Abstract:
A process for the production of a mixed percarbonate/sodium bicarbonate compound, said process comprising:reacting a reaction mixture of sodium bicarbonate with a sufficient quantity of an aqueous hydrogen peroxide solution to convert 40 to 60 mole-% of the sodium bicarbonate to sodium percarbonate, wherein said reacting is carried out under heating to a temperature of at least 50.degree. C., and a mixed sodium percarbonate/sodium bicarbonate compound is formed, anddrying the reaction mixture to recover the mixed sodium percarbonate/sodium bicarbonate compound,wherein said mixed sodium percarbonate/sodium bicarbonate compound comprises about 60-40 mol % sodium bicarbonate and about 40-60 mol % sodium percarbonate.
