Process for stabilization of sodium percarbonate |
摘要 |
Sodium percarbonate can be stabilized by treatment with an aqueous solution of an alkaline earth metal salt to form a thin layer of an alkaline earth metal carbonate on the surface. The resulting sodium percarbonate is improved its respect to the nonhygroscopic property, while maintaining the same solubility in water and effective oxygen content as initially.
