Title: The Innovative Contributions of Donald McKinney
Introduction
Donald McKinney is a notable inventor based in Howell, NJ (US), recognized for his significant contributions to the field of chemical processes. With a total of 2 patents, McKinney has developed innovative methods that enhance the efficiency and environmental sustainability of chemical manufacturing.
Latest Patents
One of McKinney's latest patents is focused on the recovery of iodide from chemical process wastewater. This process involves loading wastewater containing iodide onto a strongly basic anion-exchange resin in free-base form. The iodide is then eluted from the resin using aqueous strong acid, such as hydrochloric acid. Following this, the iodide-rich cuts are loaded onto a weakly basic anion-exchange resin, and the iodide is eluted with aqueous base, like sodium hydroxide. The recovered iodide typically possesses sufficient purity for reuse in chemical processes.
Another significant patent by McKinney details a process for removing waste phosphorus-containing materials, alendronate, and its byproducts from crude mother liquors in the synthesis of alendronate sodium. The process begins with the addition of calcium chloride to the crude mother liquors, followed by calcium oxide to precipitate the phosphorus-containing materials. The mixture is then neutralized to about pH 7 to complete the precipitation. This method effectively removes substantially all of the alendronate sodium active ingredient from the precipitate, allowing for environmentally responsible disposal or reclamation of usable phosphorus.
