| Zusammenfassung: | The strong foaming which occurs during the reaction of a carboxylic acid, aqueous hydrogen peroxide and sulfuric acid as well as when a phlegmatizing additive is also employed is greatly reduced by adding a phosphane oxide. Besides a local gathering of alkali during the subsequent neutralization of the sulfuric acid is prevented and the flowability of the suspension obtained of the product is improved. Furthermore, the product obtained has remarkable storage stability. |
