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.

Location & approach
The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is “Dortmund-Eichlinghofen” (closer to South Campus), and from B 1 / A 40 “Dortmund-Dorstfeld” (closer to North Campus). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.
To get from North Campus to South Campus by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at North Campus and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.
TU Dortmund University has its own train station (“Dortmund Universität”). From there, suburban trains (S-Bahn) leave for Dortmund main station (“Dortmund Hauptbahnhof”) and Düsseldorf main station via the “Düsseldorf Airport Train Station” (take S-Bahn number 1, which leaves every 20 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.
You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station “Stadtgarten”, usually lines U41, U45, U 47 and U49. At “Stadtgarten” you switch trains and get on line U42 towards “Hombruch”. Look out for the Station “An der Palmweide”. From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop “Dortmund Kampstraße”. From there, take U43 or U44 to the stop “Dortmund Wittener Straße”. Switch to bus line 447 and get off at “Dortmund Universität S”.
The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on North Campus. One (“Dortmund Universität S”) is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the “Technologiepark” and (via South Campus) Eichlinghofen. The other station is located at the dining hall at North Campus and offers a direct connection to South Campus every five minutes.
The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent “Technologiepark”.
