摘 要:研究了氢氧化钙-氯化铵-双氧水法生产过氧化钙的工艺过程和影响因素。通过单因素实验,得到制备过氧化钙的最佳工艺条件为反应温度26℃、反应时间35 min、稳定剂偏硅酸钠用量14%、双氧水浓度15%、氢氧化钙过量50%、氯化铵用量n(NH4Cl)∶n(Ca(OH)2)=1.5。In this paper,calcium peroxide was produced by calcium hydroxide and ammonium chloride with hydrogen perox-ide.The factors of influencing calcium peroxide were investigated.The optimum conditions were determined by the mono-factor experiments.The results showed that reaction time was 35 min,reaction temperature was 26 ℃,stabilizer dosage was 14%,hydrogen peroxide concentration was 9%,excessive amount of calcium hydroxide was 50%,excessive amount of ammonium chloride was n(NH4Cl)∶n(Ca(OH)2)=1.5.
