Peracetic acid Peracetic acid Peracetic acid (also known as peroxyacetic acid, or PAA), is an organic compound with the formula CHCOH. This organic peroxide is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid. It can be highly corrosive. Peracetic acid is a weaker acid than the parent acetic acid, with a p"K" of 8.2. Peracetic acid is produced industrially by the autoxidation of acetaldehyde: It forms upon treatment of acetic acid with hydrogen peroxide with a strong acid catalyst: As an alternative, acetyl chloride and acetic anhydride can be used to generate a solution of the acid with
Xenic acid Xenic acid Xenic acid is a noble gas compound formed by the dissolution of xenon trioxide in water. Its chemical formula is HXeO. It is a very powerful oxidizing agent, and its decomposition is dangerous as it liberates a large amount of gaseous products: xenon, oxygen, and ozone. However, this feature is also what makes xenic acid practically useful in syntheses: there is no chance of introducing impurities to the oxidation products, as all the byproducts can be trivially evaporated. Its existence was hypothesized by Linus Pauling in 1933. Xenic acid has been used as an oxidizing agent in organic
