Abstract: The present invention relates to a process for preparing mercaptoorganyl(alkoxysilanes), by hydrogenating bis(alkoxy-silylorganyl) polysulphides with hydrogen in the presence of at least one alcohol and a doped metal catalyst. The doped metal catalyst comprises at least one substance from the group consisting of iron, iron compound, nickel, nickel compound, palladium, palladium compound, osmium, osmium compound, ruthenium, ruthenium compound, rhodium, rhodium compound, iridium and iridium compound plus at least one doping component.

Abstract: The invention concerns a process for producing mercaptoorganyl(alkoxysilanes), wherein bis(alkoxysilylorganyl)polysulfides are hydrogenated at temperatures of <190° C. and pressures of <100 bar with hydrogen and a transition metal catalyst without the addition of water, alcohol or H2S.

Abstract: The invention relates to a process for the preparation of mercaptoorganyl(alkoxysilanes), wherein bis(alkoxysilylorganyl)polysulfides are hydrogenated with hydrogen and a transition metal catalyst in a solvent without the addition of alcohols, H2S or water.

Abstract: A searchable library of catalysts, wherein each catalyst is defined by a specific performance profile, is created by a series of steps. The first involves the selection of a catalyst, a substrate and at least two different chemical reactions for catalyst characterization. The next involves contacting the catalyst and substrate under conditions suitable for the selected reaction and measuring for each of the selected reactions a reaction parameter, which is associated with catalyst performance. The catalyst performance is then determined and a value assigned. The performance profile is a table including the performance values. The catalyst is then placed into a library, which is searchable based on the performance profile.
