Process for the production of 1,12-dodecanoic diacid |
摘要 |
A process for the production of 1,12-dodecanoic diacid by hydroformylating an olefin in the presence of a rhodium catalyst and oxidation with oxygen of the aldehyde which is thus formed wherein 1,9-decadiene is hydroformylated in the presence of hydridotris-triphenylphosphine-rhodium-carbonyl combined with triphenylphospine and/or triphenylphosphite, and the 1,12-dodecanedialdehyde which was thus formed is oxidized with oxygen in the presence of inorganic or organic Co(II) salts.
