项目摘要
From tires to bubble gum, butyl rubber has found abundant applications across the modern world. Unfortunately, the catalysts used to synthesize butyl rubber are not discreet complexes, but nebulous mixtures of Lewis acids and additives. This results in a reaction "black-box" which can limit reproducibility and inhibit study to improve the process. Arlanxeo is interested in gaining an understanding of what the actual nature of the current catalysts are, which will also assist in the process of developing new discreet Lewis acid catalysts for butyl rubber synthesis. The project will explore two objectives, the first will utilize frustrated Lewis pair chemistry to identify the active initiator species. This will allow for the design of more effective initiator systems for Arlanxeo. The second objective will take a systematic approach to explore the impacts of the coordinating ability of the anion on the polymerization reaction. By combining these data with our fluorescent Lewis adduct measurements, we hope to paint a complete picture of what factors influence butyl rubber initiation.
从轮胎到泡泡糖,丁基橡胶在现代世界有着广泛的应用。不幸的是,用于合成丁基橡胶的催化剂不是离散的络合物,而是刘易斯酸和添加剂的模糊混合物。这导致反应“黑匣子”,其可限制再现性并抑制改进工艺的研究。Arlanxeo有兴趣了解当前催化剂的实际性质,这也将有助于开发用于丁基橡胶合成的新型离散刘易斯酸催化剂。该项目将探讨两个目标,第一个将利用挫折刘易斯对化学来确定活性引发剂物种。这将允许为Arlanxeo设计更有效的引发剂系统。第二个目标将采取系统的方法来探索阴离子的配位能力对聚合反应的影响。通过将这些数据与我们的荧光刘易斯加合物测量相结合,我们希望描绘出影响丁基橡胶引发的因素的完整画面。
