Colorless liquid. Very slightly soluble in water; soluble in alcohol and ether; easily polymerized.??
Isobutyl vinyl ether is use in preparation method and formula of bulk polymerized Chloroether resin.?? ??
A clear colorless liquid. Flash point 15°F. May polymerize if contaminated or subjected to heat. If polymerization take place inside a container, the container may violently rupture. Vapors are heavier than air.??? ?? ??
Highly flammable. Less dense than water and very slightly soluble in water. Tends to form explosive peroxides when exposed to air. When ethers containing peroxides are heated (distilled) they can detonate [Lewis, 3rd ed., 1993, p. 728].?? ???
Isobutyl vinyl ether is a colorless, moderately toxic liquid, highly flammable. A very dangerous fire hazard when exposed to heat, flame or strong oxidizing agents. Highly explosive in the form of vapor when exposed to open flame or sparks.????
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.????
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.Properties and Applications
Isobutyl vinyl ether (IBVE) has a carbon–carbon double bond and is chemically active. It can react with a wide variety of substances to form various derivatives. IBVE is stable to alkalis but readily hydrolyzes to isobutanol and acetaldehyde under acidic conditions. Therefore, it is often stabilized by addition of a small amount of base such as triethanolamine.Purification Methods
Wash the ether three times with equal volumes of aqueous 1% NaOH, dry with CaH2, reflux it with sodium for several hours, then fractionally distil it from sodium. [Beilstein 1 IV 2054.]???? ?? ??? ?? ?? ? ???
