How it is made

By hydrogenation of valeric aldehyde with sodium amalgam, from amyl chloride.

Fractional distillation of mixed alcohols resulting from the chlorination and alkaline hydrolysis of pentane

Commercial processes for the production of amyl alcohols include separation from fusel oils, chlorination of C-5 alkanes with subsequent hydrolysis to produce a mixture of seven of the eight isomers ... and a low pressure oxo process, or hydroformylation, of C-4 olefins followed by hydrogenation of the resultant C-5 aldehydes. (Amyl Alcohols)
