    Abstract: The invention relates to a method for catalytically hydrating an organic compound, especially an unstable organic compound, in the presence of a supported catalyst that is provided with a coating that contains ruthenium as the active metal and a total of 0.01 to 30 % by weight of active metals. The aim of the invention is to increase stereoselectivity and catalyst service life. To this end, a supported catalyst is used whose oxide-, carbide-, nitride- or silicate-containing support material, prior to being charged with at least one active metal, has a BET(N2) surface of less than 10 m /g, preferably 0.1 to 5 m /g, with the exception of diatomaceous earth with a BET(N2) surface of greater 2 m /g, and whose ruthenium content constitutes at least 50 % by weight, preferably at least 99 % by weight, of the active metals. The invention further relates to the aforementioned supported catalysts. The method and catalysts according to the invention are especially suitable for hydrating polyfunctional compounds such as hydroxycarbonyl compounds and aromatic amines.

    Abstract: Catalytic epoxidation of olefins with hydrogen peroxide uses a continuous flow reaction system. The reaction mixture is passed through a fixed catalyst bed within a reactor equipped with cooling device, while maintaining a temperature profile within the reactor so that the cooling medium temperature of the cooling device is at least 40[deg]C and the maximum temperature within the catalyst bed is 60[deg]C.

    Abstract: In carrying out the hydrogenation stage of the anthraquinone process for the preparation of hydrogen peroxide in a hydrogenation reactor on a fixed bed catalyst of a particulate catalyst, the service life of the catalyst is increased in that the working solution comprising the reaction carrier and a gas phase comprising hydrogen, are passed through the hydrogenation reactor from the bottom upwards. The empty tube speed of the working solution is 0.05 to 100 m/h, preferably 10 to 50 m/h.
