【摘要】 研究了用量热仪推算自加速分解温度(SADT)以评价有机过氧化物的热自燃危险性的方法。用C80II型微量量热仪所测得的物质的热流速曲线来求解有机过氧化物的化学反应动力学参数,根据Semenov热爆炸模型求得SADT。将一些有机过氧化物自加速分解温度的推算结果与实测值进行了比较。实验表明,由此推算得到的一些有机过氧化物的SADT与美国式测定方法十分接近。更多还原

【Abstract】 A method for the evaluation of the autoignition hazard from organic peroxides is proposed based on the calculation of the self accelerating decomposition temperature(SADT) via the experiment by means of a C80Ⅱ microcalorimeter. The chemical kinetic parameters of some organic peroxides were calculated using heat flux data measured by virtue of the C80 microcalorimeter, and their SADTs were obtained based on the Semenov model. The SADTs estimated from the C80 data are in good agreement with the US TEST results.更多还原
