Abstract

The process for producing granulated sodium percarbonate from aqueous solutions of calcined sodium carbonate and hydrogen peroxide comprises applying a mixture of aqueous solutions of calcined sodium carbonate and hydrogen peroxide simultaneously with an aqueous suspension of sodium percarbonate to crystal nuclei of sodium percarbonate. The suspension contains stabilizers. The mass ratio of the suspension to the mixture of aqueous reaction solutions which are applied to the crystal nuclei of sodium percarbonate is 0.25-4:1.
