Octyl acetate, or octyl ethanoate, is an organic compound with the formula CH3(CH2)7O2CCH3. It is classified as an ester that is formed from 1-octanol (octyl alcohol) and acetic acid. It is found in oranges, grapefruits, and other citrus products. [10]

Octyl acetate can be synthesized by the Fischer esterification of 1-octanol and acetic acid:

CH3(CH2)7OH + CH3CO2H → CH3(CH2)7O2CCH3 + H2O

Uses

Because of its fruity odor, [11] octyl acetate is used as the basis for artificial flavors and in perfumery. It is also a solvent for nitrocellulose, waxes, oils, and some resins.

In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO2H, sometimes as R−C(O)OH with R referring to the alkyl, alkenyl, aryl, or other group. Carboxylic acids occur widely. Important examples include the amino acids and fatty acids. Deprotonation of a carboxylic acid gives a carboxylate anion.

In chemistry, an ester is a compound derived from an acid in which the hydrogen atom (H) of at least one acidic hydroxyl group of that acid is replaced by an organyl group. Analogues derived from oxygen replaced by other chalcogens belong to the ester category as well. According to some authors, organyl derivatives of acidic hydrogen of other acids are esters as well, but not according to the IUPAC.
