    摘要： The invention relates to a method for producing silicon by reacting silicon oxide at an elevated temperature, silicon carbide and, optionally, a second carbon source being added to the reaction mixture. The invention further relates to a composition that can be used in the disclosed method. The essential part of the invention is the use of silicon carbide as a reaction initiator and/or reaction accelerator during the production of silicon or, alternatively, in nearly equimolar amounts for the production of silicon.

    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.
