HCID 159762Sodium percarbonate

Conditions

Temperature: 20 °C

Procedure

Sodium percarbonate core particles were prepared in a continuous crystallization process using NaCl as salting out agent in a concentration of about 200 g/l. The crystallization reactor was filled with mother liquor at a temperature between 15 and 25° C. Solid sodium carbonate was added thereto until saturation is reached as well as a slight excess of a 60% wt aqueous hydrogen peroxide solution. The reactor was continuously stirred and cooled at a temperature of 15-25° C.
