【摘要】 从反应热力学以及实验设计比较两方面出发,研究氨水对CaCl₂和H₂O₂反应制备CaO₂的影响。发现氨水用量与过氧化钙产量相关,当NH₃/Ca²⁺摩尔比小于2时,CaCl₂无法反应完全;当NH₃/Ca²⁺摩尔比为2时,过氧化钙产量增加,且无过多氢氧化钙杂质生成,较为符合制备反应的实验设计。更多还原

【Abstract】 The ammonia usage in CaO₂ preparation through CaCl₂ and H₂O₂ was investigated by the reaction thermodynamics and the designed experiments. The results show that calcium peroxide production is related with the ammonia usage. When the molar ratio of NH₃/Ca²⁺ is less than 2, CaCl₂ could not converse completely. With the molar ratio of NH₃/Ca²⁺ reaching 2,high amount of CaO₂ and small amount of Ca（OH）2 were achieved. This molar ratio of 2 is suggested to be reasonable in the CaO₂ preparation design.更多还原
