    摘要： The invention is directed to the preparation of organic or aqueous-organic hydrogen peroxide solutions by direct synthesis from a non-explosive gaseous mixture containing hydrogen and oxygen. The process is carried out in the presence of a noble metal catalyst, using a reaction medium containing a halide and a strong acid. It can be performed in a stainless steel reactor without corrosion occurring to the reactor material if, during the reaction, the surface of the stainless steel is, at no place, in permanent contact with the gaseous mixture passing through the reactor.

    摘要： Aqueous-organic or organic hydrogen peroxide solutions can be produced by direct synthesis in the presence of a catalyst fixed bed and an organic solvent. According to the invention, a non-explosive gas mixture comprising H2 and O2 is employed and a liquid reaction medium comprising organic solvent and bromide and/or iodide is passed over the fixed bed with a cross-section loading of at least 0.3 m/h. In the case of a trickle bed procedure with a cross-section loading of 0.3 m/h to 2 m/h, 4 to 10 wt. % methanolic H2O2 solutions can be prepared with a high productivity.

    摘要： The invention relates to a process for producing hydrogen-containing chlorosilanes by reducing Si-based deposits of solid material during the operation of a pressurised reactor comprising one or more reaction spaces, wherein at least one organochlorosilane is reacted with hydrogen in at least one of these reaction spaces for at least some of the time, characterized in that at least one of the optionally two or more reaction spaces in which this reaction takes place is supplied with additional HCl for at least some of the time. The additional HCl is preferably produced by hydrodehalogenation of silicon tetrachloride with hydrogen in at least one of the optionally two or more reaction spaces of the reactor.
