The amount of carboxylic acid and a liquid inorganic acid catalyst (1% of the total solution weight) were placed in a vessel using a one-pot technique, following the procedures of epoxidation and the optimum reaction conditions set using acetic acid and the required amount of 34.5% aqueous H 2 O 2 solution in the presence of a catalytic amount of sulfuric acid. Over a half-hour period, the appropriate amount of H 2 O 2 was added dropwise. The synthesis was extended for another 4 hours.
