Abstract: Method for the production of hydroperoxides of hydrocarbons having no aliphatic or cycloaliphatic tertiary carbon atoms wherein such hydrocarbons are oxidized in the liquid phase with molecular oxygen in the presence of a tertiary alcohol and a tertiary hydroperoxide. This method gives high hydroperoxide selectivities at high conversion levels and at high conversion rates.

Abstract: Apparatus for generating electrical stimulation pulses in the absence of naturally occurring "R" heart waves includes a free running multivibrator for generating pulses at the desired heart stimulation rate and an output amplifier and voltage multiplier for amplifying the generated pulses for application to the heart. A plural stage filter-amplifier amplifies any naturally occurring "R" waves to trigger a normally nonconducting multivibrator to activate disabling transistors, in turn, which discharge the timing capacitors of the free running multivibrator.The apparatus can be used with either a chemical or nuclear battery or other load dependent low voltage source.

Abstract: A process for the manufacture of urethanes and the optional co-production of amines by reacting at elevated temperatures and pressures an organic compound containing at least one hydroxyl group with carbon monoxide and a nitrogenous organic compound containing at least one non-cyclic group, in which a nitrogen atom is directly attached to a single carbon atom and is also attached through a double bond to an oxygen or another nitrogen atom, in the presence of an active amount of a catalyst selected from the group consisting of selenium, sulfur, selenium compounds, tellurium compounds, sulfur compounds and mixtures thereof and a base and/or water.

Abstract: Cyclohexene is converted to 3,6-diacyloxycyclohexene by reaction with a C.sub.2 to C.sub.6 aliphatic acyclic saturated carboxylic acid and an organic hydroperoxide in the presence of a copper catalyst. The diacyloxycyclohexene is hydrolyzed to the corresponding dihydroxycyclohexene and dehydrogenated to hydroquinone. For example, with acetic acid the cyclohexene is converted to the 3,6-diacetoxycyclohexene which after hydrolysis and dehydrogenation gives hydroquinone.

Abstract: Method for the production of hydroperoxides of hydrocarbon having no aliphatic or cycloaliphatic tertiary carbon atoms, wherein such hydrocarbons are oxidized in the liquid phase with molecular oxygen in the presence of a stabilizing agent. This method gives high hydroperoxide selectivities at high conversion levels.

Abstract: The present invention provides oil-soluble, polymeric surface-active agents which are polyimide-amine salts of styrene-maleic anhydride copolymers having pendant tertiary amine groups containing a salt-forming tertiary nitrogen atom neutralized to the extent of at least about 75 percent with mono-carboxylic acids for instance having an aliphatic chain of at least about 8 carbon atoms. The salts of this invention exhibit the property of lowering the surface tension at oil-water interfaces. The polyimide-amine salts can also contain mixed imides resulting from the reaction of dialkylaminoalkylamines and monoalkyl amines or mixed imide-amides resulting from the reaction of dialkylaminoalkylamines and dialkylamines. This invention also provides oil compositions containing mineral oil and the oil-soluble, polymeric surface-active polyimide-amine salts, with or without water.

Abstract: Compounds of the formula ##EQU1## WHEREIN R is a hydrocarbyl radical selected from the group consisting of alkyl, aralkyl and cycloalkyl having from 3 to 12 carbon atoms and n is an integer from 1 to 9 are prepared by reacting a 1,1-bis (hydrocarbyl peroxy) cycloalkane with cycloaliphatic ketones in the presence of a molybdenum containing catalyst. The 1,1-bis (hydrocarbyl peroxy) cycloalkane can be prepared in situ from an organic hydroperoxide and a cycloalkanone. The compounds have utility as solvents and certain specific members of the class have utility as intermediates to adipic acid by further oxidation or as an intermediate to 2-t-butoxyphenol by known dehydrogenation methods.
