ABSTRACT:
Dissolved silanes, silicones and silicates from solvents used in the slurry phase Direct Synthesis of alkoxysilanes are removed by adding a carboxylic acid such as formic acid to generate filterable precipitates and reusable solvent. The solvents are thereby remediated and made suitable for reuse in Direct Synthesis processes. Foaming is reduced with the remediated solvent and silicon conversion rates are higher. The precipitates are easily filtered and retain negligible quantities of solvent.
