Abstract

Five malonanilide derivatives (M1-M5) were prepared by the reaction of ethyl malonate with aniline derivatives. These compounds were investigated as new stabilizers for double-base propellants (DBPs). The evaluation process has been performed through thermal stability tests, thermal analyses measurements (TGA and DSC) and kinetic parameters calculations (E(a)). The results of the new stabilizers were compared with the results of the classical stabilizer N, N-diethyldiphenyl urea. It has been found that o- and p-dinitromalonanilides, in particular, showed better stability effect for DBPs than the classical one.

摘要

通过丙二酸二乙酯与苯胺衍生物反应制备了五种丙二酰苯胺衍生物（M1 - M5）。这些化合物作为双基推进剂（DBP）的新型稳定剂进行了研究。评估过程通过热稳定性测试、热分析测量（TGA和DSC）以及动力学参数计算（E(a)）来进行。将新型稳定剂的结果与经典稳定剂N，N - 二乙基二苯基脲的结果进行了比较。结果发现，特别是邻二硝基丙二酰苯胺和对二硝基丙二酰苯胺对双基推进剂显示出比经典稳定剂更好的稳定效果。
