Abstract
Dilute, aqueous solutions of lower organic peracids are rapidly prepared by reacting the anhydride of the organic acid corresponding to the peracid with concentrated hydrogen peroxide to form an aqueous peracid mixture. Before equilibrium is attained, the mixture is diluted with water and hydrogen peroxide to produce an equilibrium mixture of organic acid, peracid, hydrogen peroxide, and water. The process can be carried out in 60 minutes or less and can be run either as a batch or as a continuous process.
