Title: Gerd Greger: Innovator in Chemical Processes
Introduction
Gerd Greger is a notable inventor based in Kempen, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production and separation of toluenediamine. With a total of 2 patents, his work has had a considerable impact on the industry.
Latest Patents
Gerd Greger's latest patents focus on innovative processes for the preparation and separation of toluenediamine. One of his patents details a method for producing and separating toluenediamine from by-products of the reaction. This process involves treating amine mixtures generated during the production of diaminotoluene by hydrogenating dinitrated aromatic compounds. The method includes the removal of any water of reaction and solvent from the diaminotoluene isomer mixture. Subsequently, low-boiling TDA isomers are separated using a TDA isomer distillation column. The remaining bottom phase, which contains a mixture of m-TDA and high-boiling materials, is concentrated until the high-boiling material content is between approximately 25 to 60 wt. %. This concentrated bottom phase is then mixed with o-TDA in a specific ratio, allowing for the recovery of a m-/o-TDA mixture that is returned to the distillation column.
Career Highlights
Throughout his career, Gerd Greger has worked with prominent companies in the chemical industry, including Bayer Aktiengesellschaft and Bayer Materialscience AG. His expertise in chemical processes has been instrumental in advancing the production techniques used in these organizations.
