ChEBI: A fatty acid ester obtained by the formal condensation of the carboxy group of hexanoic acid (caproic acid) with the alcoholic hydroxy group of 3-methylbutan-1-ol (isoamylol).

Preparation

By esterification of caproic acid with the isomeric amyl alcohols obtained from fusel oil and other sources.

Production Methods

Isoamyl hexanoate is prepared by direct esterification of the iso-Amyl alcohol with Caproic ( = Hexanoic) acid under azeotropic conditions.
