Abstract:
1. A method for the rapid dilution of an aqueous peracid solution comprising introducing an aqueous diluent other than water alone into an aqueous peracid solution containing an organic peroxycarboxylic acid, hydrogen peroxide, corresponding carboxylic acid and water which are in substantial equilibrium with each other, to yield a diluted aqueous peracid solution having a peracid concentration lower than the initial concentration; the introduced aqueous diluent being selected from the group consisting of hydrogen peroxide and water; corresponding carboxylic acid and water; and hydrogen peroxide, corresponding carboxylic acid and water; the introduced diluent components being introduced concurrently into the aqueous peracid solution to be diluted; and the amount of introduced diluent components being adjusted to provide a diluted aqueous peracid solution containing peroxycarboxylic acid, hydrogen peroxide, corresponding carboxylic acid and water already in substantial equilibrium with each other upon completion of the diluent introduction.
