Abstract: A process is provided for the safe storage of sodium percarbonate in a bulk container that is substantially closed to the ambient atmosphere. A temperature is measured at at least one position inside the sodium percarbonate stored in bulk and, with an increase in temperature within the range of 0.5 to 10° C. per day, in particular 1 to 5° C. per day, dry air is passed periodically or continuously through the bulk material until the increase in temperature has fallen to a value of less than 1° C. per day in particular less than 0.5° C. per day.

Abstract: Fluidized-bed coating of peroxy compounds, especially sodium percarbonate for use in detergent and bleaching products. Production of coated peroxy compounds by fluidized-bed coating comprises spraying an aqueous coating solution onto particles of the peroxy compound in a fluidized-bed chamber and drying the coating by means of a fluidizing gas injected through a radial distributor plate at a fluidized bed temperature of 30-70 degrees C, where the fluidizing gas emerges (upwards) from openings in the distributor plate at an angle of less than 35 degrees to the horizontal and the coating solution emerges (downwards) from spray nozzles at the same angle.

Abstract: The method for production of granular sodium percarbonate by fluid bed fo rmation granulation, includes spraying an aqueous solution of hydrogen perox ide and an aqueous solution of sodium carbonate by means of at least one mul ti-component nozzle with external mixing in a fluid bed, containing sodium p ercarbonate particles with simultaneous evaporation of water and is characte rised in that the solution of sodium carbonate contains additional sodium ca rbonate and/or sodium percarbonate in suspended form which is supplied to a dispersion device for dispersing solids before introduction to the multicomp onent nozzles. The method permits the avoidance of blockages in the multicom ponent nozzles and recycling of sodium percarbonate dust from the exhaust ga ses of the fluid bed to the granulation.
