Abstract of the disclosure Mixtures of isomeric decyl alcohols are prepared by hydroformylation of 1-butene- and 2-butene-containing mixtures in two stages to give aldehyde mixtures, conden- sation of the aldehyde mixtures, separated off and combined, with formation of an aldol mixture and separat- ing off and hydrogenating the aldol mixture. 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 used as plasticizers.
