• 使用

  Calcium perborate has been used as an oxidizing and teeth-whitening agent in dentistry and in some applications in polyolefin polymer preparation.

• 製造方法

  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].
