摘要
通过局部热感度试验和DSC-TG联用仪,研究了高氯酸铵(AP)和一种二茂铁衍生物(EMT)混合体系的热感度。结果表明,减小AP粒度或增加EMT含量,能缩小AP高低温分解峰之间的差距,提高AP低温分解量,混合物的局部热感度增加。AP存在下,EMT的侧链容易发生断裂,断裂后的二茂铁或二茂铁离子活性体对AP分解起催化作用。此外,EMT不利于AP的质子转移过程,但对HC lO4的分解有较强催化作用。
Thermal sensitivity of AP and ferrocene derivative（EMT） mixtures was studied by partial thermal sensitivity and DSC-TG coupling.The results indicate that reducing AP particle size or increasing the content of EMT can shorten the gap between high-temperature thermal decomposition peak of AP and low-temperature thermal decomposition peak of AP,enhance the low-temperature thermal decomposition amount of AP,and increase partial thermal sensitivity about mixtures of AP and EMT.In the presence of AP,side-chain of EMT is easily ruptured.Residual main skeleton,ferrocene or ferrocene ion,is the real catalyst to thermal decomposition of AP.Furthermore,EMT inhabits proton transfer process of AP,but it is a strong catalysis of EMT to decomposition of HClO4,one of initial decomposition product of AP.
