Abstract:
1. A process for manufacturing an organosilicon product having as stabilized low color and no formation of black particles during storage, the process comprising the steps of a) reacting an unsaturated compound with a silicon compound having a reactive Si—H bond under hydrosilylation conditions in a reaction zone in the presence of a heterogeneous precious metal catalyst to provide an organosilicon product having a color of less than 40 pt/co, wherein the unsaturated compound is 1-octene or Eugenol; b) separating the heterogeneous precious metal catalyst from the organosilicon product; and c) recovering the heterogeneous precious metal catalyst, wherein the organosilicon product is a component in at least one of a personal care composition, an agricultural composition, a home care composition, a polyurethane foam composition, or a plastic additive composition.
