    摘要: A process for producing sodium percarbonate which comprises reacting sodium carbonate with hydrogen peroxide in a working solution of sodium carbonate, hydrogen peroxide and water, said reaction being carried out in the presence of at least one N,N,N',N'-tetra(phosphonomethyl)diaminoalkane of the following formula ##STR1## wherein R is either ##STR2## and n is 0 or 1 to 4, and at least one salt selected from the group consisting of phosphates, silicates and magnesium salts.
