Abstract: A single-stage process is described that includes simultaneously, in a mixture containing an olefin; synthesis gas; a cobalt catalyst in an organic phase; and an aqueous cobalt salt solution; hydroformylating the olefin, and forming and extracting into the organic phase the cobalt catalyst from the aqueous cobalt salt solution. An apparatus is also described that includes a means for carrying out the process. The process is particularly suitable for preparing aldehydes and alcohols.

Abstract: Process for the production of 2-aryl-1,3-propanediols and novel intermediate compounds produced thereby.

Abstract: CONSTRUCTION The present invention relates to an industrial purification process in the process of manufacturing alcohols and ketones by oxidation of hydrocarbon wherein after removing by extraction organic impurities, formed as by-products of an oxidation reaction, from aqueous boric acid solution obtained by hydrolysis of an oxidation reaction solution containing boric acid ester, obtained by performing an oxidation reaction in the presence of boric acid, in order to essentially regenerate boric acid and prevent lowering of the reaction rate, selectivity and excessive soiling of the apparatus in the case of cyclically using said regenerated boric acid in an oxidation reaction, boric acid is regenerated and cyclically used again in said hydrocarbon oxidation reaction.

Abstract: The present invention is directed to a process and apparatus for synthetically producing .sup.15 O-labeled butanol for position emission tomography. A procedure and apparatus have been developed for the routine rapid and sequential synthesis of oxygen-15 labeled butanol in the amounts and with the purity suitable for use in clinical position tomography. This procedure can replace oxygen-15 labeled water which is more commonly used for routine application, as well as the prior art processes for producing oxygen-15 labeled butanol.

Abstract: Production of an alken-2-ol-1, or of an alken-2-ol-1 and an alkanol-1 from the corresponding alken-3-ol-1 is described. The above compound or compounds can be produced with good selectivity by converting an alken-3-ol-1 to the boric acid ester, and, then, contacting the ester with a palladium catalyst in the presence of hydrogen or, alternatively, by carrying out the latter-mentioned step under conditions favorable to the formation of said boric acid ester and, thereafter, subjecting the reaction product to solvolysis.
