Abstract: A gasoline blending stock is produced by the simultaneous reaction of a hydrocarbon feed containing at least one tertiary olefin, at least one aliphatic alcohol, and water over a suitable catalyst. In a typical embodiment, a mixed C.sub.4 stream containing isobutylene is reacted with aqueous ethanol to form a mixture of ethyl tertiary butyl ether and tertiary butanol, with minimal formation of secondary alcohols from any normal butenes present in the hydrocarbon feed.

Abstract: A method of improving in the combustibility of gasoline by injecting oxygen gas into gasoline in the stationary or flowing state under a magnetic field. The gasoline treated by the method has an ability to prolong the running time of an internal combustion engine 3% to 4% longer under the same conditions than the untreated gasoline.

Abstract: Specified copolymers of tert-butylstyrene are dissolved in a liquid aliphatic hydrocarbon fuel, especially an aircraft fuel, by the steps of (i) blending the finely-divided copolymer with a non-solvent hydroxylic liquid miscible with the fuel, (ii) mixing the blend into the fuel so as to give a copolymer concentration of 01.-1% by weight, and (iii) dissolving in the fuel so treated an amino compound in an amount of 0.01-0.6 mole per 100 g of copolymer present. The copolymers thus dissolved impart to the fuel a resistance towards mist formation when the fuel is subjected to conditions of shock.

Abstract: This invention relates to .alpha.-olefin-acrylonitrile copolymers and uses thereof, particularly as antistatic agents in organic liquids such as hydrocarbon fuels.

Abstract: A lubricant especially adapted to meet the requirements of firearms, the lubricant being constituted by a dispersion of microfine PTFE particles in an oil carrier diluted with a major amount of synthetic lubricant having a low viscosity and a high viscosity index, whereby the resultant hybrid lubricant not only reduces wear and friction, but also affords a protective coating for the treated metal surfaces which resists the adhesion thereto of grime, powder, lead and all other contaminants that otherwise make it necessary to frequently clean the weapon to maintain it in proper working order.

Abstract: Mine run coal is pulverized and the extended surfaces of the coal particles are rendered hydrophobic and oilophilic by a chemical bonding and graft polymerization reaction with a water insoluble organic polymerizable monomer under peroxidation influence in a predominantly water reaction medium.The mineral ash present in the coal and particularly the iron pyrites remains hydrophilic and is separated from the polymeric organic surface bonded coal product in a water washing step wherein the washed coal floats on and is recovered from the water phase and the ash is removed with the separated wash water in a critical wash step.Excess water is removed from the beneficiated hydrophobic surface-altered coal product mechanically. The hydrophobic and oilophilic organic polymeric surface bonded coating about the coal particles is fortified by inclusion of additional unbound free fatty acids by further small additions thereof.

Abstract: An oxygenated hydrocarbon based fuel for use in internal combustion engines is composed by volume of alcohol (40-80%), ketone (0-30%) ether (15-40%), a dimethyl siloxane (0.01-1.0%) a surfactant (0.25-1.0%) and a fuel-soluble corrosion inhibitor (0.02-0.1%). The resulting fuel has excellent storage life and performance characteristics superior to gasoline.
