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.

摘要CHE-0517017 Hinch/Rutgers该GOALI项目阐述了有机硅直接催化合成的详细机理。 在分析和表面化学项目的支持下，罗格斯大学的Hinch教授和她的同事，以及坦普尔大学的Strongin教授和他的同事，正在与道康宁公司的合作者合作，研究Rochow工艺直接合成有机硅的详细机制和动力学。 超高真空表面光谱用于表征铜上的模型单晶硅和硅上的铜催化剂，以及用添加剂如Sn和Zn促进的模型催化剂。 还对道康宁公司使用的促进型商业催化剂进行了原位研究。 在分析和表面化学项目的支持下，罗格斯大学的Hinch教授和Temple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理和动力学。 模型催化剂系统和真实的工作催化剂都在进行检验。 在这项工作中，将获得这一重要的商业过程的机制的基本见解。
