Abstract

1. Process for continuous production of sodium perborate monohydrate by dehydration of sodium perborate tetrahydrate in only one step in a bed fluidized by means of a current of hot air, characterized in that the temperature of the air is between 100 C and 180 C when it enters the fluidization zone and that, in the said zone, the temperature is between the fusion temperature of sodium perborate tetrahydrate and 80 C and the relative humidity is below 40% and at least 10%.
