    摘要: A hydrosilation process comprising contacting a silicon hydride with an unsaturated reactant in the presence of a platinum catalyst supported on porous aluminum oxide having an acidity of pH 2 to 7. The process is particularly useful for the hydrosilation of unsaturated reactants where the unsaturation is in the internal portion of the reactant's structure, for example, as in cyclopentene and cyclohexene.

    摘要: Dispersion stabilized zeolite supported metal catalysts are provided as bimetallic catalyst combinations. The catalyst metal is in a reduced zero valent form while the dispersion stabilizer metal is in an unreduced ionic form. Representative catalysts are prepared from platinum or nickel as the catalyst metal and iron or chromium dispersion stabilizer.
