A method for separating electrolyte-containing water from an organic phase by means of permeation on a hydrophobic separating means. The permeated organic solution is substantially depleted in water and the retained water is enriched with electrolytes.

Method for separating an organic phase from an electrolyte-containing aqueous and organic phase

The invention relates to a structured surface with ultraphobic properties. Said surface as a surface topography in which the value of the integral of a function S: S(log f)=a(f)&#xb7;f, which gives a relationship between the spatial frequencies f of the individual Fourier components and their amplitudes a(f) is at least 0.5 between the integration limits log (f/&#x3bc;m)=&#x2212;3 and log (f/&#x3bc;m)=3. The surface consists of a hydrophobic or oleophobic material or is coated with a hydrophobic or oleophobic material.

Ultraphobic surface

The invention is directed towards a process for the epoxidation of olefins, using molecular oxygen and hydrogen, characterized in that, as catalyst, a compound comprising gold, preferably in nanometer size, on a support material, in which the support material is comprised of Scandium, Yttrium, Lanthanide, Zirconium, Hafnium, Vanadium, Niobium, Tantalum, Chromium, Molybdenum and/or Tungsten and is essentially free of titanium is applied, and a compound comprising gold, preferably in nanometer size, on a support material, in which the support material is comprised of Scandium, Yttrium, Lanthanide, Zirconium, Hafnium, Vanadium, Niobium, Tantalum, Chromium, Molybdenum and/or Tungsten and is essentially free of titanium, a process for the preparation of said compounds and a method of catalyzing a chemical reaction through conducting said chemical reaction in the presence of said compound.

The invention relates to a method for producing an ultraphobic surface on aluminium as the supporting material and to the resulting surface and its use. According to said method, the surface of an aluminium support is anodized, especially by anodic oxidation, and/or electrochemically pickled in an acid solution with an alternating voltage, treated in hot water or water vapor at a temperature of 50 to 100&deg; C., optionally coated with an adhesion promoter layer and then provided with a hydrophobic or especially oleophobic coating.

The present invention relates to a composite particle containing a solid inorganic or organic colorless support material and adherent to it an inorganic and/or organic pigment particle, wherein the pigment particle has an average particle size of 1 nm to 100 nm, comprises at least one primary pigment particle and the minimum average distance between two pigment particles is at least one quarter of the diameter of the primary pigment particle, whereby the modified inorganic and organic pigments, depending on the pigment material, can be used as IR light absorbers or as color-imparting agents and give rise to a negligible haze in the matrix.

Composite particles

This invention relates to electrochromic devices that are protected against UV light by nanoparticles.
