    摘要: The present invention relates to a process for the production of a titanium silicalite shaped body by: (a) forming a formable composition containing titanium silicalite, a binder and a pasting agent, so that the Curd curve of the formable composition has a plateau value in the range from 20 to 90 mm; (b) shaping the composition of step (a) to form a green body; (c) optionally drying and (d) calcining the green body, to a titanium silicalite shaped body obtainable by that process, and to the use of such titanium silicalite shaped bodies in the epoxidation of olefins or the ammoximation of ketones.

    摘要: Ternary, pyrogenically prepared, crystalline metal mixed oxide powder having the components titanium and silicon and a third component chosen from the group comprising aluminium, zirconium, zinc, tin, magnesium, yttrium, vanadium, tungsten, tantalum, cerium or boron. It is prepared by a procedure in which a vaporizable or atomizable silicon and titanium compound and a vaporizable or atomizable compound of a third mixed oxide component are mixed with hydrogen and primary air and the gas mixture is burned into a reaction chamber, and the powder formed is separated off from the gaseous reaction products. It can be employed in sunscreen formulations.

    摘要: Brushable cosmetic preparation having a creamy or paste-like consistency, containing 50 to 95 wt. % of water, hydrophobed silicon dioxide powder, at least one cosmetically relevant active ingredient or auxiliary substance that is water-soluble or is dispersible or emulsifiable in an aqueous medium, and a viscosity regulator. It is produced by adding at least one cosmetically relevant active ingredient and/or auxiliary substance and optionally at least one pigment in water to a solution or dispersion adding hydrophobed silicon powder in portions or continuously whilst mixing and continuing mixing until the mixture, which is originally in powder form after addition of hydrophobed silicon dioxide powder, takes on a pasty consistency, and then adding a viscosity regulator and optionally at least one oil body, optionally before, together with or after addition of the viscosity regulator, with mixing. It can be used in pastes, creams, gels, pencils, foams, emulsions, dispersions, roll-ons, lotions.

    摘要: A method for epoxidation of olefins with 2 to 6 C atoms, especially propene, with hydrogen peroxide in the gas phase at a temperature below 250° C. The reaction is carried out by bringing a gas mixture containing the olefin, hydrogen peroxide and water into contact with the catalyst from the series of compounds of an element of the 4th to the 6th subgroup of the periodic table or of arsenic or selenium and molecular sieves in the absence of a liquid phase. Titanium-containing molecular sleeves are preferred catalysts.
