Abstract
A process for manufacturing an organosilicon product having a stabilized low color and no formation of black particles during storage includes (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; (b) separating the heterogeneous precious metal catalyst from the organosilicon product; and (c) recovering the heterogeneous precious metal catalyst.
