Title: The Innovative Contributions of Karl-Heinz Giselbrecht
Introduction
Karl-Heinz Giselbrecht is a notable inventor based in Pasching, Austria. He has made significant contributions to the field of chemistry, particularly in the preparation of L-aspartic acid. With a total of 2 patents, Giselbrecht's work showcases his expertise and innovative approach to chemical processes.
Latest Patents
Giselbrecht's latest patents focus on improved methods for preparing L-aspartic acid. The first patent describes a process that utilizes an enzyme-catalyzed reaction of fumaric acid with ammonia. In this method, L-aspartic acid is precipitated out using nitric acid, and the resulting mother liquor undergoes nanofiltration. The second patent also addresses the preparation of L-aspartic acid through a similar enzyme-catalyzed reaction. In this process, after the reaction is complete, excess ammonia is removed from the mixture. L-aspartic acid is then precipitated by adding acetic or formic acid, which are subsequently released from the mother liquor by adding fumaric acid. This innovative approach allows for the reuse of ammonia and acids in subsequent cycles, enhancing efficiency.
