Hoechst Aktiengesellschaft 6230 Frankfurt am Main 80 Abstract of the disclosure Mixtures of isomeric nonanols and decanols are obtained by joint aldol condensation of n-butanal and pentanals (these are mixtures of from 60 to 90% by weight of n-pentanal, from 10 to 40% by weight of 2-methylbutanal and up to 1% by weight of 3-methylbutanal), hydrogenation of the aldol condensation product to the saturated alcohols and removal from the reaction mixture of the components boiling at lower temperatures than the nonanols and decanols. The alcohol mixture is especially suitable for preparing ester plasticizers.
