The potentially explosive reaction of hydrogen peroxide (H2O2) and copper chloride (CuCl2) was investigated. Pressure tests revealed that the reaction was strongly temperature - dependent and can easily undergo runaway reaction. Nevertheless, there was only a slight pressure increase at the low temperatures studied or when using low concentrations of CuCl2. Under the conditions generating the slight pressure increase, hypochlorite anions (ClO−) are generated and the acidity increases. As the reaction reaches completion, ClO− disappears, and the acidity decreases. Interestingly, the addition of phosphate buffer to maintain the weakly acid conditions led to a runaway reaction, and the use of basic ClO− promoted the exothermic reaction. Based on the results, acidity has a strong impact on the reaction behaviour.

CLO的影响- H中之间的反应和酸度2 ö 2和的CuCl 2
研究了过氧化氢(H 2 O 2)和氯化铜(CuCl 2)的潜在爆炸反应。压力测试表明,该反应强烈依赖于温度,并且很容易发生失控反应。然而,在所研究的低温下或使用低浓度的CuCl 2时,压力仅略有增加。在此条件下产生的轻微的压力增加,次氯酸盐阴离子(CLO - )产生和酸度增加。随着反应的完成达到,CLO -消失,酸度降低。有趣的是,加入磷酸盐缓冲液,以保持导致反应失控的弱酸条件下,和使用基本CLO的-促进放热反应。根据结果,酸度对反应行为有很大影响。
