Chemic compound

Isoamyl acetate, too known as isopentyl acetate, is an organic compound that is the ester formed from isoamyl alcohol and acetic acid. It is a colorless liquid that is only slightly soluble in h2o, but very soluble in most organic solvents. Isoamyl acetate has a strong odor which is described as like to both banana and pear.^[3] Pure isoamyl acetate, or mixtures of isoamyl acetate, amyl acetate, and other flavors may be referred to every bit banana oil.^[4]

Production [edit]

Isoamyl acetate is prepared by the acid catalyzed reaction (Fischer esterification) between isoamyl booze and glacial acerb acid as shown in the reaction equation below. Typically, sulfuric acid is used as the catalyst. Alternatively, p-toluenesulfonic acid or an acidic ion commutation resin can exist used equally the catalyst.

Applications [edit]

Isoamyl acetate is used to confer banana or pear flavor in foods.^[v] Banana oil commonly refers to a solution of isoamyl acetate in ethanol that is used as an bogus season.

It is also used as a solvent for some varnishes and nitrocellulose lacquers. As a solvent and carrier for materials such as nitrocellulose, information technology was extensively used in the shipping manufacture for stiffening and air current-proofing fabric flying surfaces, where it and its derivatives were generally known equally 'aircraft dope'. Now that most aircraft wings are made of metal, such use is more often than not limited to historically accurate reproductions and scale models.

Because of its intense, pleasant olfactory property and its depression toxicity, isoamyl acetate is used to test the effectiveness of respirators or gas masks.^[vi]

Occurrence in nature [edit]

Isoamyl acetate occurs naturally in the banana plant^[seven] and it is also produced synthetically.^[8]

Isoamyl acetate is released past a honey bee'southward sting apparatus where information technology serves as a pheromone beacon to attract other bees and provoke them to sting.^[ix]
