双氧水自热分解反应容易引发反应失控。利用泄放小试模拟实验装置，研究了碱性环境下，质量分数10％，15％的双氧水分解反应失控特性，建立了反应失控的临界判据。结果表明：温和反应阶段，系统温度和压力缓和升高，温升速率保持恒定；失控反应阶段，系统温度和压力急剧上升，温升速率出现明显的峰值；质量分数10％双氧水最高失控温度为90．0℃，最大压力为3．07 MPa，最大温升速率为10．7℃/min。质量分数增大，则失控剧烈程度增大。提出采用温度趋势判据和温升速率均值判据作为反应失控的判定准则。对比质量分数10％，15％双氧水分解反应在不同判据下的失控临界点发现，2种判定准则均能实现失控辨别，但精度取决于阈值设定。单一准则下，小的阈值灵敏，但误报率高。

The thermal decomposition of hydrogen peroxide is apt to cause runaway reaction with explosive hazard. Using vent test simulation device of bench scale,the characteristics of hydrogen peroxide decomposition with mass fractions of 1 0% and 1 5% were studied.The critical criterion for runaway reaction was established.The results show that temperature and pressure rise mildly in mild reaction stage with a constant temperature rise rate;in runaway reaction stage,temperature and pressure rapidly increase with an obvious peak value of temperature rise rate.The maximum temperature,maximum pressure and maximum temperature rise rate of hydrogen peroxide runaway reaction at 1 0% mass fraction are 90.0 ℃,3.07 MPa and 1 0.7 ℃/min respectively.The runaway reaction intensity increases with the mass fraction increasing.Two reaction runaway criterions of temperature trend criterion and the average temperature rise rate criterion were proposed according to the runaway characteristic.The comparison of 1 0% and 1 5% mass fractions hydrogen peroxide decomposition reaction under different runaway criteria critical points shows that both can identify a runaway reaction in advance,but their accuracy depends on the threshold setting.By one criterion,the smaller threshold is sensitive,but the rate of false alarm is high.
