The impact of four inorganic acids (hydrochloric, sulfuric, nitric and perchloric) and six organic acids (formic, acetic, citric, tartaric, oxalic and ascorbic) on the acid concentration in raw TATP crystals and the behavior of TATP during heating have been studied. The residual acid content in solid TATP depends on the type of acid and on its concentration in the reaction mixture. Increasing the concentration of acid in the reaction mixture leads to a higher acid content in TATP crystals. Sublimation of TATP during storage also has a significant impact on the acid concentration in TATP crystals. Sublimation of TATP gradually increases the content of non‐volatile acid in TATP crystals (sulfuric and solid organic acids) while the content of volatile acids (hydrochloric, nitric) does not significantly change during TATP sublimation. The increasing sulfuric acid content in TATP crystals during sublimation decreases thermal stability of TATP and the start of TATP decomposition was observed even at 45 °C. The concentration of volatile hydrochloric and nitric acids does not change significantly in TATP crystals during sublimation and, therefore, the sublimation process does not have an impact on TATP's thermal stability in these cases.

TATP研究:TATP升华对TATP晶体中残留酸含量及其特性的影响

研究了四种无机酸(盐酸,硫酸,硝酸和高氯酸)和六种有机酸(甲酸,乙酸,柠檬酸,酒石酸,草酸和抗坏血酸)对原始TATP晶体中酸浓度和加热过程中TATP行为的影响。 。固体TATP中残留的酸含量取决于酸的类型及其在反应混合物中的浓度。增加反应混合物中酸的浓度会导致TATP晶体中的酸含量更高。储存过程中TATP的升华也对TATP晶体中的酸浓度有重大影响。TATP的升华逐渐增加了TATP晶体中非挥发性酸(硫酸和固体有机酸)的含量,而TATP升华过程中挥发性酸(盐酸,硝酸)的含量没有明显变化。升华过程中TATP晶体中硫酸含量的增加降低了TATP的热稳定性,甚至在45°C时也观察到了TATP分解的开始。升华过程中TATP晶体中挥发性盐酸和硝酸的浓度没有显着变化,因此,在这些情况下,升华过程不会对TATP的热稳定性产生影响。
