SODIUM CARBONATE PERHYDRATE PROCESS

SODIUM CARBONATE PERHYDRATE PROCESS

A process is provided to react anhydrous car-bonate and hydrogen peroxide containing a hydroxy-alkylidene diphosphonic acid to produce 70% to 90% sodium carbonate perhydrate as a product. The pro-cess differs from the prior art in that reaction mixture is substantially dry at all times. The pro-duct...

Zusammenfassung:A process is provided to react anhydrous car-bonate and hydrogen peroxide containing a hydroxy-alkylidene diphosphonic acid to produce 70% to 90% sodium carbonate perhydrate as a product. The pro-cess differs from the prior art in that reaction mixture is substantially dry at all times. The pro-duct is stable even without added stabilizers.
