有机化合物爆炸下限的预测

Prediction of the lower explosive limits of organic compounds

根据化学热力学原理和爆轰原理 ,探讨了有机化合物的爆炸下限与燃烧热之间的定量关系 ,提出一种预测有机物爆炸下限的方法 ,计算结果表明 ,预测值和实验值非常吻合 ,平均误差0 .18% ,该方法不仅能够预测有机化合物的爆炸下限 。

Based on the principle of detonation and chemical thermo-dynamics,the lower explosive limits(LEL) of organic compounds were studied,and developed a method to predict the lower explosive limits of organic compounds using the data of combustion heat.The calculated results showed that the predicted LEL agreed with the experiment data satisfactorily,and the mean deviation was 0.18% for 67 organic compounds.Not only can the method be used to predict the LEL of organic compounds,but only help to understand the quantitative relation between LEL and the heat of combustion.
