Name: N-Butyl Vinyl Ether Chemical Formula: C6H12O CAS Number: 111-34-2 Appearance: Clear, colorless, volatile liquid with a distinct, ether-like smell Common Uses: Solvent, intermediate for polymers, chemical synthesis. Odor Threshold: Noticeable at relatively low concentrations, sharp and sweet Boiling Point: Roughly 94-95°C Molecular Weight: About 100 g/mol Solubility: Limited in water, mixes well with organic solvents
Classification: Flammable liquid, irritant, harmful by inhalation and skin contact Hazard Statements: Flammable liquid and vapor, causes eye and skin irritation, may cause respiratory irritation, suspected of damaging fertility or the unborn child based on structural analogs Pictograms: Flame, exclamation mark, health hazard Precautionary Statements: Keep away from heat, sparks, open flames; avoid breathing vapors; use in a well-ventilated area; wear protective gloves and eye protection Routes of Exposure: Inhalation, skin and eye contact, accidental ingestion Potential Symptoms: Dizziness, headache, nausea, skin redness, eye watering
Component: N-Butyl Vinyl Ether Purity: Typically above 95% Impurities: Traces of stabilizers, possibly peroxides due to storage, minor hydrocarbon contaminants sometimes detected in some batches Synonyms: 1-Butoxyethene
Inhalation: Move user to fresh air at once; keep at rest; if symptoms like coughing, breathlessness, weakness, or confusion develop, seek medical attention quickly Skin Contact: Remove contaminated clothing; rinse skin thoroughly with plenty of water and mild soap for several minutes; if significant irritation or blistering persists, consult medical personnel Eye Contact: Rinse carefully with water for at least 15 minutes; do not rub eye; remove contact lenses if present and easy to do; get medical advice if redness or pain lingers Ingestion: Rinse mouth with water; do not induce vomiting; seek prompt medical help due to risk of gastrointestinal upset and potential toxicity
Suitable Extinguishing Media: Alcohol-resistant foam, dry chemical, carbon dioxide; water spray useful for cooling but may not extinguish alone Unsuitable Extinguishing Media: Direct water jets may spread the fire Specific Hazards: Vapors form explosive mixtures with air above flash point of around -1°C; combustion generates carbon monoxide, carbon dioxide, possibly irritating fumes Protective Equipment: Firefighters require self-contained breathing apparatus, full protective suit Firefighting Advice: Cool containers at risk from fire with water spray from a safe distance; evacuate area; keep unnecessary persons out
Personal Protection: Wear gloves, chemical splash goggles, flame-retardant coveralls, use appropriate respiratory protection if high vapor concentrations Environmental Precautions: Prevent runoff into drains, surface waters, and soil; isolate spill area Methods for Containment/Cleanup: Contain with inert absorbent materials like sand or earth; ventilate area; use nonsparking tools; collect spilled liquid in tightly sealed containers for disposal
Handling: Always use non-sparking tools and grounded equipment; work in chemical fume hood or well-ventilated room; avoid breathing vapors Storage: Store in tightly closed, chemical-resistant containers; keep in a cool, well-ventilated place away from heat, open flame, and oxidizers; add appropriate stabilizer like BHT if required to prevent peroxide formation Compatibility: Incompatible with strong acids, bases, oxidizing agents Specific Practices: Regularly inspect storage containers for leaks or accumulation of peroxides
Exposure Limits: No established OSHA PEL or ACGIH TLV; minimize exposure as much as practicable Engineering Controls: Use local exhaust ventilation or fume hood Personal Protective Equipment: Chemical-resistant gloves, safety goggles, flame-resistant laboratory coat, splash-proof apron Respiratory Protection: Use NIOSH-approved organic vapor respirator if air concentrations may exceed safe levels or where ventilation is inadequate Hygiene Measures: Wash hands and face thoroughly after handling; keep work clothing separate from other laundry; avoid eating, drinking, or smoking around the chemical
Physical State: Liquid Appearance: Transparent, colorless Odor: Sweet, ethereal Melting Point: Near -117°C Boiling Point: Approx. 94-95°C Flash Point: Below 0°C (closed cup) Vapor Pressure: Significant at room temperature; vapor spreads easily Relative Density: 0.75-0.77 (water = 1) Evaporation Rate: Rapid Solubility: Slightly soluble in water, miscible with many organics Viscosity: Low
Chemical Stability: Stable under normal conditions if stored away from heat, light, and oxidizing substances Possibility of Hazardous Reactions: Forms explosive peroxides over time, especially if exposed to air and light; can polymerize violently if contaminated or uninhibited Incompatible Materials: Strong acids, bases, peroxides, oxidizers Decomposition Products: Toxic gases including carbon monoxide and carbon dioxide
Likely Routes of Exposure: Inhalation, skin absorption, eye contact Health Effects: Irritates skin, eyes, respiratory tract; can cause dizziness, headache, nausea at high vapor levels; May affect liver with extended use Acute Toxicity: Data for vinyl ethers suggest moderate acute toxicity; LD50 (oral, rat) variable above 1000 mg/kg Chronic Effects: No clear long-term human data, but concerns about liver toxicity and potential mutagenicity remain based on related compounds Sensitization: Not commonly reported but possible Carcinogenicity: Not known to be classified as a carcinogen by IARC, NTP, or OSHA
Aquatic Toxicity: Harmful to aquatic organisms at higher concentrations; vinyl ethers can impact fish and invertebrates Persistence and Degradability: Expected to be relatively degradable in environment, though volatile loss to air occurs Bioaccumulative Potential: Low to moderate potential due to volatility Mobility in Soil: Considered mobile, especially in sandy or loose soils, may leach to groundwater Other Hazards: Contamination with peroxides poses significant environmental risk if released
Waste Treatment Methods: Collect as hazardous waste; incinerate in licensed facility with appropriate controls to avoid air pollution Precautions: Prevent accidental release during storage and transport; never pour down drain or into surface water Small Quantities: Absorb on inert material and dispose of via chemical waste contractor Contaminated Packaging: Remove excess chemical, triple rinse with appropriate solvent, dispose of both rinsates and container as hazardous waste
UN Number: 2276 (for N-butyl vinyl ether) Proper Shipping Name: Butyl vinyl ether, stabilized Hazard Class: 3 (Flammable liquid) Packing Group: II Marine Pollutant: Not listed as marine pollutant, but care should be taken due to aquatic toxicity Special Precautions: Transport with closed, properly labeled containers; avoid transport with foodstuffs or oxidizers
TSCA: Listed on the US Toxic Substances Control Act inventory REACH: Registered in the European Union; subject to volume and usage restrictions Hazard Labeling: Flammable, harmful, irritant Other Regulations: Subject to specific workplace safety rules, chemical hygiene plans, and possible notification or reporting thresholds Employee Right-To-Know: Employees must receive documented training on hazards and safe use of N-butyl vinyl ether if present in the workplace
