| titleOfInvention | Process for preparing granular phase and sodium carbonate by fluidised bed spray granulation and granular phase and sodium carbonate prepared by the method |
| abstract | The present invention relates to a process for the preparation of granular and sodium carbonate having a low TAM value by fluidized bed granulation. In accordance with the present invention, during fluidized bed granulation, from 50 to 2000 ppm of magnesium compounds, in particular from 100 to 1000 ppm, and / or hydroxycarboxylic acids, aminophosphonic acids, phosphonic carboxylic acids, hydroxyphosphonic acids and their alkali salts, ammonium salts or magnesium 50 to 2000 ppm, in particular 200 to 1000 ppm, of a complexing agent from a salt are added as an aqueous solution of sodium carbonate and / or aqueous H 2 O 2 as a stabilizer. Preferably, a combination of magnesium compound of 100 to 1000 ppm Mg + 2 with 0.1 to 1% by weight, especially 0.1 to 0.5% by weight of water glass is used. In this way, a granular material with a TAM value of 6 μW / g or less and a low dissolution time can be obtained.n n n Fluidized bed granulation, sodium percarbonate granular material, magnesium compound, chelating complexing agent, TAM value |
