ABSTRACT:
Process of preparing substantially anhydrous solutions of percarboxylic acids which comprises reacting hydrogen peroxide contained in an aqueous solution with a water miscible carboxylic acid in the presence of a catalyst and an azeotropic organic solvent, continuously removing the water added with the hydrogen peroxide and formed during the reaction by azeotropic distillation by way of a distillation column, and continuously injecting water into the top of the distillation column during at least the major portion of the reaction time, the quantity of the injected water being less than the quantity of the water removed by azeotrope distillation.
