Abstract: Method of storing sodium perborate monohydrate granules at elevated surrounding temperature of between 10.degree. and 65.degree. C., according to which the granules are stored in bulk in a closed enclosure proofed against the surrounding atmosphere, into which is introduced a slow flow of dry air which is forced to pass through the mass of the granules, the air flow escaping to the atmosphere through a small opening made in the part of the enclosure away from that where the said flow is introduced.The process applies to the transport of sodium perborate monohydrate in a tank truck.

Abstract: Process for producing sodium perborate monohydrate by dehydration of sodium perborate tetrahydrate using a current of air which is initially damp in a first phase of dehydration then dry in a second phase of dehydration.The sodium perborate monohydrate obtained can be used in washing powders for textiles.
