摘要: The invention refers to a process for producing an anticorrosive coating in which a surface to be treated is brought into contact with an aqueous treatment solution containing chromium(III) ions and at least one phosphate compound and an organosol. The corrosive protection of metal surfaces, in particular those containing zinc and zinciferous surfaces with conversion layers is improved. The decorative and functional properties of the surfaces are retained or improved. In addition, the well-known problems associated with the use of compounds containing chromium(VI) or with multi-stage processes are avoided in which a passivation layer containing chromium ions and a sealing are applied one after the other.

摘要: In a process for the preparation of alkylaromatic compounds by reacting C3-30-olefins, or alcohols from which C3-30-olefins are formed under the reaction conditions, with an aromatic hydrocarbon in the presence of an alkylation catalyst, the reaction is carried out in a reactor cascade of at least two reactors, where each of the reactors comprises the alkylation catalyst, at least 80% of the aromatic hydrocarbon are fed into the first reactor of the reactor cascade, and at least 40% of the olefins are intermediately fed in after the first reactor.

摘要: An agent for the production of anti-corrosion layers on metal surfaces is produced by producing an aqueous solution, which contains at least oxo-cations and halogen complex anions, and forming nanoparticles in the solution in situ by physical and/or chemical treatment of the solution. The oxo-cations are selected from MnO3+, VO3+, VO2+, WO22+, MoO22+, TiO2+, ZrO2+ and mixtures thereof, and the halogen complex anions have the structure MXab−, wherein M is selected from B, Ti, Zr, Si, Al, X is selected from F, Cl, Br, I, a is an integer of between 3 and 6 and b is an integer of between 1 and 4. The nanoparticles have a mean particle diameter of
