硝酸铵溶液的氯催化分解

Decomposition of Ammonium Nitrate Catalyzed by Chlorine Ion in Acidic Solution

为了探讨氯化物对硝酸铵水溶液热分解特性的影响,用量气法进行了一系列试验。结果表明:在含有氯化物的酸性硝酸铵(AN)溶液中,AN的分解速率与硝酸浓度的平方成正比,分解速率的倒数与氯离子浓度的倒数呈线性关系,水强烈阻碍该反应。讨论了该反应的反应机理。

To investigate the influence of chloride on thermal decomposition of ammonium nitrate solution, a series of tests were done with gas volume method. Results show that the decomposition rate of ammonium nitrate is proportional to square of concentration of nitric, reciprocal of the rate of decomposition is linear with reciprocal of concentration of chlorine ion. Water hampers the decomposition rate greatly in acidic ammonium nitrate solution containing chloride. The reaction mechanism is discussed.
