Abstract
Process for the manufacture of polyene aldehydes, which consists in selectively reducing an aldehyde of the general formula ** (See formula) ** wherein n means an integer ranging from 1 to 7, and R means alternatively the methyl group and a hydrogen atom (initially, the methyl group), or an acetal thereof in the triple bond and, if desired, in isomerizing the product (after hydrolysis in the case of an acetal).
