摘　　要：在氯化铵溶液体系中,以氧化镁,过氧化氢为原料,制备高纯过氧化镁。研究表明采用氧化镁活性大于100,氯化铵/氧化镁不小于10%,过氧化氢:氧化镁不小于4∶1,反应温度大于40℃情况下,反应时间不小于30 min,可制备出纯度大于90%的过氧化镁。In ammonium chloride solution,magnesium oxide and hydrogen peroxide as raw material,high purity magnesium peroxide was prepared.The results showed that using magnesium oxide activity was greater than 100,ammonium chloride and magnesium oxide was not less than 10%,hydrogen peroxide to magnesium oxide was not less than 4：1,the reaction temperature was higher than 40 ℃,and the reaction time was not less than 30 min,with magnesium peroxide purity above 90%.
