Abstract
Superoxidized sodium perborate with an active oxygen content of more than 16 wt. % and a specially adapted process for its preparation.
Claims9
Sodium perborate with an active oxygen content of more than 16% by weight, characterized by the following characteristics of the IR spectrum (compressed KBr):
- discrete bands within the range of approximately 3430, 2820, 1640, and 1060 cm.sup.-1 ;
- missing individual bands at 850-870 cm.sup.-1 ;
- and
- permeability ratio D.sub.1060 :D.sub.3430 <1.0, where D represents the permeability at the corresponding wavelength measured in percent.
