Abstract

A process for producing sodium perborate monohydrate agglomerates or granules in which primary particles of sodium perborate monohydrate produced from sodium perborate tetrahydrate by a dehydration process are subjected to compacting pressing agglomeration, and the resulting agglomerates are subsequently comminuted to granules.
