Peracetic acid was prepared according to a reported method, that glacial acetic acid (0.5 mol) was mixed with concentrated sulfuric acid (0.375 mol) and the resulting mixture was allowed to cool to reach 0◦C. This cold acids mixture was then added, dropwise to hydrogen peroxide solution, so that the final reaction volume does not exceed 100 ml and at the end of addition, the system tem-perature was raised to 25◦C and maintained at this temperature for 90 min. The progress in the reaction of peracid formation was monitored by withdrawing samples from the reaction medium at different time intervals and estimating the amounts of consumed hydrogen peroxide and formed peracid throughout the reaction duration.
