditions
Acute Toxicity: Low acute oral and dermal toxicity for short-term exposure; animal studies suggest LD50 (rat, oral) >2000 mg/kg
Irritation: May cause mild to moderate skin and eye irritation
Inhalation: Exposure to high concentrations may cause dizziness, headache, or respiratory irritation
Sensitization: No data supporting sensitization potential
Chronic Effects: Routine occupational exposure has not demonstrated systematic toxicity, but aspiration hazard remains significant
Aquatic Toxicity: Harmful to aquatic life at moderate concentrations; LC50 (fish) estimated around 10-100 mg/L (96h)
Persistence and Degradability: Not readily biodegradable in soil or water; may persist for extended periods
Bioaccumulation: Potential for bioaccumulation in aquatic organisms, log Kow >4 suggests moderate concern
Mobility: Moderate volatility and high mobility in soil, limited water solubility, potential for vapor-phase transport
Waste Disposal: Collect in suitable containers for disposal at licensed hazardous waste site
Recycling: Consult local facilities that accept organic chemical wastes for treatment or energy recovery
Local Regulations: Follow national and regional environmental guidelines for hydrocarbon waste disposal; do not release into sewers or environment
