    摘要: The invention relates to a process for treating a substantially water-containing amino-functional, polymeric catalyst precursor while retaining the inner porous structure thereof and the outer spherical form thereof to form a catalyst, in which the catalyst precursor is treated at mild temperatures and under reduced pressure to prepare a catalyst having a water content below 2.5% by weight. The process is preferably integrated into an industrial scale process for preparing dichlorosilane, monosilane, silane, or solar silicon or semiconductor silicon from silanes.

    摘要: Alkoxysilanes are prepared by a process, comprising: (i) reacting a chlorosilane with an alcohol in a water-free and solvent free phase with removal of the liberated hydrogen chloride; (ii) transferring the resultant product mixture into a liquid phase to be distilled and adding a metal alcoholate to the product mixture in the liquid at a temperature in the range from 10-60° C., and thoroughly mixing the neutralized product mixture, said alcoholate being employed in an equimolar amount or in a stoichiometric excess based on the amount of acidic chloride, and (iii) purifying the treated product mixture by distillation under reduced pressure, thereby preparing alkoxysilanes which are low in acidic chloride or essentially free of acidic chloride.
