Latest Patents

Kimitaka Okamoto holds a patent for a method of preparing alkali metal fluoroalkylsulfonates of high purity. This patent describes a process for creating fluoroalkylsulfonate RfSO.sub.3 M, where Rf is a perfluoroalkyl group with no more than six carbon atoms and M represents an alkali metal. The method involves a neutralization reaction between fluoroalkylsulfonic acid RfSO.sub.3 H and an alkali metal carbonate or hydroxide. The reaction is conducted under acidic conditions, ensuring that the pH of the reaction liquid remains below 6, and preferably not higher than 3. By maintaining an acidic environment, the resulting RfSO.sub.3 M exhibits low concentrations of anionic impurities, such as free fluorine, free chlorine, and carbonate radicals, while also minimizing moisture absorbency.
