Abstract: A method for separating volatile flavorings from alcoholic liquids by extraction with a compressed C2-C4 hydrocarbon.

Abstract: Process for the extraction of substances from at least one silane-modified oxidic or silicatic filler, wherein at least one gas compressed by means of pressure and/or temperature is employed as the extraction agent and the compressed gas is led in the radial direction through the filler in the pressure container and/or the substances extracted from the silane-modified filler are removed from the compressed gas with a suitable sorbent. A device for carrying out the process is furthermore described, wherein this comprises at least one pressure container having at least one internal container, sieve or insert for accommodation of the fillers which is permeable to gas and at least one gas feed and gas removal in the bulk bed of filler, and has a radially designed gas feed or gas removal from the bulk bed of filler.

Abstract: Silane-modified oxidic or siliceous filler with a bead fraction below 75 ?m of less than 15 wt. % and a median particle size distribution between of 150 to 500 ?m, which is produced by the reaction of at least one microbeaded or microgranular, oxidic or siliceous filler in a compressed gas with at least one silane. The silane-modified oxidic or siliceous fillers are used in rubber compounds.

Abstract: Disclosed is a method for the selective separation of volatile flavorings from monophase, (semi)liquid starting materials having a fat content and/or oil content of =20 percent by weight, said method being preferably carried out at temperatures of =70 ° C. and at pressures of <50 MPa, especially by using compressed ethane, propane, butane, or any mixtures thereof. The starting materials can be pastes and purees having a fluid content of =10 percent by weight and water-containing and/or alcohol-containing liquids, especially juices and waters obtained during the production of juice, as well as alcoholic beverages and hard liquors. The inventive method makes it possible to obtain particularly separated natural, nature-identical, and/or artificial flavorings of high sensory qualities while undesired flavorings can be removed from the starting materials, i.e. said starting materials can be deodorized.

Abstract: The present invention provides a process for the removal of ethanol from drinks produced by fermentation by direct extraction of the ethanol in countercurrent with compressed carbon dioxide as extraction agent and separation of the extracted water-ethanol mixture from the extraction agent by lowering the density of the compressed gas, wherein, after the lowering of the density, the carbon dioxide is regenerated by a treatment with water and then returned to the extraction step.
