n-Butyl vinyl ether Usage And Synthesis
  • Chemical Propertiesclear liquid
  • UsesSynthesis, copolymerization.
  • General DescriptionA liquid. Flash point 0°F. Less dense than water. Vapors heavier than air. May irritate skin and eyes. Used to make other chemicals.
  • Air & Water ReactionsHighly flammable. Slightly soluble in water; soluble in alcohol and ether. Ethers tend to form unstable peroxides when exposed to oxygen. Ethyl, isobutyl, ethyl tert-butyl, and ethyl tert-pentyl ether are particularly hazardous in this respect. Ether peroxides can sometimes be observed as clear crystals deposited on containers or along the surface of the liquid.
  • Reactivity ProfileEthers, such as BUTYL VINYL ETHER can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
  • Health HazardInhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution.
  • Fire HazardHIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
  • Safety ProfileMildly toxic by ingestion, skin contact, and inhalation. A skin and eye irritant. A very dangerous fire hazard when exposed to heat or flame. To fight fire, use foam, CO2, dry chemical, alcohol foam. Moderately explosive by spontaneous chemical reaction. Can react with oxidizing materials. When heated to decomposition it emits acrid smoke and irritating fumes. See also ETHERS.
  • Potential ExposureButyl vinyl ether is an extremely flammable, colorless liquid. ether like odor. Molecular weight 5 100.2; specific gravity (H2O:1) 5 0.8; boiling point 5 94C; freezing/melting point 5 2112.8C; vapor density (air 5 1) 5 3.5; flash point 5 29.4C (oc); Autoignition temperature 5 255C. Hazard identification (based on NFP A-704 M Rating System): Health 2; flammability 3; reactivity 1 ?. Slightly soluble in water
  • ShippingUN2352 Butyl vinyl ether, stabilized, Hazard Class: 3; Labels: 3—Flammable liquid.
  • Purification MethodsAfter five washings with equal volumes of water to remove alcohols (made slightly alkaline with KOH), the ether is dried with sodium and distilled under vacuum, taking the middle fraction [Coombes & Eley J Chem Soc 3700 1957]. Store it over KOH. [Beilstein 1 IV 2052.]
  • IncompatibilitiesVapors may form explosive mixture with air. Moderately explosive by spontaneous chemical reaction. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids,
