专利号:US-6166237-A 优先权日:1999-08-13 标题:Removal of dissolved silicates from alcohol-silicon direct synthesis solvents 发明人:SIMANDAN TIBERIU LADISLAU; MENDICINO FRANK D 权利人:CROMPTON CORP 摘要:Dissolved silanes, silicones and silicates from solvents used in the slurry phase Direct Synthesis of alkoxysilanes are removed by adding a compatabilizing agent and water 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.
