Abstract: A process is provided for the enhanced recovery of oil with steam in reservoirs containing high concentrations of dissolved salts, wherein certain diaryl sulfonated surfactants are employed in conjunction with the steam which posses high tolerance for said salts. These surfactants are comprised of compositions having (1) two aromatic rings in their nucleus, such as diphenyl, diarylalkane, or naphthalene groups; (2) at least one alkyl group having 18 or more carbon atoms; and a second alkyl group having from 1-4 carbon atoms; and (3) two functional groups comprising at least one and preferably two sulfonate groups, although one of the sulfonate groups may be replaced with a carboxyl or hydroxyl groups. At least about 65% of the diaromatic compounds should contain two functional groups, preferably sulfonates, with the remainder comprising a monofunctional-substituted compound containing either a sulfonate group, a carboxylate group, or an hydroxyl group.

Abstract: 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.

Abstract: Alkylaromatic sulfonates, and particularly dialkylaromatic sulfonates, useful as surfactants in steam recovery methods for enhancing oil recovery from subterranean formations, have been found to comprise mixtures of meta- and para-isomers of the same obtained by alkylating alkylaromatics, where the alkyl group has from 1 to 4 carbon atoms, with a C.sub.14-30 olefin. It has been found that when the ratio of para-isomer to meta-isomer is increased in this mixture, a significantly more hydrolytically, thermally stable surfactant under steam recovery operating conditions is obtained.

Abstract: 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.
