Description
Isopropenyl acetate is a kind of organic compound, corresponding to the acetate ester of the enol tautomer of acetone. It appears as a clear, colorless liquid with a fruit-like odor. It has a moderate solubility in water and a low flash point. It has a lower density than water but heavier vapor than the air. It is widely used as an industrial and consumer based solvent. For example, it is used as the principal precursor to acetylacetone and some other important chemicals. It can also be used as a kind of food additive. Moreover, it is also applied to coatings, cleaning fluids and printing inks as well as used as cosmetic and personal care solvent and fragrance solvents. It has various kinds of advantages including being a good resin solvent, belonging to a Non-HAP (hazardous air pollutant solvent), having mild odor and undergoing fast evaporating. It is manufactured through treatment of acetone with ketene. However, it is highly flammable and of certain toxicity, therefore proper protective measures should be used during the operation.

Chemical Properties
clear colorless to very slightly yellow liquid
Uses
Iodine in isopropenyl acetate is a unique catalyst for the acetylation of a variety of alcohols, phenols and amines under solvent free conditions. It is used as a solvent for cellulose, plastics, oil and fats. It is also a building block used for various organic synthesis.
Uses
Reagent for acylation of potential enols.

General Description
A clear colorless liquid. Flash point near 60°F. Boiling point near 200°F. Less dense than water. Vapors heavier than air. Used to make other chemicals.
Air & Water Reactions
Highly flammable. Soluble in water.
Reactivity Profile
Isopropenyl acetate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Hazard
Flammable, dangerous fire risk.
Health Hazard
May cause toxic effects if inhaled or absorbed through skin. Inhalation or contact with material may irritate or burn skin and eyes. Fire will produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water 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
Flammable
Safety Profile
Moderately toxic by
ingestion. A skin, eye, and mucous
membrane irritant. A very dangerous fire
hazard when exposed to heat or flame; can
react vigorously with oxidizing materials. To
fight fire, use alcohol foam, CO2, dry
chemical. When heated to decomposition it
emits acrid smoke and irritating fumes.
