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
3-Nitrobenzoic acid methemoglobin, sensitisation, irritation, and corneal damage. 3-Nitrobenzoic acid 3-Nitrobenzoic acid is an organic compound with the formula CH(NO)COH. It is an aromatic compound and under standard conditions, it is an off-white solid. The two substituents are in a meta position with respect to each other, giving the alternative name of m-Nitrobenzoic acid. This compound can be useful as it is a precursor to 3-aminobenzoic acid, which is used to prepare some dyes. It is prepared by nitration of benzoic acid at low temperatures. Both 2-Nitrobenzoic acid and 4-Nitrobenzoic acid are produced as side products, with yields of approximately 20% and
