Abstract: A fuel composition comprising carbon black and a combustible liquid such as lower alkyl alcohols having 1 to 4 carbon atoms or liquid hydrocarbons is provided. The composition is formed by adding a sufficient amount of carbon black to the combustible liquid without thereby causing an increase in the volume of the mixture by more than about five percent (5%).

Abstract: Nitrogen-containing compositions made by condensing a nitro phenol with an organic amino compound having at least one hydrogen atom directly bonded to a nitrogen or oxygen atom are useful as additives for lubricants and fuels. A specific embodiment comprises compositions made by reacting nitro phenols having hydrocarbyl substituents of up to 750 aliphatic carbon atoms with alkylene polyamines.

Abstract: A gasoline and petroleum fuel supplement formed of a combination of ingredients including methyl alcohol, xylene, ethyl alcohol, and at least one alkali metal hydroxide. These ingredients may be added in various ratios to gasoline and/or to treated water for use as fuel supplement in an internal combustion engine.

Abstract: A catalyst containing alkali metal, chromium, iron, lead, phosphorus and oxygen, and a process for the preparation of unsaturated lower aliphatic acids and esters of such acids by catalytic oxidative dehydrogenation of the corresponding saturated acids and esters using the catalyst.

Abstract: This invention relates to stable, fluid magnesium-containing dispersions and the preparations thereof by the high temperature decomposition of MgCO.sub.3 to MgO in a dispersant-containing fluid.

Abstract: A method for supressing carburetor deposit formation of motor fuels containing untreated cat cracked gasoline by blending adsorbent-treated cat cracked gasoline into the motor fuel. Up to about 50 percent by weight of the total composition is adsorbent-treated cat cracked gasoline, but preferably from about 5 to about 25 percent by weight of the total composition is adsorbent-treated cat cracked gasoline. In a preferred embodiment a standard reference fuel capable of providing a predetermined level of carburetor deposit formation is provided by the addition of either adsorbent-treated cat cracked gasoline, untreated cat cracked gasoline, or aromatic amines to a base fuel.

Abstract: An improved method for the recovery of para-aminophenol from crude solutions thereof such as obtained by the catalytic hydrogenation of nitrobenzene in an aqueous acid reaction medium. The method comprises neutralizing the cold, acidic solution containing the crude para-aminophenol whereby a very fine fluffy para-aminophenol precipitates. When an aromatic amine selected from the group consisting of aniline, mixed toluidines, ortho-toluidine, mixed xylidines, and mixtures thereof is admixed therewith an upper layer containing the para-aminophenol suspended in the aromatic amine forms when allowed to settle. A clear lower layer containing about 70 to 90% of the ammonium sulfate solution is separated and discarded. The upper layer which contains the aromatic amine and the para-aminophenol can be used as a source of para-aminophenol for producing para-aminophenol derivatives such as diaryl para-phenylenediamines.

Abstract: Pigments that are suitable for coloring clear plastics are prepared by grinding together crude copper phthalocyanine and crude cobalt phthalocyanine in the presence of a conventional grinding aid and a conventional conditioning agent.

Abstract: Apparatus and method for producing a fuel comprised of oil and water in which a mixture of oil and water is constituted as an emulsion by exposure to agitation effective to cause cavitation within the mixture.

Abstract: A 1,1-dichloro-4-methyl-3-hydroxy-pent-1-ene and a process for its production.

Abstract: Extraction of purified plant anthocyanin colors particularly from dark grapes by treating impure materials to insure discrete monomeric anthocyanin molecules in solution and then passing the solution through ultrafiltration membranes to retain soluble and/or cloudy macromolecular, e.g., colloidal, impurities upstream that produce, an aging, haze and sediments, and pass the monomeric anthocyanins downstream for further concentration as liquid or powder to give a stable color concentrate that can be used as a color additive. For example, fruit solids may be treated with sulfur dioxide solutions to ionize, decolor and insure the monomeric state of the pigment molecules (change from anthocyanins to chromon 2-and 4-sulfonates), ultrafiltering the solution to pass the anthocyanins downstream while retaining upstream the macromolecular components such as pectins, tannins, proteins, complexes thereof, etc.

Abstract: Described are dual purpose cutting oils which serve as heavy duty cutting oils and machine lubricants in automatic screw machines. The oils comprise a base oil, a combination of extreme pressure agents comprising primarily a di-tertiary alkyl polysulfide, a chlorinated paraffin, and a copper corrosion inhibitor comprising a sulfur scavenger such as a 2,5-bis(n-alkyldithio)thiadiazole.

Abstract: Oil-soluble combinations of (A) ethylene polymer or copolymer, (B) normal paraffinic wax composed of normal hydrocarbons whose average molecular weight is within the range of from 300 to 650, and (C) nitrogen compounds, such as amides, amine salts and ammonium salts, of carboxylic acids or anhydrides, are useful in improving the cold flow properties of distillate hydrocarbon fuel oils. Preferably, the wax contains n-paraffins ranging from C.sub.23 to C.sub.37 inclusive. If desired, the combination can be usefully stabilized by the addition of one or more compatibility additives, i.e. a polymer having alkyl side chains of 6 to 30 carbon atoms and derived from carboxylic acid esters and/or olefins or C.sub.8 -C.sub.18 alkanol, e.g. tridecyl alcohol or mixtures of said polymer and alkanol.
