ABSTRACT:
Mixtures of isomeric decyl alcohols obtained by oligomerization of propylene in the presence of deactivated zeolites as catalysts, followed by separation of the nine carbon olefins from the oligomer mixture, then hydroformylation of the 9 carbon olefins to 10 carbon aldehydes, and hydrogenation of the aldehydes to the corresponding alcohols. The mixtures, when esterified with phthalic acid, or anhydride, provide a mixture of isomeric di-decyl phthalates that can be used as plasticizers.
