ABSTRACT:
Process for the continuous preparation of organic solutions of percarboxylic acids by reaction of aqueous hydrogen peroxide with the corresponding carboxylic acid in the presence of an acid, water-soluble catalyst, extraction of the resulting reaction mixture with an organic solvent and recycle of the raffinate, containing hydrogen peroxide, after reconcentration by the removal of water by distillation into the reaction. The raffinate is fed, together with the whole of that amount of hydrogen peroxide which essentially to the consumption of hydrogen peroxide in the reaction or with a part thereof, into the distillation for the removal of water. The amount of water which essentially corresponds to the sum of the water of reaction formed during the reaction and the water introduced into the process with the feed products is distilled off under reduced pressure. The sump product, thus obtainable, from the distillation is recycled into the reaction.
