METHOD OF OBTAINING HYDROGEN PEROXIDE THROUGH DIRECT SYNTHESIS Russian patent published in 2009 - IPC C01B15/29 C07C27/16 

FIELD: chemistry.

SUBSTANCE: explosive-safe gas mixture, containing hydrogen and oxygen, and a liquid reaction medium, which contains at least one water soluble organic solvent, halide and strong acid, are passed through a fixed bed of catalyst particles in a reactor, deposited on a carrier, or mixture of particles containing and not containing catalyst. The reaction takes place in a reactor made from high-quality steel. The gas mixture passing through the reactor is not in prolonged contact with any part of the steel inner surfaces. The liquid reaction medium is passed through the fixed bed with hourly consumption of 0.3-20 m³ per unit cross sectional area of the reactor. A bubbling reactor column can be used for moving liquid reaction medium from bottom to top such that, a continuous gas phase does not form in it. The obtained organic or aqueous-organic solution of hydrogen peroxide is used for oxidising olefins, aromatic hydrocarbons, carbonyl compounds in the presence of a catalyst, chosen from a group containing silicates of titanium, vanadium, molybdenum and/or tungsten compounds.

EFFECT: prevention of reactor corrosion.
