Title: Walter Bieg: Innovator in Chemical Processes
Introduction
Walter Bieg, an accomplished inventor based in Gruenstadt, Germany, has made significant contributions to the field of chemical processes. With a total of 4 patents to his name, Bieg's work focuses on improving methods for producing essential chemical compounds.
Latest Patents
Among Walter Bieg's latest innovations are two noteworthy patents. The first describes a **method for the continuous production of 1,3-dioxolan-2-ones**. This innovative process involves reacting oxiranes with carbon dioxide in the liquid phase while utilizing a catalyst. The method employs a two-part reactor where the first section facilitates backmixing to achieve at least 80% conversion of the oxirane. In the second section, the reaction completes under non-backmixing conditions, with carbon dioxide passed in countercurrent to the oxirane throughout the reactor.
The second patent details a **process for purifying indigo**. This method includes stripping the synthesized aqueous alkaline indoxylate solution of impurities before oxidation to indigo. The purification process is performed in the absence of oxygen, either by distillation or by passing in steam or an inert gas. The resulting indigo is then treated with a dilute hydrogen peroxide solution to ensure high purity levels.
