Abstract: The invention relates to a method for reacting organic compounds with a hydrogen-peroxide solution. The method is characterised in that each concentration of dissolved anions and cations in the hydrogen-peroxide solution which is used, is less than 100 ppm. The invention also relates to methods for reducing the salt concentration in hydrogen-peroxide solutions, to the use of hydrogen-peroxide solutions produced by this method for reacting an organic compound and to an integrated method for producing a hydrogen-peroxide solution, based on a conventional method using anthraquinone, containing one or more stages for reducing the salt concentration.

Abstract: The invention relates to a moulded body comprising an inert support and at least one porous oxidic material applied to said support. The inventive moulded body is obtained by applying a mixture containing the at least one porous oxidic material and at least one metal acid ester or a hydrolyzate thereof or a combination of metal acid esters and hydrolyzate thereof to the inert support.

Abstract: A process for regenerating a zeolite catalyst comprises the following stages: (I) Heating a partially or completely deactivated catalyst to 250-600° C. in an atmosphere which contains less than 2% by volume of oxygen, (II) treating the catalyst at from 250 to 800° C., preferably from 350 to 600° C., with a gas stream which contains from 0.1 to 4% by volume of an oxygen-donating substance or of oxygen or of a mixture of two or more thereof, and (III) treating the catalyst at from 250 to 800° C., preferably from 350 to 600° C., with a gas stream which contains from more than 4 to 100% by volume of an oxygen-donating substance or of oxygen or of a mixture of two or more thereof.
