With a total of three patents to his name, Stock's work has advanced the methods used in the chemical industry.

Latest Patents

Jürgen Stock's latest patents focus on innovative methods for the epoxidation of olefins using hydrogen peroxide. The first patent describes a method where olefins are continuously reacted with hydrogen peroxide in a mixed reactor. This process involves a water-soluble epoxidation catalyst, which comprises a manganese complex. The reaction occurs in a mixture that includes both an aqueous liquid phase and an organic liquid phase. The design allows for the continuous withdrawal of the reaction mixture, which is then separated into aqueous and organic phases. A portion of the separated aqueous phase is recycled back into the reactor, ensuring that the combined hold-up time remains under 15 minutes.

The second patent also addresses the epoxidation of olefins with hydrogen peroxide. In this method, the olefin is reacted continuously in a loop reactor, maintaining the concentration of hydrogen peroxide in the aqueous phase at less than 1.0% by weight. This innovative approach enhances the efficiency and effectiveness of the epoxidation process.
