| Abstract: | Calcium peroxide was synthesized from calcium oxide and hydrogen peroxide as raw materials. The influences of some factors such as the reaction temperature, the reaction time, the superfluous coeffi- cient of hydrogen peroxide, the amount of HC1, etc. to the yield and purity of calcium peroxide was investi- gated. Result show that the optimum process conditions were obtained as follows： reaction temperature 2 ℃, reaction time 1 h, mole ratio of calcium oxide to hydrogen peroxide 1 ： 1.15, amount of HCI （ 1 ： 1 ） 0.75 mL. The yield and purity of Ca02 are 61.41% and 67.13% ,respectively. |
