  • Platinum catalyst for hydrosilations
    Patent number: 6087523
    Abstract: 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.
