Title: The Innovations of Andrew D Broome
Introduction
Andrew D Broome is a notable inventor based in Warrington, GB. He has made significant contributions to the field of chemistry, particularly in the manufacture of arsenic compounds. With a total of 3 patents to his name, Broome's work has implications for both industrial processes and environmental safety.
Latest Patents
One of Broome's latest patents focuses on the manufacture of arsenic acid. This process involves the oxidation of arsenic trioxide with hydrogen peroxide, which can be hazardous, especially when producing concentrated solutions. The method addresses issues such as the wasteful decomposition of hydrogen peroxide and the formation of localized hot spots during the reaction. By introducing reagents with agitation and maintaining a controlled temperature, the process can effectively utilize low-grade arsenic trioxide as a reagent.
Another significant patent by Broome is related to wood preservative compositions. He developed a copper arsenate composition suitable for incorporation into a copper/chrome/arsenic wood preservative. This is achieved by reacting copper metal with a source of 5-valent arsenic, such as arsenic acid, under the oxidizing influence of hydrogen peroxide. The composition allows for a consistent arsenic to copper ratio, which is essential for the final wood preservative product.
