1. Introduction of Peroxyacetic acid

Peroxyacetic acid is an organic compound with the cas number of 79-21-0. Peroxyacetic acid is a weaker acid than the parent acetic acid. It is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid. It can be highly corrosive.


2. Basic Information of Peroxyacetic acid

Peracetic acid is a weaker acid than the parent acetic acid, with a pKa of 8.2. Peracetic acid is always sold in solution with acetic acid and hydrogen peroxide to maintain the stability of the peracid. The concentration of the acid as the active ingredient can vary.

1). Properties

Stability: Stable in dilute aqueous solutions.
Specific gravity: 1.0375 at 20 deg C/4 ℃.


2) Preparation

Peracetic acid is produced industrially by the autoxidation of acetaldehyde:[1]

It forms upon treatment of acetic acid with hydrogen peroxide, the equilibrium constant being 0.37 at room temperature:

H2O2 + CH3CO2H → CH3CO3H + H2O
As an alternative, acetyl chloride and acetic anhydride can be used to generate a solution of the acid with lower water content.


3) use

Peracetic acid is generated in situ during the some laundry detergents. This route involves the reaction of tetraacetylethylenediamine (TAED) in the presence of an alkaline hydrogen peroxide solution. The peracetic acid is a more effective bleaching agent than hydrogen peroxide itself. PAA is also formed naturally in the environment through a series of photochemical reactions involving formaldehyde and photo-oxidant radicals.
