Title: The Innovative Contributions of Hans Hellbach
Introduction
Hans Hellbach is a notable inventor based in Lampertheim, Germany. He has made significant contributions to the field of chemistry, particularly in the development of processes for the preparation of various chemical compounds. With a total of 7 patents to his name, Hellbach's work has had a considerable impact on the industry.
Latest Patents
Among his latest patents is a process for the preparation of nicotinamide. This innovative method involves the amidation of a nicotinic acid/nicotinamide melt, followed by vacuum distillation of the amidation mixture. The process allows for the removal of nicotinamide as the bottom product while recycling the top product, which is depleted of nicotinamide, back into the amidation stage along with fresh amounts of nicotinic acid. Another significant patent involves the preparation of hexamethylene 1,6-diisocyanate and/or isomeric aliphatic diisocyanates. This process entails vaporizing the corresponding dialkylurethanes without decomposition at temperatures ranging from 220°C to 300°C, preferably under reduced pressure. The dialkylurethane vapors are then subjected to thermal cleavage under reduced pressure and at elevated temperatures, resulting in the production of diisocyanates and alcohol.
