Abstract
PURPOSE: To obtain a granular product with low hygroscopicity by reacting an aqueous hydrogen peroxide soln. with sodium carbonate in the presence of a specified amount of a silicate and an Mg salt and granulating the resulting caky sodium percarbonate with an aqueous hydrogen peroxide soln.
CONSTITUTION: When an aqueous hydrogen peroxide soln. is reacted with sodium carbonate to manufacture sodium percarbonate, they are reacted in the presence of a silicate such as sodium metasilicate or sodium orthosilicate in an amount of 0.14W 2.8g as Si to 1kg produced sodium percarbonate and an Mg salt such as magnesium sulfate or magnesium chloride in an amount of 0.024W0.72g as Mg. Produced sodium percarbonte is separated, and to 75W92pts.wt. as pure component of the separated caky sodium percarbonate is added 25W8pts.wt. aqueous hydrogen peroxide soln. having 1.5W10wt% concn. By granulating the mixture of tableting or other pressurizing method, the titled sodium percarbonate is obtd.
