Chemical Name: Ethyl Allyl Ether
Concentration: >98% by weight
CAS Number: 140-88-5
Impurities: Trace stabilizers provided by supplier, minor hydrocarbon residues may be present depending on source
Inhalation: Move person to fresh air immediately, keep comfortable, administer oxygen if breathing is difficult, seek medical help if symptoms persist
Skin Contact: Remove contaminated clothing, wash affected area with plenty of water and mild soap, seek medical advice for persistent irritation
Eye Contact: Rinse eyes for at least 15 minutes with clean water, remove contact lenses after first 1-2 minutes, continue rinsing, seek medical attention
Ingestion: Rinse mouth with water, never induce vomiting unless directed by a medical professional, seek immediate medical advice
Most Important Symptoms: Potential respiratory irritation, dizziness, central nervous system depression, prolonged exposure may aggravate dermatitis or eye conditions
Suitable Extinguishing Media: Carbon dioxide, alcohol-resistant foam, dry chemical powder, water spray (use to cool surfaces only)
Fire Hazards: Vapors may form explosive mixtures with air, can travel long distances to ignition source and flash back
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing
Specific Methods: Remove containers from fire area if safe, cool fire-exposed containers with water spray, avoid runoff from entering waterways
Hazardous Combustion Products: May release carbon monoxide, carbon dioxide, and other toxic fumes during incomplete combustion
Personal Precautions: Evacuate unnecessary personnel, ensure proper ventilation, eliminate ignition sources, wear appropriate personal protective equipment including gloves, goggles, and respirator
Environmental Precautions: Prevent entry into sewers, drains, surface waters, or soil
Containment and Cleanup: Use inert absorbent materials, sweep up and place in a container for disposal, ventilate affected area, wash spill site with soap and water after material pick-up
Handling: Use protective gloves and eye/face protection, avoid inhaling vapors, ensure adequate ventilation in work area, avoid contact with skin and eyes, keep away from sources of ignition - no smoking, use explosion-proof equipment whenever possible
Storage: Store in tightly closed, properly labeled containers, keep in a cool, dry, well-ventilated place, keep away from heat or direct sunlight, segregate from oxidizing agents and acids, ground all equipment containing the material
Exposure Limits: No OSHA or ACGIH exposure limits established for ethyl allyl ether; monitor airborne levels if possible
Engineering Controls: Use fume hoods, local exhaust ventilation, explosion-proof ventilation systems
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, protective clothing, in case of inadequate ventilation use organic vapor respirator
Hygiene Measures: Remove contaminated clothing, wash hands thoroughly before breaks or eating, do not breathe vapors or fumes, avoid all unnecessary exposure

Boiling Point: 90-92 °C at 760 mmHg
Melting Point: -117 °C
Flash Point: -7 °C (closed cup)
Vapor Pressure: 100 mmHg at 25 °C
Vapor Density: 3.1 (air = 1)
Solubility: Slightly soluble in water; miscible with organic solvents such as ethanol, diethyl ether
Density: 0.83 g/cm³
pH: Not applicable
Partition Coefficient (log Kow): 1.46
Evaporation Rate: >1 (butyl acetate = 1)
Odor Threshold: No data available
Chemical Stability: Stable under normal conditions of use and storage, may polymerize if contaminated or exposed to heat or light
Hazardous Reactions: May react violently with strong oxidizers, finely divided metals, acids
Conditions to Avoid: Avoid heat, sparks, sources of ignition, direct sunlight, static discharge
Incompatible Materials: Oxidizing agents, acids, bases, some plastics
Hazardous Decomposition: Produces carbon oxides and toxic vapors during decomposition or combustion
Acute Toxicity: Low oral toxicity in animal studies (estimated LD50 >2000 mg/kg, rats), higher toxicity through inhalation
Skin and Eye Irritation: Causes irritation on contact, repeated or prolonged exposure may worsen symptoms
Respiratory Effects: Inhalation of vapors irritates respiratory tract, central nervous system depression possible with high exposures
Chronic Effects: Frequent skin contact can lead to dermatitis, no clear evidence of carcinogenicity, mutagenicity, or reproductive toxicity in available literature
Sensitization: Not expected to cause sensitization
Toxicity: Harmful to aquatic organisms, experimental data on fish and invertebrates show moderate toxicity
Persistence and Degradability: Not readily biodegradable compared to alcohols; slower breakdown in soil and water
Bioaccumulative Potential: Moderate potential for bioaccumulation based on log Kow values
Mobility in Soil: Likely to volatilize; limited mobility in soil due to moderate water solubility
Other Adverse Effects: Avoid release into environment, spills can contaminate groundwater or surface waters
Waste Treatment Methods: Dispose of as hazardous chemical waste in accordance with local, regional, national, and international regulations
Container Disposal: Triple-rinse empty containers, puncture before recycling or landfilling, follow regulations
Precautions: Do not allow to reach drains, sewers, or water bodies, incineration in a chemical incinerator equipped with afterburner and scrubber preferred for large quantities
