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.

标题 :Synthesis of hydrous magnesium silicates
发明人：NEUMANN BARBARA SUSAN; SANSOM KEITH GEOFFREY
权利人:LAPORTE INDUSTRIES LTD
摘要:Hydrous magnesium silicates having a crystal structure similar to that of natural hectorite may be prepared utilising as starting material a novel intermediate which may be prepared from talc. The novel intermediate, 'mesotalc' is the product obtained by heating a mixture of talc and sodium carbonate so as to modify the talc structure while controlling the heating to avoid destroying it.
