CALCIUM PERBORATE Usage And Synthesis
Uses
Calcium perborate has been used as an oxidizing and teeth-whitening agent in dentistry and in some applications in polyolefin polymer preparation.
Preparation
Calcium perborate, CaB2O6, has the CAS number of
54630-47-6. Its Lewis formula is shown in Fig. 6.23.
It has been prepared by the reaction:
CaCl2 (aq) + Na2B4O5 +H2O2→Ca(BO3)2·2H2O
+ 2NaCl
This mixture was stirred, and the temperature was
maintained at 20-25 °C. The solids were then filtered
out, and the filter cake was reslurried with water and
filtered again. Finally, the solids were dried overnight
in a vacuum oven at 50 °C. The product thus obtained
was a calcium perborate, Ca(BO3)2, containing the
equivalent of 27.9% calcium oxide [CaO] and 10.0%
active oxygen [O].
