Curriculum Vitae

Christian Heider studied Chemistry at TU Dortmund since October 2013. In 2016 he finished his bachelor thesis with the topic „Contributions to synthesis and characterization of cationic associative copolymers“ at the laboratory of organic chemistry. In his master studies from October 2016 till March 2019 he worked at the laboratory of industrial chemistry and earned his master’s degree with his thesis on the „Investigation on the homogeneous, ruthenium-catalyzed amination of alcohols in reactive ionic liquids with integrated catalyst recycling“. Since June 2019 he works as a research associate at the laboratory of industrial chemistry supported by a Ph.D. scholarship by „Evonik Stiftung“.

Research Topic

Amines are one oft he most important building blocks for agrochemicals, pharmaceuticals and other fabrics of our everday live. Homogeneous catalyzed amination reaction starting from various platform chemicals to synthesize primary, secundary and tertiary amines are well established. But when ammonia is used as amination reagent a mixture of products are often obtained, due to the higher reactivity of primary amines compared to ammonia.

Reaktion von R-C-Oh; R-C=; R-C=O; R-C-X mit NH3 und katalysiert zu R-C-NH2 (aliphatic, primary amine) -> undesired secondary+tertiary amines

For large-scale synthesis a control of the consecutive reactions is necessary. For this reason, further reasearch is needed into catalyst systemes and process engineering.

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”.
