Abstract: Mixtures of isomeric decyl alcohols are obtained by hydroformylation of 1-butene- and 2-butene-containing mixtures in two stages to give aldehyde mixtures, condensation of the isolated and combined aldehyde mixtures to form an aldol mixture, and isolation and hydrogenation of the aldol mixture. The mixture of isomeric decyl alcohols, esterified with phthalic acid, gives a mixture of isomeric decyl phthalates which are useful as plasticizers.

Abstract: The recovery of rhodium, present as a homogeneous dissolved complex compound especially in residues of products of the oxo process, is carried out in a two-stage process. In the first stage, the residues are treated with a gas-containing oxygen in the presence of a C2- to C4- monocarboxylic acid and an alkali metal salt of a C2- to C4-monocarboxylic acid, and are then extracted with water. In the second reaction stage, they are treated again with a gas-containing oxygen, an aldehyde, a C2- to C4-monocarboxylic acid, and an alkali metal salt of a C2 to C4 monocarboxylic acid, and are extracted once more with water.

Abstract: The present invention relates to a process for recovering rhodium from aqueous solutions containing rhodium complex compounds and, where appropriate, complex ligands, in the presence of a water-soluble salt of a carboxylic acid, by treatment of the aqueous solution at 20 to 120 DEG C with hydrogen peroxide or a substance forming hydrogen peroxide and with oxygen or an oxygen-containing gas. The rhodium is subsequently separated off as water-insoluble compound.
