The Technical Laboratories (called Technikum) is a central facility for high-pressure reactions and the rectification and drying of organic solvents. The experimental autoclaves are usually manufactured by our own workshops and operated in specially enclosed pressure chambers. Glass vessels with a capacity of up to 50 L are available for pilot-scale preparations. In addition, about 1,500 liters of various solvents are distilled, cleaned and, if necessary, dried and degassed each month for all working groups. Another focus is the disposal of chemical waste, which amounts to approximately 35 tons per year.

Research Topics:

Facile Synthesis of Iron Silicates

Initiated by a serendipitous finding during the preparation of silica-supported nanoparticles, a novel method for synthesizing iron(III) silicates was developed. The known procedures to generate synthetic iron silicates typically require hydrothermal conditions with temperatures... [more]

Supercritical Carbon Dioxide

Compressed and supercritical carbon dioxide is a well-established solvent for analytical chromatography and large-scale extractions. The extraction of caffeine... [more]

The Institute’s Health and Safety Management

A large number of employees are involved in maintaining high standards of occupational health and safety. In addition to the directorium, as many as 84 appointees and six authorized persons with well-defined tasks contribute to the institutes health and safety management. The activities are ... [more]
