Understanding the Direct Synthesis on promoted Cu/Si alloy surfaces

这个GOALI项目研究了直接催化合成有机硅的详细机理。在分析和表面化学项目的支持下，Hinch教授和她在罗格斯大学的同事，以及Strongin教授和他在坦普尔大学的同事，正在与道康宁的合作者一起研究直接合成有机硅的Rochow过程的详细机制和动力学。采用超高真空表面光谱法对铜上单晶硅模型、铜上硅催化剂模型、Sn、Zn等助剂促进的催化剂模型进行了表征。此外，还对道康宁公司所使用的催化剂进行了现场研究。来自这些基础研究的信息将对这项具有重要商业意义的技术提供至关重要的理解。在分析和表面化学项目的支持下，罗格斯大学的Hinch教授和坦普尔大学的Strongin教授以及他们在道康宁的合作者正在研究有机硅直接合成的详细机制和动力学。模型催化剂体系和实际工作催化剂正在进行研究。在这项工作中，将获得对这一重要商业过程机制的基本见解。

AbstractCHE-0517017Hinch/RutgersThis GOALI project addresses the detailed mechanism of the direct catalytic synthesis of silicones. With the support of the Analytical and Surface Chemistry Program, Professor Hinch and her colleagues at Rutgers, and Professor Strongin and his colleagues at Temple, are working with collaborators at Dow Corning to examine the detailed mechanism and kinetics of the Rochow process for the direct synthesis of silicones. Ultra high vacuum surface spectroscopy is used to characterize model single crystal silicon on copper and copper on silicon catalysts, and model catalysts promoted with additives such as Sn and Zn. In situ studies of promoted commercial catalysts used by Dow Corning are also carried out. Information from these fundamental studies will provide crucial understanding of this commercially important technology.With the support of the Analytical and Surface Chemistry Program, Professor Hinch at Rutgers and Professor Strongin at Temple and their collaborators at Dow Corning are examining the detailed mechanism and kinetics of the direct synthesis of silicones. Both model catalyst systems and real working catalysts are being examined. Fundamental insights into the mechanism of this important commercial process will be obtained in this work.
