The present invention relates to a process for the preparation of hydrogen peroxide from oxygen or oxygen-delivering substances and hydrogen or hydrogen-delivering substances in the presence of at least one catalyst containing a metal-organic framework material, wherein said framework material comprises pores and a metal ion and an at least bidentate organic compound, said bidentate organic compound being coordinately bound to the metal ion. The invention further relates to a novel material consisting of said metal organic framework material wherein the material is brought in contact with at least one additional metal.

Process for preparing hydrogen peroxide from the elements

Catalysts produced by electroless deposition of at least one platinum metal on a nonporous nonmetallic support can be used for the synthesis of hydrogen peroxide from the elements and for the hydrogenation of organic compounds.

Method for producing catalysts consisting of metal of the platinum group by means of electroless deposition and the use thereof for the direct synthesis of hydrogen peroxide

The invention relates to a supported platinum group metal catalyst obtainable by controlled electroless deposition of at least one platinum group metal from a deposition solution which comprises

Supported catalyst consisting of metal of the platinum group and obtained by means of controlled electroless deposition

In a process for preparing an aqueous and/or alcoholic solution of hydrogen peroxide by reaction of hydrogen and oxygen in a trickle-bed reactor over a supported catalyst including a noble metal, the apparent flow direction of the gas stream and the apparent flow direction of the liquid stream are not parallel to one another. The apparent flow direction of the gas stream preferably runs radially from the longitudinal axis to the circumference of the reactor. The process allows high gas throughputs with a small pressure drop.

Preparation of hydrogen peroxide from hydrogen and oxygen

The present invention relates to a process for the preparation of phosphonomethylglycine, wherein N-phosphonomethyliminodiacetic acid N-oxide is brought into contact with a catalytically effective amount of thiocyanic acid or a salt thereof.

Method for the production of phosphonomethylglycine

The present invention relates to a process for the preparation of phosphonomethylglycine in which N-phosphonomethyliminodiacetic acid N-oxide is brought into contact with a catalytically active quantity of at least one catalyst, selected from amongst a thionyl halide, ammonium dithionite or an alkali metal dithionite, a dialkyl sulfite, sulfur dichloride, sulfur dioxide and sulfurous acid, in a reaction chamber by metering the N-phosphonomethyliminodiacetic acid N-oxide into the reaction chamber in such a way that always at least 50% of the N-oxide metered into the reaction chamber are converted.
