Abstract

1377162 Sodium perborate monohydrate DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 4 Feb 1972 5240/72 Heading C1A A process for the production of abrasion resistant sodium perborate, monohydrate comprises treating the sodium perborate monohydrate at 20‹ to 90‹C. with 5% to 30% by wt. of water or another liquid which must not have an adverse effect on the active oxygen content or the dissolution time of the sodium perborate monohydrate and subsequently drying the sodium perborate monohydrate at a temperature which increases from 40‹ C. to 90‹C. Liquids which may be used, include hydrogen peroxide, sodium metaborate, methanol, ethanol, diethyl ether, polyvinyl alcohol and acetone preferably in the form of a 2% aqueous solution, except the sodium metaborate which is preferably used as a 10% aqueous solution.
