    摘要: Ruthenium-cobalt carbonyl catalysts which have been promoted with an organophosphite effectively catalyze the dealkoxyhydroxymethylation of aldehyde acetals to form glycol monoethers. Methylal, for example, may be reacted with syngas, i.e., CO and H.sub.2, in the presence of this phosphite-promoted ruthenium carbonyl cobalt catalyst to form the monomethyl ether of ethylene glycol. In a like manner acetaldehyde may be converted to the corresponding propylene glycol monoether. The process may advantageously be carried out with high yields and selectivities in the presence of a polar or non-polar organic solvent in combination with the catalyst system of this invention.The invention is also directed to certain of the organophosphite-promoted cobalt and ruthenium-cobalt carbonyl catalyst systems per se.

    摘要: Propylene is oxidized directly to allyl acetate in the presence of acetic acid with air or oxygen in the liquid phase under moderate reaction conditions employing a palladium-on-carbon catalyst which has been pre-treated by activating it with propylene at temperatures of greater than about 50.degree. C., preferably from 60.degree. to 150.degree. C., for a period of time sufficient to form a small but perceptible quantity of said activated catalyst, preferably for at least 10 minutes in the substantial absence of oxygen.

    摘要: C.sub.4 olefins comprising cis- and trans-butane-2 and butene-1 may be oxidized to their corresponding mono- and diacetates in the presence of acetic acid and an olefin-activated palladium catalyst under mild conditions. With this catalyst, and depending in part upon the solvent employed, as well as other operating conditions, the formation of linear allylic 1-acetates over the corresponding branched compounds can be favored in order to increase the yield of the corresponding linear 1,4-diacetates. The latter, in turn, may then be converted, for example, to butanediol by known hydrogenation methods.In a similar manner, isobutylene may be converted to a dialcohol.
