Title: The Innovations of William R. Davie
Introduction
William R. Davie is an accomplished inventor based in Hopewell Township, PA (US). He holds a total of 3 patents that showcase his contributions to the field of chemical engineering. His work primarily focuses on the removal of iron compounds from organic process streams and the minimization of discoloration in maleic anhydride.
Latest Patents
One of Davie's latest patents addresses the removal of iron compounds from organic process streams. This innovative method utilizes weakly basic ion exchange resins to effectively eliminate iron compounds in anhydrous or substantially anhydrous organic systems, such as phenolic process streams. The resins can exist as weak salts or protonated amine carboxylic acids. Notably, the active site of these resins forms a complex with the entire iron compound molecule, rather than functioning in a conventional ion exchange manner. This complex can be regenerated in an aqueous system, demonstrating the versatility of the invention.
Another significant patent by Davie focuses on minimizing the discoloration of maleic anhydride. This process involves passing maleic anhydride in molten or dissolved form through a bed of cation exchange resin. Following this, a small amount of 3,3'-thiodipropionitrile is added to the maleic anhydride to further reduce discoloration.
