Title: The Innovations of Fritz Brunnmueller

Introduction

Fritz Brunnmueller is a notable inventor based in Limburgerhof, Germany. He has made significant contributions to the field of chemistry, particularly in the preparation and handling of hydrogen cyanide. With a total of 10 patents to his name, Brunnmueller's work has had a considerable impact on industrial processes.

Latest Patents

One of his latest patents involves the preparation of reaction products of hydrogen cyanide. This process allows for the production of hydrogen cyanide through pyrolysis at temperatures ranging from 250°C to 650°C. The method ensures that large amounts of hydrogen cyanide are handled safely by cooling it to a temperature between 200°C and -10°C, along with other pyrolysis products. The hydrogen cyanide is then subjected to a chemisorption reaction with a base or a carbonyl compound, leading to the formation of valuable reaction products. Another significant patent focuses on the thermolytic cleavage of formamide to produce hydrocyanic acid and water. This process, which utilizes alumina or alumina/silica moldings, achieves high selectivity for HCN and a high conversion rate of formamide.
