Abstract

Abstract PURPOSE: To produce foamable sodium percarbonate which violently foams in water and shows superior solubility, by heat treating sodium percarbonate under specific conditions and cooling it. CONSTITUTION: Sodium percarbonate is heat treated at 110W135°C for 7W30min and blown with cold air within 10min to be rapidly cooled to 90°C or below. EFFECT: Oxygen loss due to high temp. long-time retention is minimized and hence foamable sodium percarbonate with increased foaming quantity is obtd. COPYRIGHT: (C)1979,JPO&Japio
