Curriculum Vitae

In October 2015 Till Köhler started studying chemistry at the department of chemistry and chemical biology at TU Dortmund. After his bachelor thesis in organic chemistry in September 2018, he stayed at TU Dortmund for his master studies. Within the next two years, he focused on technical chemistry and homogeneous catalysis. He successfully completed his master thesis in the field of ‘oxidative cleavage of methyl oleate’ in September 2020 at the chair of industrial chemistry. During his masters, he received the “Deutschlandstipendium” by BASF and Lanxess. He started his doctoral studies in September 2020.

Research Topic

In chemical Industry, nitriles are versatile products featuring a various follow-up chemistry e.g. amines through hydrogenation or even Amides/Carbonic acids by hydrolysis. Homogeneous catalyzed addition of hydrogen cyanate to olefins can be used to produce nitriles. This so-called hydrocyanation of olefins offers great benefits over more traditional synthesis like Kolbe-nitrile synthesis, that is based on nucleophilic substitution. The low reactivity as well as moderate selectivity towards the linear nitrile while using non-activated olefins like 1-hexene, remains challenging in the application of hydrocyanation in chemical industry.

A novel approach in ligand design for increased catalysts activity while keeping high regioselectivity is highly promising.

Reaktion: Hydrocyanation: R-C=C ->(+HCN,+cat.) R-CCN-C-H (branched nitrite) + R-CH-C-CN (linear nitrite)

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”.
