乙酸对硝酸铵溶液热安定性影响的研究

摘要

利用C80微热量热仪，研究了不同含量乙酸对硝酸铵溶液热分解特性的影响。研究结果表明：乙酸对硝酸铵的晶变温度影响较小，但会使混合体系起始反应温度（Tonset）向前推移，表观活化能降低，从而对硝酸铵溶液热分解起到催化作用。%By testing the mixture of acetic acid and ammonium nitrate with C80, the effect of acetic acid on thermal decomposition of ammonium nitrate was investigated. It shows that the crystal temperature of ammonium nitrate changed a little with the addition of acetic acid, the initial reaction temperature was moved forward and apparent activation energy was lowered, when a small quantity of acetic acid is added into the mixture, so the acetic acid has certain catalytic action to thermal decomposition of ammonium nitrate.
