Ingredient: Vinyl Ethyl Ether
Concentration: 99% minimum, stabilized with inhibitors such as BHT at under 0.1%
Impurities: Traces of peroxides from storage, minor amounts of water and aldehydes from decomposition if exposed to air
Mixture or Substance: Substance
Inhalation: Remove to fresh air, provide oxygen if breathing is difficult, seek medical attention for persistent symptoms
Skin Contact: Immediately remove contaminated clothing, wash thoroughly with soap and water, seek medical help if irritation develops
Eye Contact: Rinse opened eye with plenty of water for at least 15 minutes, lift eyelids occasionally, consult an eye specialist
Ingestion: Rinse mouth with water, do not induce vomiting, get medical help immediately, monitor for chemical pneumonia or respiratory symptoms
Most Important Symptoms: CNS effects like headache, nausea, respiratory tract irritation, chemical burns to tissues
Notes for Physicians: Treat by symptomatic and supportive therapy, monitor respiratory function
Suitable Extinguishing Media: Dry chemical, CO2, foam recommended, use water spray to cool fire-exposed containers
Unsuitable Extinguishing Media: Straight water streams may cause spread of burning liquid
Special Fire Hazards: Produces hazardous gases such as carbon monoxide and carbon dioxide, vapors may travel and flash back
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear
Other Precautions: Evacuate and isolate area, cool containers located in fire with water, avoid breathing combustion products
Personal Precautions: Remove ignition sources, ventilate area, use personal protective equipment including gloves and goggles
Spill Cleanup Methods: Absorb with inert materials like sand, place in chemical waste container, do not allow into drains
Environmental Precautions: Prevent spill from entering waterways, sewers, soil contamination, notify authorities of large spills
Emergency Procedures: Evacuate non-essential staff, restrict access, use non-sparking tools for cleanup
Handling: Handle in chemical fume hood or well-ventilated area, avoid breathing vapors or contact with skin and eyes, keep away from static or open flames, ground containers
Storage: Store tightly closed in cool, well-ventilated location, away from sources of ignition, segregated from oxidizers and acids, keep under nitrogen if possible, check inhibitor levels regularly, store in dark glass or metal containers designed for flammable liquids
Special Requirements: Monitor vapor concentrations, use flammable liquid storage cabinets, label containers clearly
Incompatible Materials: Strong oxidizers, acids, bases, peroxides, avoid copper or copper alloys as they catalyze decomposition
Occupational Exposure Limits: No established OSHA or ACGIH limit; work under threshold of strong solvent vapors, use industrial hygiene monitoring
Engineering Controls: Local and general ventilation recommended, explosion-proof exhaust systems for higher volumes, use closed systems for process handling
Personal Protective Equipment: Protective gloves made of nitrile or neoprene, chemical splash goggles, lab coat or apron, flame-resistant clothing in larger-scale settings
Respiratory Protection: Use organic vapor respirator if ventilation inadequate, in emergencies or unknown vapor concentrations use supplied air or SCBA
Hygiene Practices: Wash hands and skin after handling, separate eating/drinking areas from work areas, launder clothing regularly
Appearance: Clear, volatile, colorless liquid
Odor: Mild, sweet ether-like odor
Molecular Weight: 72.11 g/mol
Boiling Point: 34–35°C (93–95°F)
Melting Point: -116°C (-177°F)
Vapor Pressure: 313 mmHg at 20°C, generates significant vapor
Flash Point: -25°C (-13°F) (closed cup)
Flammability: Easily ignitable, forms explosive air-vapor mixtures
Autoignition Temperature: Approx. 180–200°C (356–392°F)
Solubility: Slightly soluble in water, mixes readily with organic solvents
Density: 0.71 g/cm3 at 20°C
Partition Coefficient (log Kow): 0.91 estimated
Viscosity: Low, flows like water
Chemical Stability: Stable in presence of stabilizer, sensitive to light, heat, air, and peroxides
Conditions to Avoid: Ignition sources, heat, sunlight, storage without stabilizer, mixing with strong acids or oxidizers
Incompatible Materials: Strong oxidizing agents, acid chlorides, bases, copper or alloys containing copper, peroxides
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, aldehydes, possible ethylene or other unsaturated compounds
Polymerization: May occur if inhibitor is depleted or heated, resulting in exothermic reaction

Skin Contact: May cause mild to moderate irritation, repeated or prolonged contact can defat skin
Eye Contact: Severe irritation, redness, tearing
Ingestion: Symptoms mimic alcohol or ether intoxication, can depress central nervous system, vomiting, drowsiness
Chronic Effects: No definite chronic effects outlined, monitor for signs of repeated exposure or allergic reaction
Carcinogenicity: Not classified as carcinogenic by NTP, IARC, or OSHA
Mutagenicity: No available evidence for mutagenic action
Reproductive Effects: No known direct effect on reproductive health but avoid exposure during pregnancy as precaution
Environmental Impact: High volatility leads to rapid evaporation from soil or water surfaces, product can contribute to photochemical smog
Aquatic Toxicity: Fish and invertebrate studies show moderate toxicity at high concentrations, quickly disperses and degrades when exposed to sun and air
Persistence and Degradability: Degrades through atmospheric oxidation, half-life estimated at less than 10 days in open environment
Bioaccumulation: Low potential, log Kow under 1, unlikely to concentrate in living organisms
Mobility in Soil: Moves rapidly through soil due to volatility, will not persist long in groundwater
Other toxicity: No evidence of chronic harm to aquatic life at realistic environmental exposures, precaution for industrial releases still warranted
Waste Treatment Methods: Dispose by incineration in approved chemical waste facility, do not pour into drains or ground
Contaminated Packaging: Rinse with compatible solvent, then destroy container by puncturing or approved means
