Peracetic acid was prepared according to a reported method[57], that glacial acetic acid (0.5 mol) was mixed with concentratedsulfuric acid (0.375 mol) and the resulting mixture was allowed tocool to reach 0◦C. This cold acids mixture was then added, dropwiseto hydrogen peroxide solution, so that the final reaction volumedoes not exceed 100 ml and at the end of addition, the system tem-perature was raised to 25◦C and maintained at this temperaturefor 90 min. The progress in the reaction of peracid formation wasmonitored by withdrawing samples from the reaction medium atdifferent time intervals and estimating the amounts of consumedhydrogen peroxide and formed peracid throughout the reactionduration.
