摘要： 为了研究过氧乙酸的爆炸危险性，采用绝热加速量热仪对13%过氧乙酸溶液进行了热危险性测试。通过数据校正和分析，得到了绝热条件下13%过氧乙酸溶液的初始放热温度为45.25℃，最大压力为1.31MPa，最高温升速率温度为113.10℃。结果表明，过氧乙酸溶液的热分解温度很低，在安全生产和储运过程中有一定的爆炸危险性。针对过氧乙酸的热危险性，提出采取适当措施，例如加强冷却，采用合理的泄放方式，以避免事故的发生。

Abstract:
13% Acetic hydroperoxide was investigated by accelerating rate calorimeter (ARC).From ARC test, the initial exothermic temperature was 45.25℃, the maximum pressure was 1.31 MPa, and the maximum self-heating rate temperature was 113.10℃.The measured results indicated that the acetic hydroperoxide was easy to decompose and had obvious explosive hazard.In the end, the paper discusses related prevention measures, such as cooling and reasonable relief method, to avoid hazard.
