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.
Claims7
A method of producing a mixture of decyl alcohols comprising oligomerization of propylene, catalyzed by deactivated zeolite, to form an oligomer mixture comprising 9 carbon olefins, separation of said 9 carbon olefins from said oligomer mixture, hydroformylation of said 9 carbon olefins to 10 carbon aldehydes, and hydrogenation of said aldehydes to said decyl alcohols.
