Pioneering research: precise mechanism of the Simons process decoded.
Researchers at the Federal Institute for Materials Research and Testing (BAM) and the Freie Universität Berlin have made a breakthrough in the field of chemical synthesis. For the first time, the exact mechanism of the Simons process has been elucidated. This is an electrochemical process for the production of fluorinated organic compounds, which are of great importance in the pharmaceutical, agrochemical, plastics and electronics industries. The process is named after the American chemist Joseph H. Simons. In the process, electricity is passed through an electrolyte solution containing hydrogen fluoride, creating fluorine-containing ions that react with other molecules in the solution to form the desired compounds.
Breakthrough thanks to the latest technology
This process has been used for over 70 years, but the exact mechanism has been unclear until now. A well-known phenomenon was the formation of a black film on the nickel anode during the process. The interdisciplinary research team used the BESSY II synchrotron source at the Helmholtz Center in Berlin to analyze this film in more detail. The team used a specially developed measuring cell to carry out in-situ measurements on the anode, enabling them to observe individual atoms during electrofluorination. Their investigations revealed that highly valent nickel ions are formed in the black layer during the Simons process, which are crucial for the success of the electrofluorination. This discovery enables the Simons process to be improved in a targeted manner and made more efficient, which is of great importance for the chemical industry. The research was carried out as part of the "Fluorine-Specific Interactions" special research area funded by the German Research Foundation (DFG).
Tradition meets innovation
The Airport Region Berlin Brandenburg offers a unique combination of established companies, a dynamic start-up scene and renowned research institutions. This combination creates ideal conditions for industrial companies looking for an innovative environment. In particular, the Industry 4.0 sector benefits from these synergies and includes industries such as additive manufacturing, the electrical industry, mechanical and plant engineering, plastics, chemicals, metals and food.
Companies in these traditional industries play a central role in the development of cutting-edge technologies and promote networked supplier relationships in the capital region. This contributes significantly to the economic development and competitiveness of the region.
