Bernd Rienhoff started studying chemistry at TU Dortmund at the department of chemistry and chemical biology in Oct. 2017 and finished his bachelor thesis with the topic “Synthesis of xanthene-based pyrrole-functionalised ligands and investigation of their performance in hydroaminomethylation” in 2020.
He continued with his master studies at TU Dortmund and received the “Deutschlandstipendium” scholarship first from RAG-Stiftung and then from BASF SE between Feb. 2021 and Mar. 2022.In 2022 he finished his master’s degree after three semesters with the thesis “Hydrocyanation by Enhanced Nickel-Lewis-Acid-Cooperativity Using BiPhePhos and Investigation of the Influence of Promoters” at the chair of Industrial Chemistry (TC).
He joined the chair of Industrial Chemistry as a research associate in May 2022.
Amines are an important class of chemical substances and are used, for example, in pharmaceuticals, detergents and agrochemicals. Homogeneous catalysis offers an efficient way to synthesize them with high activity and yield and usually under mild reaction conditions. However, the separation of product from catalyst and its reuse/recycling is a challenge that has not been satisfactorily addressed. This still represents an obstacle to widespread application from an economic and ecological point of view. Therefore, in order to transfer the advantages of homogeneous catalysis into practice, a suitable separation/recycling concept must be an integral part of the manufacturing process. The aim of this work is to develop and investigate CO2-induced reactive extraction systems.
