Abstract

Sodium percarbonate of the formula 2 Na2CO3<.>3 H2O2 can be produced by fluidised-bed spray granulation by spraying an aqueous solution of sodium carbonate and a hydrogen peroxide solution on sodium percarbonate seeds and evaporating water. The previously necessary use of phosphorus-containing crystallisation inhibitor to prevent blockages and incrustations in and on the nozzle can be avoided by the invention if the solutions are sprayed using a single three-substance pulverisation nozzle with the external mixing of the solutions.
