摘要： @ A method and composition for preventing corrosion is disclosed. The method involves forming a coating of from about 2 to 15 mils thick on a surface, with a composition comprising an over-based alkaline earth organic sulfonate salt, a drying oil, a copper or rare earth metal drier, a zinc metal drier, a naphthenic or straight chain paraffinic oil, and petrolatum, and curing the coating. Preferably, the composition will include a copper metal drier, a zinc metal drier, and a rare earth metal drier. The method and composition are particularly useful for metal surfaces which contact sea water.

摘要： This invention relates to a process for reducing the population of bacteria in aqueous systems which comprises co-treating said aqeous system with 2,2-dibromo-3-nitrilopropionamide and chlorine dioxide under the conditions specified herein. By co-treating an aqueous system with both 2,2-dibromo-3-nitrilopropionamide and chlorine dioxide, one can achieve a more effective biocidal effect with the same amount of biocide than if either the 2,2-dibromo-3-nitriloprionamide or chlorine dioxide are used separately.
