This project addresses fundamental issues in catalysis for carbon dioxide reactivity with glycerol to carbonic esters. Two waste chemicals are, therefore, involved as renewable feedstocks for making high-value products. The perspective is to get an entry for developing CO2-neutral reactions of promising development and increasing importance for the future. Emphasis is put on molecular catalyst design and catalytic reactor optimization to promote the reaction and tune selectivity for glyceric carbonates. To achieve this goal three partners (CNRS, Dortmund University and New University of Lisbon) will share their complementary competences in close collaboration. The new trans-national cooperation will benefit from tightly linked methodologies in molecular catalysis: precatalyst synthesis and characterization, high-pressure catalytic reaction, reaction kinetics, mechanistic studies, reactor technology, and fluid phase thermodynamics. Coordination chemistry of glycerol-based ligands targeting the reactivity with carbon dioxide and relevant mechanistic studies in correlation with catalytic activity have been unexplored. The knowledge acquired during this project will set the rules of metal binding to polyols and CO2 for catalysis. Metal-oxygen bonds are the new key players for oxygenated feedstock transformation, just as metal-carbon bonds dictate the pathways to C-C couplings to produce oligomers and polymers from olefin feedstock. The know-how acquired in reactor technologies and fluid phase thermodynamics will provide the basic requirements for the catalytic process to be performant.

本计画主要探讨二氧化碳与甘油反应生成碳酸酯之催化反应之基本问题。因此，两种废弃化学品被用作制造高价值产品的可再生原料。前景是获得一个入口，发展有前途的发展和日益重要的未来CO2-中性反应。重点介绍了分子催化剂的设计和催化反应器的优化，以促进反应和调整甘油碳酸酯的选择性。为了实现这一目标，三个合作伙伴（CNRS，多特蒙德大学和里斯本新大学）将在密切合作中分享他们的互补能力。新的跨国合作将受益于紧密联系的分子催化方法：催化剂前体合成和表征，高压催化反应，反应动力学，机理研究，反应器技术和流体相热力学。甘油基配体的配位化学靶向与二氧化碳的反应性和与催化活性相关的相关机理研究尚未探索。在该项目中获得的知识将确定金属与多元醇和CO2结合的催化规则。金属-氧键是含氧原料转化的新的关键参与者，正如金属-碳键决定了C-C偶联的途径，以从烯烃原料生产低聚物和聚合物。在反应器技术和流体相热力学方面获得的专门知识将为催化过程的性能提供基本要求。
