Abstract: The hydroperoxides of diisopropylbenzene are prepared by the oxidation of diisopropylbenzene with molecular oxygen in the presence of a minute amount of solid barium oxide.

Abstract: An alpha-olefin oligomer synthetic lubricant having an improved viscosity-volatility relationship is prepared from an alpha-olefin such as 1-decene.

Abstract: A process for producing a novel composition of matter which comprises oxidizing a hydrocarbon oil with aqueous nitric acid, separating from the resulting oxidation product an aqueous phase and an oxidized hydrocarbon phase as the novel composition of matter. The novel composition of matter can itself be used as a fuel or it can be a component of a novel fuel composition.

Abstract: Indene is separated from close boiling, olefinically unsaturated alkylaromatic compounds by extractive distillation. For example, indene is separated from trans-.beta.-methylstyrene, and from 2-, 3- and 4-methylstyrene by extractive distillation using 1-methyl-2-pyrrolidone as the extracting agent.

Abstract: Diesel fuel compositions which contain minor amounts of azides having the formula:X=N.sup.+ =N.sup.-where X is selected from the group consisting of ##STR1## where R and R' can be the same or different and are selected from the group consisting of hydrogen; alkyl straight- and branched chain hydrocarbons having from 1 to 8 carbon atoms; alkoxy groups having from 1 to 8 carbon atoms; aryl; aryloxy; nitro; hydroxy; halo; amino (except ortho to the azido); alkylamino; acyl groups having from 2 to 8 carbon atoms; alkylamido; and carbalkoxy. The minor amount of the azides in part improved cetane numbers (low ignition delay) to the diesel fuel.

Abstract: A catalyst residue containing osmium catalyst having a substantial component with a valency state less than +5 is regenerated to a valency state greater than +5 by contacting the residue with an organic hydroperoxide at a pH greater than 7 and the regenerated catalyst residue is recycled to a hydroxylation reactor containing ethylene or propylene, a polar organic solvent, an aqueous solution of cesium, rubidium, potassium or tetraalkylammonium hydroxide and an organic hydroperoxide.

Abstract: Process for generating energy in a furnace or a combustion engine which comprises burning in said furnace or said combustion engine a mixture of polycyclic, polycarboxylic acids obtained by oxidizing coal with aqueous nitric acid, separating from the resulting product an aqueous phase and a solid phase and then extracting the solid phase with a solvent to recover said mixture.

Abstract: An integrated in situ combustion process for recovering subterranean liquid and solid carbonaceous deposits in which the resulting flue gas of low heating value is combusted at substoichiometric conditions over two different oxidation catalysts in two combustion zones in series and is expanded in a gas turbine which drives the air compressor for injecting the combustion air into the underground carbonaceous deposit. One of the oxidation catalysts comprising platinum and at least one metal cocatalyst selected from Groups IIA and VIIB, Group VIII up through atomic No. 45, the lanthanides, chromium, zinc, silver, tin and antimony is provided to reduce the carbon monoxide in the combusted flue gas.

Abstract: A suspension containing coal, hydrocarbon oil, water and the product resulting from the reaction of (1) polycyclic, polycarboxylic acids obtained as a result of the oxidation of coal with (2) a base. The process for preparing such suspension is also claimed.

Abstract: A catalyst that is highly active in the oligomerization of lower olefins such as ethylene is produced by contacting (a) a refractory metal oxide/silica support, such as alumina/silica wherein the silica content of the support is from about 2 to about 95 weight percent and the metal oxide content of the support is from about 5 to about 98 percent with (b) a solution of a basic metal and then (c) contacting the resulting metal modified support with a tris(cyclopentadienyl)trinickel dicarbonyl.

Abstract: A catalyst that is highly active at low operating temperatures and pressures in the oligomerization of lower olefins such as ethylene is produced by contacting (a) a refractory metal oxide/silica support such as alumina/silica wherein the silica content of the support is from about 2 to about 95 weight percent and the metal oxide content of the support is from about 5 to about 98 percent with (b) a tris(cyclopentadienyl)trinickel dicarbonyl. When used to oligomerize ethylene, these catalysts are characterized by a relatively high reaction rate at moderate temperatures and pressures. Their use permits the production of relatively high proportions of desirable trimer, tetramer, pentamer, and higher olefinic products.
