Title: Holger Orzesek – Innovator in Aromatic Amines and Propene Oxide Production
Introduction
Holger Orzesek, based in Gelsenkirchen-Buer, Germany, is a notable inventor with a focus on the production of chemical compounds. With two patents to his name, he has demonstrated a significant contribution to the field of chemical engineering. His innovative approaches have paved the way for advancements in the synthesis of valuable chemical intermediates and products.
Latest Patents
One of Orzesek's latest patents is a method for producing aromatic amines. In this process, aromatic amines are generated through the adiabatic hydrogenation of nitroaromatic compounds in the gas phase on one or more fixed catalysts. The process involves passing the nitroaromatic reactant over the catalyst under pressure and elevated temperature in the presence of hydrogen and water, while maintaining a substantial absence of the aromatic amine being produced.
Another significant patent involves the method for producing propene oxide. This process is characterized by the reaction of a mixture of propene and an oxygen-containing gas at temperatures ranging from 150 to 500°C. The reaction occurs in a reactor that may or may not employ a catalyst, with portions of the reactor lined with inert materials such as noble metals, glass, enamel, quartz, ceramics, and Teflon. Notably, this method achieves a selectivity to propene oxide greater than 60%.
