Investigations on exothermic semi-batch reactions as a basis of the prevention of dangerous operating states

The aim of the presentation is to give an overview of the equipment and the experimental activities of the Dep. of Experimental Fluid Dynamics relating to the investigations on exothermic chemical processes.
The experimental equipment consists of several reaction calorimeters, analytical instruments and a modular computer controlled miniplant.
With the help of this equipment a number of processes were investigated on the basis of industrial contracts and research projects.
The research results are presented with two examples:

• the calorimetric investigations of the formation of Grignard reagents
• the characterization of reaction pathways and process kinetics of the catalytic hydrogenation process of a special nitroaromatic compound.

The presentation ends with an outlook onto research activities of the Dep. of Experimental Fluid Dynamics in the near future.
