Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical chemistry and Pharmaceutical analysis Student: Miroslav Jankových Supervisor: doc. PharmDr. Radim Kučera, PhD. Consultant: PharmDr. Tomáš Holas, PhD. Title of diploma thesis: The electrochemical reduction of the nitro group in a flow reactor The aim of this diploma thesis is to study the electrochemical reduction within the flow reactor. The combination of these two methods provides enviromentaly-friendly and interesting method for the manufacturing of active pharmaceutical ingredients. Our object was to find out if the reaction really goes on. After that our goals were to optimize the reaction parameters. We executed some of the experiments to understand the parameters such as: flow rate, voltage, electric current, electrolyte. These parameters we combined to see their effect on the reaction results. The outcome of the thesis is mainly basic information about impact of parameters mentioned above. From the series of experiments the best parameters are flow rate 0,1 ml.min- 1 , voltage 0,8 - 2,0 V, electric current 100 - 150 mA, electrolyte NH4Cl, reaching conversion up to 96%.
