Abstract

Mixtures of isomeric decyl alcohols prepared by hydroformylation of mixtures of butene-1 and butene-2 in two stages to give aldehyde mixtures, and condensation of the aldehyde mixtures to form an aldol mixture, followed by separation and hydrogenation. The first stage of the hydroformylation proceeds in the presence of rhodium catalysts dissolved in water, the second stage in the presence of cobalt catalysts homogeneously dissolved in the reaction medium. The mixture of isomeric decyl alcohols, when esterified with phthalic acid, yields a mixture of isomeric decyl phthalates which are useful as plasticizers.
