Title: Ulrich Wallbaum: Innovator in Chelating Resins
Introduction
Ulrich Wallbaum is a notable inventor based in Dollern, Germany. He has made significant contributions to the field of chemical engineering, particularly in the development of innovative processes for preparing bisphenols and improving the removal of multi-valent cations from solutions. With a total of 2 patents, Wallbaum's work has implications for various industrial applications.
Latest Patents
Wallbaum's latest patents focus on a process for preparing bisphenols using gel-type chelating resins. These bisphenols are produced through a method that enhances the removal of multi-valent alkaline earth metal and heavy metal cations. The processes utilize specific polymer resin beads that are functionalized with chelating functionalities, such as alkylaminophosphonic moieties or iminodiacetic acid moieties. The innovative aspect of his invention lies in the preparation of these beads, which have a reduced amount of cross-linking in the shell area compared to the core. Additionally, Wallbaum has developed an improved gel-type chelating resin with core/shell morphology, which exhibits remarkable combinations of dynamic capacity, osmotic shock resistance, and physical strength. This chelating resin is particularly effective for removing calcium from brine solutions before they are used in membrane electrolysis cells for chlorine production.
