Description

  

  Verfahren zur Herstellung von     Natriumperborat    mit maximalem haltbaren       Sauerstoffgehalt.       In der deutschen Patentschrift Nr. 318219  ist ein Verfahren 'zur Herstellung von drei       Perboraten    mit     10'/o        bezw.    21,7/o     bezw.    28,4%  an aktivem Sauerstoff beschrieben. Es hat  sich herausgestellt, dass die ersten beiden Per  borate praktisch haltbar sind und innerhalb  eines Jahres nur ein bis zwei Prozent     ihres     Gehaltes an aktivem Sauerstoff verlieren.  Das     Perborat    mit 28,4 % verliert innerhalb  eines Jahres mehrere Prozente seines Gehaltes  und geht in dieser Zeit auf 21,5 % zurück.  



  Gegenstand vorliegender Erfindung ist  nun ein Verfahren zur Herstellung von       Natriumperborat    mit maximalem haltbaren  Sauerstoffgehalt, gemäss welchem Verfahren  man bei der Behandlung von N'atriummeta-    borgt mit Wasserstoffsuperoxyd nach einem  der bekannten Verfahren nicht wesentlich  über .23 % an aktivem Sauerstoff einführt.  Ein nach diesem Verfahren hergestelltes Na  triumperborat ist praktisch haltbar.



  Process for the production of sodium perborate with maximum stable oxygen content. In the German patent specification No. 318219 is a process 'for the production of three perborates with 10' / o respectively. 21.7 / o or 28.4% active oxygen is described. It has been found that the first two perborates are practically stable and only lose one to two percent of their active oxygen content within a year. The perborate at 28.4% loses several percent of its salary within a year and falls to 21.5% during this time.



  The present invention now relates to a process for the production of sodium perborate with a maximum stable oxygen content, according to which process one does not introduce substantially more than 23% of active oxygen in the treatment of sodium metal boron with hydrogen peroxide according to one of the known processes. A sodium perborate produced by this process is practically stable.
