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
Cyanuric acid Cyanuric acid Cyanuric acid or 1,3,5-triazine-2,4,6-triol is a chemical compound with the formula (CNOH). Like many industrially useful chemicals, this triazine has many synonyms. This white, odorless solid finds use as a precursor or a component of bleaches, disinfectants, and herbicides. In 1997, worldwide production was 160 million kilograms. Cyanuric acid is the cyclic trimer of the elusive species cyanic acid, HOCN. The two structures shown in the infobox are tautomers that readily interconvert. However, mixture with melamine forms melamine cyanurate, which locks cyanuric acid in the tri-keto tautomer and makes melamine cyanurate insoluble in water. The triol tautomer, which
