Abstract

This thesis describes the development of a liquid-liquid multiphasic catalyst system (MPC-System) which is used for the homogenously catalyzed hydrogenation of CO₂ to formic acid and formic acid (FA) derivatives (formic acid-amine adducts). The synthesis of the employed catalysts is described and the optimization of the catalysis is shown. Additionally, the downstream conversion of the obtained products with methanol into methyl formate (MF) is discussed. Finally, product isolation is validated and different process strategies are envisioned. Conclusively, this work demonstrates the use of CO₂ as an alternative carbon source for the synthesis of methyl formate.
