• 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.
• Uses: Reagent for acylation of potential enols. 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.
