Reaction Equipment

Autoclaves

Autoclaves:

  • Different sizes of stainless steel autoclaves à 25 mL to 5000 mL, leakproof up to 150 bar
  • Different Sizes of Glass autoclaves à 20 mL to 200 mL, leakproof up to 10 bar
  • Special reactor concepts: Glass window reactor, Jet-Loop Reactor, Taylor Couette Reactor, ATR-probe reactor, IR-glass window reactor

We use it for:

  • Pressure Experiments
  • Getting insight in the phase behaviour of biphasic mixtures
  • Investigating influence of reactor concept on the reaction performance in biphasic mixtures
  • Investigating the reaction in situ by ATR measurements

Dosing and Sampling

Dosing:

  • Gases (hydrogen, carbon monoxide, syngas, argon, nitrogen)
  • Liquid gases (ammonia, butadiene, isobutene)
  • Liquids (continuos dosing over HPLC-pump)

Sampling:

  • Gases  →  gas uptake measurements over mass flow indicators
  • Liquids  →  automatic sampling system
  • Online GC  →  automated measurements of the reaction system

We use it for:

  • Investigations in the reaction performance of liquid gases
  • Kinetic measurements
  • Monitoring of continous experiments in miniplant scale

Purification and Recovery

Purification methods:

  • Distillable compounds à Kugelrohr- / Spaltrohrdistillation, large distillation column
  • Column chromatography
  • Preparative HPLC column

Recovery methods:

  • Monophasic systems à crystallization, membranes
  • Biphasic systems à decanter, extractors (e.g. rotating disc contactor)
  • Online GC à automated measurements of the reaction system

We use it for:

  • Purification of value products
  • Recovery of precious transition metal catalysts

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”.
