Isobutyl benzoate is an organic compound belonging to the class of benzoate esters. Its chemical formula is C11H14O2. It is formed by the esterification of benzoic acid with isobutanol (2-methylpropan-1-ol). Here are some key points about isobutyl benzoate:
Chemical Structure
Isobutyl benzoate consists of a benzene ring (benzoyl group) bonded to an isobutyl group at the esterified position. The isobutyl group is derived from isobutanol, which is a branched-chain alcohol.
Appearance and Odor
Isobutyl benzoate is typically a colorless to pale yellow liquid with a mild, sweet, and slightly fruity odor. Its fragrance profile makes it suitable for use in perfumery and fragrance applications.
Fragrance Industry
Isobutyl benzoate is primarily used as a fragrance ingredient due to its pleasant odor profile. It is commonly employed in perfumes, colognes, lotions, soaps, and other personal care products to impart sweet and fruity notes.
Solvent
In addition to its use in fragrances, isobutyl benzoate can serve as a solvent in various applications, including inks, coatings, and cleaning products.
Synthesis
Isobutyl benzoate can be synthesized through the esterification reaction between benzoic acid and isobutanol in the presence of an acid catalyst, such as sulfuric acid or p-toluenesulfonic acid. The reaction typically occurs under reflux conditions, and the resulting product is then purified and isolated through distillation or other separation techniques.
Overall, isobutyl benzoate is valued for its mild and fruity fragrance profile and finds application in the fragrance and cosmetic industries, as well as in other sectors where its odor properties are advantageous.
