Homogeneous Catalytic Hydrogenations and Photocatalytic Reactions in Microstructured Reactor Systems
Pavlorková, Jana ; Křišťál, Jiří ; Drhová, Magdalena ; Hejda, S. ; Klusoň, Petr
Microstructured reactor (MSR) systems play a key role in modern industrial processes which require obtaining products of predefined high purity and quality. MSR systems are being currently successfully used for this purpose. Their unique features rest in the high active surface to the reaction volume ratio ensuring easier and proper maintaining of reaction conditions as well as the fast heat, mass and momentum transfer. The use of MSR systems leads to the elimination of side products and consequently to the elimination of additional separation processes. This fact makes the microreactor technology more straightforward in comparison with the conventional batch reactor technology. MSR are being tested for the production of fine-chemical industry and special small-scale productions as well. Two different commercial MSR systems were tested: the microchip reactor system Labtrix (Fig. 1) and the photochemical microreactor based on the Modular Micro Reactor System (MMRS) platform. In this contribution we present these two MSR systems with their applications: the stereoselective hydrogenation, and the photochemical oxidation.

Microreactor Platforms for HomogeneousHydrogenations and Photocatalytic Reactions
Pavlorková, Jana ; Křišťál, Jiří ; Drhová, Magdalena ; Hejda, S. ; Klusoň, Petr
Research was focused on a model reaction - photochemical degradation of 4-chlorophenol, which by the way, is widely used as an herbicide, fungicide or insecticide and it is listed among top priority pollutants. The degradation occured via photochemical proces by the irradiation in a combination with a photosensitizer. UV/VIS light was generated by i high pressure mercury lamp. In this reaction phthalocyanine acts as the photcatalyst generating singlet oxygen.

Microreactors for Studying Enantioselective Reactions
Pavlorková, Jana
The aim of this thesis is optimization of given microreactor system Labtrix and reaction conditions for chosen enantioselective reactions. Our future vision is to set up and offer this system to pharmaceutical industry for purpose of synthetizing optically pure products and other chemicals for life and material sciences.
