Abstract: The spray drying of a solution containing hydrogen peroxide and sodium metaborate to obtain primary particles which are immediately conveyed after leaving the drying zone to a granulating device and are then granulated in the presence of free and/or perborate water of crystallization. The granulated materials are dried, if necessary. The generally amorphous primary particles are converted into granulated materials with at least partially crystalline structure and significantly improved shelf life. The work is performed with advantage in a spray dryer with integrated fluid bed or in a compressing granulating device. The method is suitable for preparing perborate granulated materials with over 10% by wt., especially perborate monohydrate granular materials with 14-16% by wt. active oxygen.

Abstract: A method for the production of granular sodium perborate tetrahydrate is disclosed herein. The method includes the steps of adding 0.3-5% by weight of a sodium salt or a potassium salt of a polymeric carboxylic acid to powdered perborate tetrahydrate, softening the mixture by heating under pressure to form a plastically deformable mass, deforming the plastically deformable mass into thin strands by pressing, and comminuting the strands into granular form. The perborate tetrahydrate may be de-watered to produce granular perborate monohydrate. The final granular products exhibit high abrasion resistance and are preferably used in washing and cleaning agents.

Abstract: The invention relates to a process for the production of granular sodium perborate monohydrate having good mechanical strength. The process is characterized in that sodium silicate having an SiO.sub.2 /Na.sub.2 O molar ratio comprised within the range of from 0.4 to 2.0 is added to granular sodium perborate tetrahydrate while this is being kept in movement and the so processed perborate tetrahydrate is dried until perborate monohydrate is obtained.
