  • Patent number: 8802606
    Abstract: The instant invention provides a lubricant composition having improved four-ball antiwear properties. The lubricant composition includes a base oil and one or more alkylethercarboxylic acid corrosion inhibitor(s) having the formula: wherein R is a straight or branched chain C6-C18 alkyl group and n is a number of from 0 to 5. The lubricant composition also includes an ashless antiwear additive including phosphorous. The four-ball antiwear properties are reported as an average diameter of wear scars pursuant to ASTM D4172. The average diameter of the wear scars resulting from the lubricant composition are at least 5% smaller than the average diameter of the wear scars resulting from a standard that includes the base oil and the antiwear additive and that is free of the one or more alkylethercarboxylic acid corrosion inhibitor(s).

  • Patent number: 8802748
    Abstract: A graft polymer mixture comprising a grafting base based on brown coal and/or polyphenol is proposed, which has, as a graft component, a copolymer consisting of one or more ethylenically unsaturated monomers different from one another and one or more polyamides different from one another. Typical grafting bases are brown coal, brown coal coke, lignite and brown coal derivatives and tannins. Suitable graft components are in particular vinyl-containing components and styrenes, which may also be present in sulphonated form. Natural polyamides, such as, for example, casein, gelatin and collagen, are suitable polyamide components. These graft polymers having a preferred molar mass Mn>5000 g/mol are suitable as a mixture, in particular in construction chemistry applications, and in the development, exploitation and completion of underground mineral oil and natural gas deposits, and in deep wells, since they have excellent salt and temperature stabilities and are simultaneously water-soluble and/or biodegradable.

  • Patent number: 8801814
    Abstract: A process for partial oxidation of hydrocarbons in a reactor, in which a stream comprising the hydrocarbon and a stream comprising the oxygen are fed to the reactor, wherein both streams fed to the reactor are conducted within the reactor separately through in each case one or more spatially separate lines, these lines having turbulence generators in their interior, owing to which, as a result of the imposed deflection of the flow direction downstream of turbulence generators, a highly turbulent flow field forms, and the streams are then mixed in a mixing zone after exiting from the lines and then converted in a reaction zone.

  • Patent number: 8802027
    Abstract: The present invention generally relates to coating materials, including photoactive coating materials. In some aspects of the invention, a sol-gel is provided that can be formed as a coating on a microfluidic channel. One or more portions of the sol-gel can be reacted to alter its hydrophobicity, in some cases. For instance, in one set of embodiments, a portion of the sol-gel may be exposed to light, such as ultraviolet light, which can be used to induce a chemical reaction in the sol-gel that alters its hydrophobicity. In one set of embodiments, the sol-gel can include a photoinitiator, that upon exposure to light, produces radicals. Optionally, the photoinitiator may be conjugated to a silane or other material within the sol-gel. The radicals so produced may be used to cause a polymerization reaction to occur on the surface of the sol-gel, thus altering the hydrophobicity of the surface. In some cases, various portions may be reacted or left unreacted, e.g.
