Production of Sodium Perborate Monohydrate by Microwave Heating

In this work, sodium perborate tetrahydrate was dehydrated to perborate a monohydrate by using 350 W, 2450 MHz microwave radiation energy. The dehydration was achieved in 25 min without melting. In this dehydration process, the heating time and the temperature were easily controlled by microwave ene...

Zusammenfassung:In this work, sodium perborate tetrahydrate was dehydrated to perborate a monohydrate by using 350 W, 2450 MHz microwave radiation energy. The dehydration was achieved in 25 min without melting. In this dehydration process, the heating time and the temperature were easily controlled by microwave energy. The product obtained was in powder form containing 15.2−15.6 wt % active oxygen and 95−97 wt % NaBO3·H2O. In addition, the product was not contaminated by impurities.
