Abstract
1. Process for the manufacture of sodium perborate monohydrate by dehydration of sodium perborate tetrahydrate by heating under reduced pressure, characterized in that this dehydration is performed at an absolute pressure which is maintained between 0.03 and 0.13 bar at a temperature of the mass which is to be dehydrated not exceeding 70 degrees C, without any gas stream being allowed to enter the dehydration zone.
