Abstract (en)
[origin: WO2007012451A1] The invention relates to a method for the production of bleaching catalyst granules, containing a bleaching catalyst, an acidic polymer, a support material and optionally further adjuncts, characterised in that a fluid bed is formed from the support material in a fluidised bed apparatus, an aqueous solution or dispersion is added to the fluid bed, containing the bleaching catalyst, the acidic polymer, and optionally the further adjuncts which is then granulated and dried. The method is particularly suitable for bleaching catalysts of formula (1), where R, R<SUP>1</SUP>, R<SUP>2</SUP>, R<SUP>3</SUP> and X have the meanings given in the description.
