Title: David P. Brochu: Innovator in Phosphoric Acid Purification and Alkali Metal Phosphate Preparation
Introduction
David P. Brochu is a notable inventor based in Stroudsburg, PA (US). He has made significant contributions to the field of chemical engineering, particularly in the purification of phosphoric acid and the preparation of alkali metal phosphates. With a total of 2 patents to his name, Brochu's work has implications for various industrial applications.
Latest Patents
Brochu's latest patents include a process for purifying phosphoric acid and a method for preparing alkali metal phosphate. The first patent describes a process to purify a solution of phosphoric acid by removing transition metal impurities such as iron, chromium, and vanadium. In this innovative process, a solution of phosphoric acid in an organic solvent, which is substantially immiscible with water, is contacted with an aqueous solution of a salt of an alkali metal of phosphoric acid. The phosphoric acid recovered following this contacting contains a substantially lesser content of transition metal impurities.
The second patent focuses on the recovery of alkali metal phosphates from a water immiscible solvent solution of aqueous wet process phosphoric acid. This is achieved by neutralizing the acid with a basic alkali metal salt in a ratio of alkali metal to phosphorus of 1 to 3.5, forming at least the mono alkali metal phosphate. The solvent is then subjected to a water wash to recover entrained alkali metal phosphates, and the resulting aqueous solution and wash liquor containing the alkali metal salts are separated from the stripped solvent.
