Abstract: An inert, water-immiscible inert organic liquid having gas transport properties, water and a suitable emulsifying agent are formed into a stable gel by emulsifying a mixture of the same, concentrating the emulsion to form a gel phase and a liquid phase and separating the two phases. The resulting gel can be used as an ointment or cosmetic for skin irritations or wounds, or as a coating in industrial applications where extended contact of a surface with a gas, such as oxygen, is desired. Fluorocarbons or low viscosity silicone oils are suitable organic liquid components of the gels.

Abstract: In the process of preparing esters of cinnamic acid by reacting a styrene compound with carbon monoxide, oxygen, and an aliphatic alcohol in the presence of a catalyst, the improvement comprising using less than a stoichiometric amount of a dehydrating agent to increase the yield and selectivity of the reaction products.

Abstract: The invention discloses an improvement to the selective production of dialkyl succinates by the known process of oxidative carbonylation of an olefin with carbon monoxide, oxygen, and an alkyl alochol in the presence of a catalyst wherein the improvement comprises using a sulfone as the reaction solvent. The use of a sulfone, of which sulfolane is a preferred example, results in fast reaction rates and high selectivity to dialkyl succinates even in the absence of a dehydrating agent.

Abstract: The process for the acid-catalyzed reaction of acetone with methanol to form 2,2-dimethoxypropane may be significantly improved if a stoichiometric ratio of methanol/acetone is employed in the initial reaction.Of particular advantage is the use of stoichiometric amounts of reactants in order to (1) avoid the expense of using an excess of either reactant, and (2) facilitate the removal of the 2,2-dimethoxypropane as an azeotrope with the methanol, thereby avoiding costly and complex product recovery methods.

Abstract: Fluorocarbons are purified and toxicity substantially reduced by contact with a substantially dry, strongly basic and strongly nucleophilic alkali or alkaline earth metal compound, and separating the decomposition products which form.

Abstract: In order to reduce the economic impact of segregated ballast requirements for tanker vessels, heavy ballast, for example concrete, is placed in the segregated ballast tanks in amount to occupy 30 to 50% of the free volume of the tank. The rest of the tank may be filled with water ballast. The use of heavy ballast provides a total ballast weight equal to that obtainable with a greater number of tanks filled with water ballast only, thus increasing the available cargo space.

Abstract: There is provided herein a process and composition for the enhanced recovery of oil from subterranean formations comprising injecting in combination with steam a composition comprising (a) an anionic surfactant and (b) a hydrotrope.

Abstract: A method of preparing esters of cinnamic acid comprising catalytically reacting a styrene compound with carbon monoxide, oxygen, and an aliphatic alcohol. The catalyst is essentially a combination of a palladium (II) compound and a copper salt. A catalytic amount of a dehydrating agent may be present to increase the selectivity of the reaction.

Abstract: Propylene is oxidized directly to allyl acetate in the presence of acetic acid air or oxygen in the liquid phase under moderate reaction conditions employing a palladium-on-carbon catalyst which has been pre-treated be 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.

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.
