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
Glutaconic acid can be used to make it: the "trans" form isomerizes under the reaction conditions. Glutaric, 3-hydroxyglutaric, and glutaconic acids are structurally related metabolites. In glutaric aciduria type 1, glutaconic acid accumulates, resulting in brain damage. Glutaconic acid "trans"-Glutaconic acid is an organic compound with formula HOCCH=CHCHCOH. This dicarboxylic acid exists as a colorless solid and is related to the saturated chemical glutaric acid, HOCC(CH)COH. Esters and salts of glutaconic acid are called glutaconates. The geometric isomer, "cis"-glutaconic acid, has a noticeably lower melting point (130–132 °C). It can be prepared by bromination of levulinic acid followed by treatment of the
