| Abstract: | The nanometer cuprous oxide using as a catalyst was prepared by the method of solvothermal synthesis.Scanning electron microscope,X-ray powder diffraction and BET were used to characterize the catalysts.The process of the direct synthesis triethoxysilane via silicon-ethanol under nanometer cuprous oxide in the dodecylbenzene solvent was studied.Results show that the selectivity of triethoxysilane is 92.6% and the yield of product arrive 80.8% under the optimal conditions as follows： reaction temperature is 483 K,catalyst content is 5 wt% and silicon particle diameter is 200～320 meshes. |
