pH值对硝酸铵水溶液临界爆炸温度的影响

Influence of pH on the critical explosion temperature of ammonium nitrate solution

研究了氯离子含量一定时pH值对硝酸铵水溶液临界爆温的影响。结果表明,氯离子质量分数为1.0×10-4时,pH值越小,硝酸铵水溶液的临界爆温越低,且pH值与临界爆温值呈线性关系。本研究结果对硝酸铵的安全生产有重要的参考价值。

Maintaining the concentration of chlorine ion a certain value, the influence of pH on the critical explosion temperature of ammonium nitrate solution were studied in this article. The results show that, when the concentration of chlorine ion was 1 ×10^-4, the smaller of pH, the lower of the critical explosion temperature of ammonium nitrate solution, and the critical explosion temperature of ammonium nitrate solution was linear with pH. These results are of important reference to the hazard control in the process of AN production.
