Title: Lutz Hippe: Innovator in Sodium Monosulfide Production
Introduction
Lutz Hippe is a notable inventor based in Ober-Ramstadt, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production of sodium monosulfide. With a total of 3 patents to his name, Hippe's work has advanced the methods used in this important chemical process.
Latest Patents
Hippe's latest patents include innovative methods for preparing sodium monosulfide. The first method, titled "Method of preparing Na.sub.2 S (II)," involves reacting sodium polysulfide with sodium under protective gas. In this process, sodium polysulfide is finely distributed in a receiver preheated to temperatures between 100°C and 150°C. Liquid sodium is gradually added while maintaining the reaction mixture's temperature between 120°C and 250°C. The initial product is then allowed to post-react at higher temperatures until a Na.sub.2 S content of at least 95% by weight is achieved.
The second method, "Method of preparing Na.sub.2 S (III)," also focuses on producing sodium monosulfide by reacting sodium and sulfur under protective gas. In this method, the initial materials are preheated to 120°C-150°C, and sodium and sulfur are alternately added under intensive mixing. Similar to the first method, the reaction mixture's temperature is maintained between 120°C and 250°C, followed by a post-reaction phase at higher temperatures to achieve the desired Na.sub.2 S content.
