摘要
Water-soluble sulfonated organophosphorus compounds are purified by at least partially removing contaminating sulfite values therefrom, by decreasing the pH of a solution of such sulfonated organophosphorus compounds to a value of less than or equal to 4, and maintaining the pH of the solution at this value of 4 or less for such period of time as to reduce the weight concentration of sulfite in the solution to less than 100 ppm; the organophosphorus compounds thus purified are well suited for the two-phase cocatalysis of a wide variety of organic reactions.
