Abstract

In order to safely prepare peracetic acid in an organic solvent, the bottom is maintained in a certain stationary state during the preparation of aqueous peracetic acid, whereupon the vapor current of peracetic acid, acetic acid and water is absorbed with an organic phosphate with 3-30 carbon atoms. The solution obtained in this manner can be transferred by means of desorption with a low-boiling compound, e.g. an alkyl ester, into this lower-boiling solvent.
