Isoamyl acetate, also known as
isopentyl acetate, is an
organic compound that's the
ester formed from
isoamyl alcohol and
acetic acid. It is a clear colorless liquid that's only slightly soluble in water, but very soluble in most organic solvents.
Isoamyl acetate has a strong odor (similar to juicy fruit) which is also described as similar to both
banana and
pear.
Banana oil is a term that's applied either to pure isoamyl acetate or to flavorings that are mixtures of isoamyl acetate,
amyl acetate,
nitrocellulose and other flavors.
Pear oil commonly refers to a solution of isoamyl acetate in
ethanol that's used as an artificial flavor.
Isoamyl acetate is also used to test the effectiveness of
respirators or
gas masks because it has a strong smell which is generally not experienced as unpleasant that can be detected at low concentrations, and has low toxicity.
It is also used as a solvent for some varnishes and nitrocellulose lacquers, as well as being a honey bee
pheromone and can be used to attract large groups of honeybees to a small area.
Isoamyl acetate is released by a
honey bee's
sting apparatus where it serves as a
pheromone beacon to attract other bees and provoke them to sting.
Laboratory Synthesis
Isoamyl acetate can be prepared in the laboratory by the acid catalyzed
Fischer esterification reaction between
isoamyl alcohol and glacial
acetic acid as shown in the reaction equation below. Typically, concentrated
sulfuric acid is used as the
catalyst. The reactants are
refluxed in order to promote the reaction, the acid is neutralized and extracted, and the product is dried, then distilled.
