Latest Patents
One of his latest patents is titled "Crosslinked, non-swellable ampholytic base resins." This invention describes non-swelling, crosslinked, bead forms of ampholytic base polymers that can be utilized in the chromatographic-type separation of acids from other compounds. The preferred polymers are prepared by modifying a poly-2 or poly-4-vinylpyridine resin crosslinked with divinylbenzene. Another significant patent is focused on "Processes for producing citrate esters." This patent outlines methods for producing citrate esters in an economical fashion. The esters are prepared by esterification of a citric acid-containing fermentation broth that has been treated to remove cations and optionally other impurities, while still containing sugars. Additionally, esters can be produced by reacting an impure aqueous citric acid source with an alcohol, resulting in a heterogeneous aqueous/organic reacted mixture. This process allows for the convenient separation of impurities from the product, avoiding the energy-intensive distillation of water from the reaction medium.
