以3,5-二硝基水杨酸、硝酸氧锆和氢氧化钠为原料,合成出了3,5-二硝基水杨酸锆(DNS-Zr),采用有机元素分析、X 射线荧光光谱和傅里叶红外光谱(FTIR)对其进行了表征。在程序升温条件下,利用 TG-DTG 和 DSC 以及固相原位反应池/傅里叶变换红外光谱(RS-FTIR)联用技术,研究了3,5-二硝基水杨酸锆的热行为和热分解机理,认为3,5-二硝基水杨酸锆先失去一个结晶水,再分解为 ZrOCO3和大量的 C,同时大量放热,其最终分解产物为 ZrO2和 C。利用螺压工艺制备了含3,5-二硝基水杨酸锆的推进剂样品,研究了3,5-二硝基水杨酸锆对双基系推进剂燃烧性能的影响。结果表明,3,5-二硝基水杨酸锆对双基系推进剂的催化效率为10%~20%。

Zirconium 3,5-dinitrosalicylate(DNS-Zr)was synthesized firstly by using 3,5-dinitrosalicylic acid,zirconyl nitrate and sodium hydroxide as raw materials. Its structure was characterized by elementary analysis,X-ray fluorescence diffraction and FTIR spectra. The thermal behavior and decomposition mechanism of DNS-Zr in a temperature-programmed mode were investigated by means of TG-DTG,DSC and condensed phase thermolysis /FTIR techniques. The decomposition products of DNS-Zr are ZrO 2 and C. The sample of propellants containing DNS-Zr were prepared by extrusion technology,and the effects of DNS-Zr on combustion properties of DB /CMDB propellants were investigated. Results show that the catalytic efficiency of DNS-Zr is 10% -20% .
