    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.

    摘要: 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.

    摘要: Epoxidized polybutadienes with an average molecular weight of 500 to 100,000 and a certain content of epoxide oxygen were prepared from the corresponding polybutadienes with use of perpropionic acid in a benzene solution. The solution can also be employed in unpurified form with maximum contents of 1.5 weight percent hydrogen peroxide 1.5 weight percent of water, and about 800 ppm of mineral acid.
