Hydrogen Peroxide → 10-Sulfoperoxystearic acid

Participants

Reaction Steps

To a 2.0 g mixture of 9 or 10-Sulfostearic acid was added 2.0 g of 50% H2O2. The mixture was stirred at room temperature until all the solid was dissolved. Then, 2.0 g of 75% H3PO4 was added, and the resulting solution was stirred at room temperature overnight. No attempt was made to isolate the pure 9 or 10-sulfoperoxystearic acid from solution. 13C NMR (D2O) of the solution showed a peracid peak (COOOH) at 174 ppm and the parent the carboxylic acid peak at 178 ppm. The iodometric titration (QA™-202) indicated 18.96% of sulfoperoxystearic acid.
