Polycondensation in microreactors

In the scope of the BMBF-funded project POKOMI (Förderkennzeichen 16SV1981) polymerization processes using microtechnology are investigated, focusing on the Suzuki-Polycondensation as reaction example. This C-C-coupling reaction is a common method for the production of polymeric, light emitting semiconductors, being applied in display technology. The homogenously catalyzed polycondensation is carried out in a biphasic solvent system. Thus, phase contacting is a matter of particular interest.

The aim of this project is the development of a microtechnology based pilot plant in order to enable the realization of a production plant based on microstructured devices. The advantages of microtechnology lead to process optimization compared to conventional process, especially concerning the enhanced phase contacting. IMM and the project partner Mikroglas chemtech are decisively involved in development of microstructured devices, i.e. microreactors or micromixers. Additionally an extraction-unit (membrane separator as well as mixer-settler) for the separation and purification of the product phase is developed at IMM. Further project partners are the Merck KGaA, hte AG, Stiftung caesar and the Jumo GmbH.
