Verfahren zur Herstellung von Peressigsäure

A peracetic acid product is produced by bringing together distillate, reaction medium and a substance partially neutralizing the acid catalyst. Production of a peracetic acid product comprises feeding hydrogen peroxide and acetic acid continuously into an aqueous reaction medium containing hydrogen peroxide, acetic acid, peracetic acid and an acid catalyst, in which medium the hydrogen peroxide and acetic acid react and form peracetic acid. A peracetic acid concentrated aqueous distillate is continuously distilled from the reaction medium. The distillate, the reaction medium and a substance partially neutralizing the acid catalyst are brought together. An independent claim is also included for the use of a base for stabilizing an acidic peracetic acid that contains another acid, stronger than the peracetic acid.
