process for the production of perpropionsäurelösungen

摘要

In the production of perpropionic acid by reaction of hydrogen peroxide and propionic acid in an aqueous medium and in the presence of an acid catalyst, e.g. sulfuric acid, to produce the peracid and water, the danger of explosion is reduced by employing a molar ratio of hydrogen peroxide to propionic acid of less than 1.4:1, a temperature of up to 60 DEG C, and an initial hydrogen peroxide:water ratio of up to 1.2, and a catalyst concentration of 10-40% of weight.
