Abstract

A process for the preparation of a high porosity and flowing sodium perborate with an apparent specific gravity between 0.25 and 0.45 kg/l by reaction of a solution of sodium metaborate with hydrogen peroxide, characterized in that while stirring a a temperature between 10 and 15º C. an aqueous solution of sodium metaborate is added to an aqueous solution of hydrogen peroxide until the beginning of crystallization, and then the addition of both sodium metaborate and hydrogen peroxide is continued, the ratio must be maintained molar hydrogen peroxide to sodium metaborate between 1.1 and 1.8, and finally, at the desired conclusion of the precipitation, hydrogen peroxide present in excess reacts with additional sodium metaborate.
