Abstract: Aldehydes are produced by hydroformylation of olefins using a dissolved homogeneous catalyst comprising a special Group VIII metal-polyamine complex, followed by distillation of products with removal of high-boiling components from the sump and recycling of catalyst and excess ligand. A process for the production of aldehydes or aldehydes and alcohols comprises the hydroformylation of olefins at 50-100 deg C and 20-1000 bar in presence of a homogeneous (dissolved) complex catalyst. This catalyst contains a Group VIII metal and a phosphorus-free, multi dentate ligand consisting of a derivatized, essentially water-insoluble polyamine with an average mol.wt of more than 1000 and at least 10 nitrogen atoms. After the reaction, the catalyst complex and excess ligand are returned to the hydroformylation reaction after complete or partial removal of aldehydes and alcohols by distillation, and at least part of the high-boiling component is continuously or at least intermittently removed from the distillation sump. An Independent claim is also included for a hydroformylation catalyst complex with a Group VIII metal as central atom and, as ligands, at least one carbonyl group and at least one polyamine as above.

Abstract: The invention concerns the electrochemical preparation of dicarboxylic acids by subjecting an aqueous solution containing essentially the alkali-metal salt of a dicarboxylic acid of the general formula (I): HOOC-(CH2)n-COOH, in which n may be an integer from 1 to 8, or mixtures of such dicarboxylic acids, to an electrochemical treatment.
