Abstract: A process for treating thiosulfate containing liquors such as coke oven gas scrubbing liquors by first adding acid, preferably sulfuric acid, to convert thiosulfate to elemental sulfur and bisulfite, separating and removing the elemental sulfur, and subjecting the remaining liquor to wet oxidation.

Abstract: A continuous process for wet oxidation of aqueous liquor containing combustible matter using oxygen or oxygen enriched gas. An inert diluent gas is injected into the aqueous liquor or reactor off-gas such that oxygen in the gas phase is diluted by the sum of generated water vapor, produced carbon dioxide and injected inert gas to a concentration less than required for spontaneous combustion at every location in the system having surfaces not continually exposed to a continuous liquid water phase.

Abstract: 3.alpha.-Benzoylamino-2.beta.-hydroxy-nortropanes substituted in the 8-position by an alkoxycarbonyl or alkanoyl group, useful as analgesics, are prepared by reacting the corresponding 2.beta.,3.beta.-epoxy-nortropane with benzylamine in the presence of phenol.

Abstract: A novel antiviral agent, tert-butyl (3,4-dibenzyloxy)styryl ketone, is described.

Abstract: A process and apparatus for treating thiosulfate containing liquors such as coke oven gas scrubbing liquors in two stages of wet oxidation with intermediate removal of elemental sulfur. Mild oxidation conditions in the first stage results in conversion of thiosulfate sulfur to elemental sulfur, which is removed prior to second stage wet oxidation of the liquors to substantially reduce the liquor oxygen demand.

Abstract: An apparatus for introducing powdered solids into a liquid stream at a controlled rate to form a slurry. Solids are metered to an eductor where they are educted into the liquid stream. An automatic cycle timer-controller purges eductor, hopper and piping of residual solids before solids flow is initiated, and following solids flow. Pressure sensors detect low water pressure and/or plugging, shutting off liquid and solids flow.

Abstract: An improvement in the wet oxidation of caustic waste liquors wherein carbon dioxide produced in the wet oxidation is recycled to raw caustic waste to neutralize the latter, thereby reducing the corrosive nature of the waste.

Abstract: The compounds of the formulas ##STR1## where R and R' are lower-alkyl possess glucocorticoid activity, and are prepared by reacting the compound of the formula ##STR2## with the appropriate dienophile.

Abstract: The compounds of formula ##STR1## where R is hydrogen or fluorine possess glucocorticoid activity, and are prepared by reacting a compound of the formula ##STR2## with 1,2,3-indantrione.

Abstract: 3.alpha.-Benzylamino-2.beta.-hydroxy-nortropanes substituted in the 8-position by an alkoxycarbonyl or alkanoyl group, useful as analgesics, are prepared by reacting the corresponding 2.beta.,3.beta.-epoxy-nortropane with enzylamine in the presence of phenol.

Abstract: A process for enhanced oil recovery by gas injection into oil-bearing formations which comprises wet oxidizing combustible carbonaceous materials with oxygen, air or a mixture of oxygen and air to obtain a gas comprising a mixture of water vapor and carbon dioxide (and nitrogen in the event air is used), substantially free of oxides of sulfur and nitrogen; injecting said gaseous mixture into an oil-bearing formation to produce a mixture of oil and water; extracting said mixture of oil and water from the oil-bearing formation; separating the water from the latter mixture; and recycling the water to the wet oxidation reactor. Residual oil in the recycled water provides additional fuel for the wet oxidation reaction, and at the same time the need for costly water treatment is eliminated.

Abstract: A process for dewatering slimes produced in mining and mineral processing operations whereby wet oxidation at 150.degree.-320.degree. C. renders the solids rapidly settleable. Sufficient oxygen is supplied to meet or exceed oxygen demand. Inorganic solids in the oxidized product are separated and optionally further dewatered to a friable solid. Clarified water is recycled to the mining, mineral processing or other operations, or treated further, or discharged to the environment. Steam resulting from the wet oxidation is utilized in the mining or mineral processing operations.

Abstract: The compound of the formula ##STR1## possesses glucocorticoid activity, and is prepared by reacting the compound of the formula ##STR2## with 2-vinylpyridine.

Abstract: Compounds of tropane (8-azabicyclo[3.2.1]octane) series having an aromatic substituent in the 2-position and a carboalkoxy group in the 3-position are prepared by reacting a tropane-3-carboxylate having a double bond in the 2,3-position with an aryl Grignard reagent. Transformations of the substituent on nitrogen are subsequently effected. Compounds where the 3-carboalkoxy group is in the exo configuration possess hypoglycemic activity, and those where the 3-carboalkoxy group is in the endo configuration possess narcotic antagonist activity.

Abstract: Aryl substituted diketones and keto-esters, useful as antiviral agents and insecticides, are prepared by reacting an arylalkyl or arylalkenyl iodide with a metal salt of the appropriate diketone or keto-ester.

Abstract: 4-(Arylaliphatic)isoxazoles, having antiviral activity, are prepared by reacting with hydroxylamine a diketone of the formula Ar-Y-CH(CO-R).sub.2, wherein Ar is substituted phenyl, Y is (CH.sub.2).sub.n or O(CH.sub.2).sub.n, and R is lower-alkyl.

Abstract: Disinfection of aqueous media contaminated with microorganisms is effected by contacting said media with a gas phase in which a plasma is generated by focused laser radiation. Similarly, wastewaters containing organic susbstances are purified by contacting them with an oxygen-containing gas phase in which a plasma is generated by focused laser radiation which promotes oxidation of the organic substances to innocuous products.

Abstract: 4-(Aryloxyalkyl)pyrazoles of the formula ##STR1## useful as antiviral agents, are prepared by reacting the corresponding diketones of the formula Ar--O--Alk--CH(COR')COR" with hydrazine or a substituted hydrazine H.sub.2 NNHR.

Abstract: Aminosulfonyl-substituted aryloxyalkyl diketones, useful as antiviral agents, are prepared by reacting a haloalkyl diketone with an alkali metal salt of a hydroxybenzenesulfonamide.

Abstract: 9-Phenyl(or benzyl)acridines, 9-phenyl(or benzyl)-9-acridinols and acridinium compounds, useful as trypanosomacidal and antibacterial agents, are prepared from aminoalkoxy substituted 9-acridinones via reaction with the appropriate Grignard reagents or aryllithium. The intermediate aminoalkoxy substituted 9-acridinones, prepared from the corresponding halo or hydroxy substituted 9-acridinones, are useful as antiviral agents.
