Commercial processes for the production of isoamyl alcohol include fractionation of fusel oils, chlorination of [C.sub.5]- alkanes with subsequent hydrolysis to produce a mixture of isomers and a low pressure oxo-process or hydroformylation of n-butenes followed by hydrogenation of the resultant iso-valeraldehyde (Kirk and Othmer, 2004).
