Abstract

Procedure for the Preparation of Abrasion Resistant Sodium Percarbonate, Coarse Grain, Stable and Flowable, by Reaction of a Hydrogen Peroxide Solution, Containing a Magnesium Salt, with a Sodium Carbonate Solution or Suspension at temperatures from 10 to 30ºC, possibly in the presence of phosphates, characterized in that 2 to 8 g/liter, preferably 3 to 6 g/l of sodium hexametaphosphate or sodium polyacrylate, are added to the sodium carbonate solution or suspension, since 3 to 10 g/l, preferably 3 to 7 g/l of magnesium ions, preferably in the form of magnesium salts of strong acids are added to the hydrogen peroxide solution, optionally subjected to saline precipitation with common salt, the resulting crystals They are separated from the mother liquor, and this, preferably after adding an additional amount of common salt, is returned to the process to dissolve or suspend sodium carbonate.
