Reaction Equipment



  • 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


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


  • 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
