为研究有机磷酸稳定剂对双氧水的作用，利用绝热量热仪VSP2（vent sizing package 2）进行了不同浓度的氨基三亚甲基膦酸（ATMP）分别与纯双氧水以及含0.01%Fe3+的双氧水的放热测试，得到其在绝热条件下的热力学参数，并在此基础上计算出样品在起始温度为25℃时到达最大温升速率的时间 TMRad。结果表明：有机磷酸稳定剂能有效抑制温度、Fe3+对双氧水的催化分解作用，降低双氧水发生热失控的风险。双氧水的起始分解温度T0随着ATMP质量分数的增加而提高。在质量分数为0.04%ATMP的影响下，双氧水的起始分解温度T0可由50℃提高至115℃。

In order to evaluate the effect of polyphosphonic acid used as stabilizer on hydrogen peroxide decomposition,VSP2 (vent sizing package 2) was used to carry out thermal runaway reaction for various concentrations of amino trimethylene phosphonic acid (ATMP) with H2O2,and H2O2 mixed with 0.01%Fe3+. Thermodynamic parameters were recorded under adiabatic condition,and the time to reach maximum rate TMRad at 25℃ was obtained from the thermodynamics data. Polyphosphonic acid could restrain the effect of temperature and Fe3+on catalytic decomposition of hydrogen peroxide and reduce the risk of thermal runaway significantly. The exothermic onset temperature T0 of H2O2 increased with increasing concentration of ATMP. In 0.04%ATMP environment,T0 of H2O2 increased from 50℃ to 115℃.
