Title: Jost H Manegold: Innovator in Chemical Processes
Introduction
Jost H Manegold is a notable inventor based in Lambsheim, Germany. He has made significant contributions to the field of chemical engineering, particularly in the preparation of dicarboxylic acids and aliphatic dinitriles. With a total of 3 patents to his name, Manegold's work has had a considerable impact on industrial processes.
Latest Patents
One of his latest patents is focused on the workup of mother liquors resulting from the preparation of adipic acid. This innovative process involves the oxidation of cyclohexanol or cyclohexanone with nitric acid, followed by the removal of nitric acid through azeotropic distillation with water. The resulting melt is then heated between 130°C to 180°C and dissolved in water. The aqueous solution is treated with cation exchangers, and after evaporating the water, the dicarboxylic acid melt is heated at temperatures ranging from 200°C to 240°C, ultimately leading to the distillation of a mixture of dicarboxylic acids. Another significant patent involves the preparation of aliphatic dinitriles, which are synthesized by reacting aliphatic dicarboxylic acids with ammonia at temperatures between 200°C to 500°C in the presence of zeolites as catalysts.
