项目摘要

The proposed project aims at a knowledge-based understanding of the interactions, structure and dynamics of ionic liquid based reactive systems in the presence of compressed carbon dioxide. There is currently no systematic study of how the presence of compressed carbon dioxide (CO2) affects the interaction of ionic liquids (ILs) with dissolved substrates, catalysts, or products. At the moment there is even a lack of knowledge about how the solubility of CO2 in different ILs can be correlated with the structures of anions and cations. Moreover, it is still unknown if the solubility of reactive gases (such as hydrogen, ethylene, oxygen, etc.) follow the same trends and are based on the same interactions in neat ILs and in the presence of compressed CO2. Furthermore, a detailed investigation of the effect of compressed CO2 on the performance of various catalytic systems in ILs (e.g. selectivity, reactivity) is still missing. To address these questions, the system IL/CO2 will be extensively studied in this project with IR and NMR spectroscopic techniques, and with selected catalytic test-reactions as molecular probes. The outcome of these investigations will then provide the essential information to rationally exploit the unique properties of the IL/CO2 system and may ultimately lead to the design of task-specific ILs for catalytic reactions in combination with compressed or supercritical CO2.

拟议的项目旨在以知识为基础的理解的相互作用，结构和动力学的离子液体为基础的反应系统在压缩二氧化碳的存在。目前还没有系统的研究如何压缩二氧化碳（CO2）的存在影响离子液体（IL）与溶解的底物，催化剂，或产品的相互作用。目前，甚至缺乏关于CO2在不同离子液体中的溶解度如何与阴离子和阳离子的结构相关的知识。此外，还不知道反应性气体（如氢气、乙烯、氧气等）的溶解度是否与反应性气体的溶解度有关。遵循相同的趋势，并基于相同的相互作用，在净离子液体和压缩CO2的存在下。此外，压缩CO2对离子液体中各种催化系统性能（例如选择性，反应性）的影响的详细调查仍然缺失。为了解决这些问题，IL/CO2系统将在本项目中广泛研究IR和NMR光谱技术，并与选定的催化测试反应作为分子探针。这些调查的结果，然后将提供必要的信息，合理利用IL/CO2系统的独特性能，并可能最终导致特定任务的IL的催化反应的设计与压缩或超临界CO2。
