Abstract
A process for the production of 1,12-dodecanoic diacid by hydroformylating an unsaturated carboxy compound in the presence of a rhodium catalyst and oxidation of the aldehyde with oxygen, wherein undecyl-10-ene-acid is hydroformylated in the presence of hydridotristriphenylphosphine-rhodium-carbonyl combined with triphenylphosphine and/or triphenylphosphite, and the 11-formyl undecanioc acid which is thus formed is oxidized with oxygen in the presence of inorganic and organic Co(II) salts.
