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
Trichloroisocyanuric acid Trichloroisocyanuric acid Trichloroisocyanuric acid is an organic compound with the formula (CClNO). It is used as an industrial disinfectant, bleaching agent and a reagent in organic synthesis. This white crystalline powder, which has a strong "chlorine odour," is sometimes sold in tablet or granule form for domestic and industrial use. Salts of trichloroisocyanuric acid are known as trichloroisocyanurates. Trichloroisocyanuric acid is prepared from cyanuric acid via a reaction with chlorine gas and sodium hydroxide. The compound is a disinfectant, algicide and bactericide mainly for swimming pools and dyestuffs, and is also used as a bleaching agent in the textile industry.
