Isobutenylacetat

Isobutenylacetat, also known as 3-methylbut-1-en-1-yl acetate or isoamylene acetate, is a chemical compound with the molecular formula C6H10O2. It is an ester derived from isobutenyl alcohol and acetic acid. This compound is a colorless liquid with a characteristic fruity odor. It is soluble in many organic solvents but has limited solubility in water.

Isobutenylacetat can be synthesized through the esterification reaction between isobutenyl alcohol and acetic acid in the presence of an acid catalyst. It can also be formed by the reaction of isobutene with acetic acid or acetic anhydride. The specific synthesis route can influence the purity and yield of the final product.

This ester finds applications primarily as a flavoring agent and fragrance ingredient in the food and cosmetic industries. Its fruity aroma makes it suitable for use in various food products, such as candies, baked goods, and beverages, to impart or enhance fruit-like notes. In perfumery and personal care products, it contributes to the overall scent profile.

Due to its volatility and characteristic smell, isobutenylacetat is sometimes used as a solvent, although this is a less common application compared to its use in flavors and fragrances. Like many organic esters, it is generally considered to be flammable and should be handled with appropriate safety precautions. Information regarding its specific toxicity and environmental impact is available in safety data sheets and chemical databases.
