| Chemical Properties | clear liquid |
| Uses | Butyl Vinyl Ether is a reagent used in organic chemical reactions and the preparation of pharmaceutical compounds used in anticancer therapy. It is also used in the synthesis of potent inhibitors for PDE5. It is also used in the synthesis of copolymers and as an acrylic/vinyl acetate resin comonomer. |
| Uses | Synthesis, copolymerization. |
| Manufacturing Process | (1) It is derived from the reaction of acetylene and butanol. This method requires less equipment and high selectivity. (2) It is obtained by the reaction of acetaldehyde and n-butanol. This method of cleavage from acetal is also a common process for vinyl ethers. Another relatively new method is the reaction of alcohol, ethylene and oxygen in the presence of palladium chloride-copper chloride catalyst to give n-Butyl vinyl ether. |
| General Description | A 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 Reactions | Highly 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 Profile | Ethers, 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 Hazard | Inhalation 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 Hazard | HIGHLY 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. |
| Flammability and Explosibility | Highlyflammable |
| Safety Profile | Mildly 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. |

| Shipping | UN2352 Butyl vinyl ether, stabilized, Hazard
Class: 3; Labels: 3—Flammable liquid. |
| Purification Methods | After 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.] |
| Incompatibilities | Vapors 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, |
