Abstract

The present invention relates to a process for neutralizing and reducing the residual halogen content in alkoxysilanes and alkoxysilane-based compositions, which includes treating an alkoxysilane having a residual content of acidic halide, or a corresponding alkoxysilane-based composition, with metallic magnesium in the presence of an alcohol and separating off the resulting solids.
