Title: Innovator Spotlight: Albrecht Laufer
Introduction
Albrecht Laufer, an accomplished inventor based in Essen, Germany, has made significant contributions to the field of chemistry with his innovative solutions. With a total of two patents to his name, Laufer continues to push the boundaries of scientific advancements.
Latest Patents
Laufer's recent work includes two notable patents. The first patent is for the preparation of isomer-free 2,5-dichloro-pyridine. This process involves alkoxylating 2-chloro-pyridine or 2-bromo-pyridine in the presence of a base at elevated temperatures. It further includes chlorinating the alkoxylated product with gaseous chlorine in an aqueous suspension at ambient temperatures, alongside an auxiliary base, a catalyst, and optionally an emulsifier. The final steps involve treating the isomer reaction mixture with a Vielsmeyer-Haack reagent and distilling the 2,5- and 2,3-dichloropyridine mixture with water vapor, leading to the crystallization of the product from an alcohol-water mixture.
The second patent is a process for the synthesis of L-alpha-amino acids. In this innovative method, microorganisms capable of cleaving enantioselectively 5-substituted hydantoins to L-alpha-amino acids are cultivated in a controlled batch preparation. By introducing a non-degradable enzyme inductor of a specific structure, enhanced enzyme activity and increased reaction rates are achieved.
