Abstract
Abrasion resistant sodium perborate monohydrate is prepared by treating sodium perborate monohydrate with at least 5% of water at a temperature of 20.degree. - 90.degree. C. in a moistening unit and then drying at a temperature beginning at 40.degree. C. and increasing to a maximum of 90.degree. C.
Claims13
A process for the production of abrasion resistant sodium perborate monohydrate comprising treating preformed sodium perborate monohydrate in a moistening unit by adding water in an amount of 5 to 30 weight % of the sodium perborate monohydrate at a temperature of 20.degree.-90.degree. C. and then drying the monohydrate at a temperature beginning at 40.degree. C. and increasing to a maximum of 90.degree. C.
