Name: 1-Decene
Chemical Formula: C10H20
Common Use: Starting material for synthetic lubricants, plasticizers, surfactants, and more
Physical State: Colorless liquid at room temperature
Odor: Mild, sweet
Molecular Weight: 140.27 g/mol
CAS Number: 872-05-9
Hazard Statements: Flammable liquid and vapor; may cause skin and eye irritation; inhalation of vapors can affect the respiratory system
Pictograms: Flame, Exclamation Mark
Routes of Exposure: Skin, eyes, inhalation, ingestion
Potential Health Effects: Prolonged or repeated contact may dry skin or cause dermatitis; high concentrations of vapor might cause dizziness and headaches
Hazard Class: Flammable liquids, Category 3; Skin irritant, Category 2
Component: 1-Decene, typically over 98% by weight
Impurities: Other alkenes, minor isomeric forms
Inhalation: Move to fresh air right away; support breathing if symptoms like coughing or dizziness show up
Skin Contact: Wash with soap and water immediately; take off any contaminated clothing
Eye Contact: Rinse with plenty of clean water for several minutes
Ingestion: Do not induce vomiting; rinse mouth and seek medical attention if feeling unwell or if large amounts were swallowed
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, alcohol-resistant foam
Special Hazards: Burning gives off carbon monoxide, carbon dioxide, and possibly other hydrocarbons
Firefighting Instructions: Use protective gear, keep containers cool with water spray; approach from upwind to avoid inhaling vapors
Explosion Risk: Forms flammable mixtures with air; vapors can travel and ignite
Personal Precautions: Remove sources of ignition, ventilate area, wear gloves and goggles
Environmental Precautions: Prevent further leakage or spillage into soil, drains, or water
Cleanup Methods: Use non-sparking tools to absorb with sand, earth, or inert material; collect in sealed containers for disposal
Precautions: Keep away from heat, sparks, open flames; use local exhaust and avoid breathing vapors
Safe Storage: Store in tightly closed containers in cool, well-ventilated areas; separate from oxidizers
Incompatible Materials: Strong oxidizing agents; avoid storage under direct sunlight
Engineering Controls: Use fume hoods or mechanical ventilation
Personal Protection: Wear protective gloves, safety goggles, and flame-resistant lab coats; use a face shield for splash risk
Respiratory Protection: Use approved respirators if exposure limit may be exceeded or if ventilation is inadequate
Workplace Exposure Limits: No established occupational limits for 1-decene, but minimizing inhalation, skin, and eye contact makes sense for long-term health
State: Liquid
Boiling Point: Roughly 170 to 174°C
Melting Point: About -66°C
Flash Point: Around 67°C (open cup method)
Vapor Pressure: Low, but increases at higher temperatures; vapors heavier than air
Solubility: Not miscible with water; dissolves in organic solvents
Density: Close to 0.74 g/cm³
Volatility: High enough to build up in closed environments, so ventilation is important
Chemical Stability: Stable under normal use and storage conditions
Conditions to Avoid: Heat, sparks, open flames, and contact with strong oxidizers
Hazardous Reactions: Can form explosive peroxides with prolonged air exposure; reacts with strong acids and oxidizing materials
Hazardous Decomposition Products: Burning produces carbon oxides and, in some cases, other noxious gases
Acute Toxicity: Inhalation may irritate respiratory tract; skin contact can dry or crack skin
Chronic Exposure: Prolonged, repeated exposure can worsen dermatitis and make skin more sensitive
Carcinogenicity: No reputable studies link 1-decene itself to cancer
Other Effects: Ingesting large amounts may result in gastrointestinal distress; exposure above recommended levels causes headache, nausea, dizziness; those with pre-existing skin or respiratory conditions may be more susceptible to effects
Aquatic Toxicity: Harmful for aquatic species, especially with larger spills
Persistence / Degradability: Slowly degrades in the environment, though it can break down under the right conditions
Bioaccumulation: Has the potential to build up in aquatic organisms
Soil Mobility: Tends to float on water and spreads easily on soil surfaces, making quick containment vital to prevent runoff
Disposal Methods: Incineration in approved facilities; do not pour into drains, surface water, or soil
Container Handling: Empty container may still hold flammable vapors; follow local and federal laws for both liquid and container disposal
UN Number: 1993
Proper Shipping Name: Flammable Liquid, N.O.S. (Contains 1-Decene)
Hazard Class: 3 (Flammable liquid)
Packing Group: III
Transport Precautions: Keep containers tightly sealed, separated from foodstuffs, and away from heat sources; secure during transportation to prevent tipping or leaks
Regulations: Listed on various national and international chemical inventories including TSCA (US), DSL (Canada), and REACH (EU). Depending on jurisdiction, reporting and record-keeping requirements may apply.
Labeling: Standard safety and hazard labels, with pictograms and risk phrases related to flammability and irritation
