MIXTURES OF ISOMERIC DECYL ALCOHOLS, PHTHALATES OBTAINABLE THEREFROM, AND THEIR USE AS PLASTICIZERS

摘要

6230 Frankfurt, 29.06.1992 PAT/rcht-dbh Hoe92/Y012 Hoechst Aktiengesellschaft, Frankfurt am Main 80 of the disclosure: Mixtures of isomeric decyl alcohols are obtained by oligomerization of propylene in the presence of deactivated zeolites as catalysts, separation of the C9-olefins from the oligomer mixture, hydroformylation of the C9-olefins to C10-aldehydes, and hydrogenation of the C10-aldehydes. The mixtures, when esterified with phthalic acid, provide a mixture of isomeric di-decyl phthalates that can be used as plasticizers.
