摘　　要：采用连续喷雾干燥的方法,制备亚微米级的球形间苯三酚铁催化剂。用热重-差示扫描量热分析、扫描电镜和傅里叶转换红外线光谱仪对间苯三酚铁催化剂的形貌、粒度和组分进行表征。运用差示扫描量热测试方法,研究间苯三酚铁对六硝基六氮杂异伍兹烷（CL-20）的热分解过程及动力学参数的影响。研究结果表明：间苯三酚铁样品均呈球状颗粒,且流散性非常好,粒度大多分布在500~1 000 nm之间;能明显地促进CL-20的热分解性能,使得CL-20的第一分解峰温最大可提前15.1℃;CL-20/间苯三酚铁的活化能较单一的CL-20提高了81.4 k J/mol.Sub-micron spherical phloroglucinol-Fe is prepared by spray drying. The morphology,particle size and composition of products are characterized by using TG-DSC,SEM and FTIR. The effect of phloroglucinol-Fe on thermal decomposition and kinetic parameter of hexanitroheraazaisowurtyzitane（ CL-20）is studied by means of DSC. The research results show that the products are spherical and diffusive. Particle size is in the range from 500 nm to 1 000 nm. The product can obviously promote the decomposition performance of CL-20 so that the first decomposition peak temperature is shifted 15. 1 ℃ ahead. The activation energy of CL-20 / phloroglucinol-Fe is increased by 81. 4 k J / mol compared with CL-20.
