    Abstract: The invention relates to shaped organosiloxanamine copolycondensates which contain Pd, Pt, Ru and/or Rh and optionally also promoters and/or moderators. The shaped copolycondensate, which is used as a support for metal, comprises units and units and/or Y-R units. R to R are a group in which R is an N-, X- or Y- bonded radical (for example an alkylene radical), and R is R -SiO3/2, H, CH3, C2H5 or C3H7. X is a divalent radical, such as -S-, -S2- to -S4-, -HN-CS-NH-, and Y is a monovalent radical, such as -CN-, -SCN, -SH, -S-CH3, -NH2, or -NH-(CH2)2-NH2. The support substance may have been crosslinked by means of Si-, Ti-, Zr- or Al-containing crosslinking agents. The metal-containing product has a spherical shape and is defined by means of the parameters sphere diameter, specific surface area, pore volume and bulk density. The invention furthermore relates to a preparation process, which can be carried out in a number of variants, and for the use of the metal-containing product as a catalyst for hydrogenation and oxidation reactions.

    Abstract: Die Erfindung betrifft gegebenenfalls mittels Si-, Ti-, Zr- und/oder Al-haltigen Vernetzern vernetztes Organosiloxanamin-Copolykondensat aus Einheiten R = direkt an N bzw. an X gebundenes Alkylen mit C1-C10, Cycloalkylen mit C5-C8 oder X = -NH2, -NH-(CH2)2-NH2, -N(CH3)2, -N(C2H5)2 -NH-(CH2)2-NH-(CH2)2-NH2, -Cl, -Br, -J, -SH, -P(C6H5)2, wobei R sec = H oder Alkyl mit C1-C3, in Form kugelförmiger Teilchen mit einem Durchmesser von 0,01 bis 3,0 mm, einer spezifischen Oberfläche von 0 bis 1000 m /g, einem spezifischen Porenvolumen von 0 bis 6,0 ml/g sowie einer Schüttdichte von 50 bis 1000 g/l. Sie betrifft weiterhin diverse Herstellungsverfahren für die geformten Copolykondensate sowie eine Verwendung jeweils bestimmter Zusammensetzungen zur Entfernung von Metallen aus Lösungen bzw. zur Adsorption von gasförmigen organischen Verbindungen und/oder von Wasserdampf.

    Abstract: A continuous process for the production of gamma -aminopropyl- trialkoxysilane and mixtures of primary and secondary aminosilanes comprises: (a) mixing gamma -chloropropyl- trialkoxysilane with ammonia in a desired ratio of reactants; (b) heating the mixture to the reaction temperature; (c) allowing the reaction to proceed in a pressure reactor with a sufficient residence time for complete conversion, during which the reaction mixture may pass through several temperature zones; (d) subsequently cooling the reaction mixture and if necessary adding an organic solvent as extraction agent; (e) separating the product gamma -amino trialkoxysilane or mixtures of primary and secondary aminosilanes from the resulting two-phase mixture, optionally by extraction; and (f) recycling the ammoniacal phase to the reactor either at stage the mixing or reaction stage.
