Claims10
A method for producing equilibrium peracetic acid by reacting acetic acid with an aqueous hydrogen peroxide solution, having a content of 25 to 60% by weight hydrogen peroxide, in an aqueous reaction mixture, wherein the reaction is carried out in the presence of methanesulphonic acid as catalyst.
An equilibrium peracetic acid comprising 2 to 24% by weight peroxyacetic acid, hydrogen peroxide, acetic acid, water and methanesulphonic acid, said equilibrium peracetic acetic being less corrosive than an equilibrium peracetic acid comprising sulfuric acid instead of methanesulphonic acid.
