Abstract: The process for producing granular sodium percarbonate by fluidized bed buildup granulation comprises the spraying of an aqueous solution of hydrogen peroxide and of an aqueous solution of sodium carbonate with at least one multisubstance nozzle with external mixing into a fluidized bed comprising sodium percarbonate particles and simultaneously evaporating water, and is characterized in that the solution of sodium carbonate additionally comprises sodium carbonate and/or sodium percarbonate in suspended form and is passed through a dispersing apparatus for dispersion of solids before being fed to the multisubstance nozzle. The process allows the blockage of the multisubstance nozzle to be avoided and sodium percarbonate dust to be recycled from the offgas stream of the fluidized bed into the granulation.

Abstract: The invention relates to a process for the preparation of coated granular sodium percarbonate having a low TAM value. The preparation is carried out by fluidized-bed spray granulation at a temperature TG in the range from 45 to 75° C., and the coating is effected by the spray application of an aqueous solution containing at least one coating component in a fluidized bed at a temperature TU in the range from 35 to 100° C. According to the invention, a) after the fluidized-bed spray granulation but before the coating, drying is carried out at TNT of greater than TG, or b) the fluidized-bed granulation is carried out in at least two steps at TG1, TG2 . . . TGn, TG2 or TGn being higher than TG1, and drying being unnecessary if ? of the granulate have been formed at TG1, or c) drying takes place not after the granulation but after the coating, at TUNT, TUNT being at least 20° C. higher than TG.

Abstract: The invention relates to uncoated and/or coated sodium percarbonate with improved internal stability and storage stability; and, a process that provides uncoated and/or coated sodium percarbonate with improved internal stability and storage stability.
