OriginAmyl acetate is synthesized from amyl alcohol and acetic acid, both derived from petroleum or fermentation sources. It is produced through esterification, where acetic acid reacts with amyl alcohol in the presence of a catalyst.
N-amyl acetate appears as a mixture of isomers. A clear colorless liquid with a banana-like odor. Flash point varies from 65 °F to 95 °F. Less dense (at 7.2 lb / gal) than water and slightly soluble in water. Hence floats on water. Vapors heavier than air.
