Procedure

Sodium percarbonate was prepared as follows: 127 g of 50% aqueous solution of hydrogen peroxide and 375 g of 30% aqueous solution of Na2CO3 were simultaneously added to a mother liquor containing 7.5 g of Na2CO3, 55 g of NaCl, 200 g of water and 10 to 1000 ppm of organic polymer (tables 1 and 2), for one hour at room temperature and by stirring at a rate of 142 rpm. The aqueous solution of hydrogen peroxide had been stabilized with an aqueous solution of sodium silicate (1.84 g of sodium silicate had been dissolved in 5 g of water).
