Latest Patents
Crowe's most recent innovations highlight his expertise in creating effective and efficient solutions within his industry. One of his notable patents, titled "Crosslinked, non-swellable ampholytic base resins," describes the creation of non-swelling, crosslinked bead forms of ampholytic base polymers. These innovative polymers are designed for use in chromatographic separation processes to isolate acids from various compounds. The preferred polymers are developed by modifying poly-2 or poly-4-vinylpyridine resins crosslinked with divinylbenzene.
Another significant patent from Crowe outlines "Processes for recovering citric acid." This invention presents preferred methods to extract citric acid from solutions, ensuring effective recovery in a purifiable form. One approach involves contacting a citric acid-containing medium with a solid-phase free base resin featuring tertiary amine groups for adsorption. The citric acid can then be desorbed using a stronger acid, resulting in a fraction that is substantially free from the stronger acid's contaminants. Additionally, another described method uses a divinylbenzene-crosslinked polymer with specific functional groups to adsorb citric acid, conducted at temperatures below approximately 40°C, leading to a high-quality recovery process.
