Latest Patents

Johnson's latest patents include innovative methods for controlling biofouling in cooling towers. One patent discloses a method for inhibiting microorganisms and controlling biofouling at alkaline pH and/or high water hardness using specific alkylthioalkylamines, such as n-decylthioethylamine. Another patent addresses the reduced volatility of halogenated phenols in wood. This method involves treating wood with organic compounds that have cationic groups, which can form water-insoluble halogenated phenoxide salts. For instance, contacting pentachlorophenol-treated wood with quaternary ammonium compounds, like didecyldimethylammonium chloride, significantly reduces the release of pentachlorophenol vapors from the wood.
