用制备的纳米氧化铜直接合成三乙氧基硅烷的研究

Nanosized Copper(Ⅱ) Oxide Catalyst Precursors for the Direct Synthesis of Triethoxysilane

合成了纳米氧化铜催化剂并进行了表征,对催化剂在溶剂中以硅粉与气态乙醇反应合成三乙氧基硅烷进行了研究,讨论了反应温度、催化剂用量、硅粉粒度、不同溶剂对反应的影响.并与CuCl催化剂进行了比较.

The process of the direct synthesis triethoxysilane via silicon-gas-ethanol and nanosized copper(Ⅱ)oxide in solvent was studied. The effect factors to reaction such as reaction temperature, the amount of CuO, silicon granularity, influences the solvent were discussed. The reaction results were compared with CuCl in the direct synthesis of triethoxysilane.
