Title: Liane Deusser: Innovator in Chemical Processes
Introduction
Liane Deusser is a notable inventor based in Erzhausen, Germany. She has made significant contributions to the field of chemical engineering, particularly in the production of important chemical compounds. With a total of 2 patents, her work has advanced the methods used in chemical synthesis.
Latest Patents
One of her latest patents is a method of producing acetone-cyanhydrin. This innovative process allows for the production of acetone-cyanhydrin in a gas-liquid reactor from a hydrogen cyanide-containing gas, particularly the crude gas originating from a methane-ammonia (BMA) or Andrussow process, and acetone in the presence of a base. The aim of this invention is to overcome the disadvantages of existing methods for producing acetone-cyanhydrin. To achieve this, the gaseous phase removed from the reactor is purified from unreacted acetone and hydrogen cyanide using a gas purifier operated with a high-boiling solvent, specifically stabilized acetone-cyanhydrin, before being fed back into the gas-liquid reactor.
Another significant patent by Deusser is for a process for the preparation of 3-hydroxypropanal. This compound is prepared by reacting acrolein with water under pressure and in the presence of an ion exchange resin, while also adding a carboxylic acid to the reaction mixture. This method showcases her innovative approach to chemical synthesis.
