In October 2013 Anna Kampwerth started studying chemistry at the TU Dortmund and finished her bachelor thesis with the topic “Investigation on the tandem reaction of hydroformylation and aldol condensation of 1-octene with subsequent reductive amination” at the laboratory of industrial chemistry in March 2017. During her master studies from April 2017 to April 2019 she was partially supported by LANXESS AG as part of the “Deutschlandstipendium”. In March 2018 she went to Japan and studied at Tohoku University in Sendai for one semester as an exchange student of the Cooperative Laboratory Study Program (COLABS). In the group of Prof. Dr. Terada she completed a research project with the topic “Study on synthesis of alkenyl aryl ethers through SNAr reaction utilizing [1,2]-phospha-Brook rearrangement”. During this time she received a scholarship from the Japan Student Services Organization (JASSO). In 2019 she earned her master’s degree with her thesis on the “Development of two different recycling approaches in the telomerization of β-myrcene with dimethylamine”. Afterwards, she gained industrial work experience through a 6-month internship at Saltigo GmbH (LANXESS AG) in Leverkusen working on the characterization of flow reactors. Since December 2019 she is working as a research associate at the laboratory of Industrial Chemistry.
Homogeneous catalysts are mostly used for research or in pharmaceutical chemistry. In the context of Sonderforschungsbereich/ Transregio 63 (SFB/ TR 63), financed by the DFG, the chances of homogeneous catalysts applications in industrial processes should be improved.
In this research the synthesis of amines with integrated catalyst recycling in thermomorphic multiphase systems should be investigated.
Possible reactions are on the one hand a two-step synthesis through a hydroformylation and a reductive amination. On the other hand both steps can be done together in a hydroaminomethylation (Figure 1). In the end of this work the both ways should be compared. In both ways the synthesis should be done in a thermomorphic multicomponent system (TMS). TMS offer a promising way for the catalyst recycle like it is shown in Figure 2.

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”.
