Title: Ernst Selbertinger: Innovator in Chemical Processes
Introduction
Ernst Selbertinger is a notable inventor based in Marktl, Germany. He has made significant contributions to the field of chemical engineering, particularly in the development of processes for the manufacture of unsaturated carboxylic acid esters and the chlorination of olefins.
Latest Patents
Selbertinger holds 2 patents that showcase his innovative approaches. His first patent details a process for the manufacture of unsaturated carboxylic acid esters. This process involves the reaction of olefins or cyclo-olefins with oxygen and carboxylic acids in the gaseous phase, utilizing a catalyst containing elements from the subsidiary group VIII of the periodic system and/or compounds thereof, along with an alkali metal acetate. The reaction occurs at temperatures ranging from 100°C to 250°C and pressures from 0.5 to 21 bar absolute, with the addition of organic chlorine compounds to enhance the reaction.
His second patent focuses on the continuous chlorination of olefins in the liquid phase. This method addresses the common issue of excess chlorine used in the chlorination of ethylene, which can reduce the yield of desired products. By limiting the chlorine excess to less than 600 ppm by weight in the reaction cycle, Selbertinger's invention improves efficiency and reduces the need for laborious removal of unreacted chlorine.
Career Highlights
Throughout his career, Selbertinger has worked with prominent companies in the chemical industry, including Wacker Chemie GmbH and Hoechst Aktiengesellschaft. His experience in these organizations has contributed to his expertise in chemical processes and innovation.
