1-氨基-3-硝基胍高氯酸盐的合成及性能表征
Synthesis and Performances Characterization of 1-Amino-3-nitroguanidinium Perchlorate
摘要
Abstract
To meet the demand for higher energy level in next generation solid propellants,1-amino-3-nitroguanidinium per-chlorate(ANGCl)was synthesized using guanidine nitrate as starting material.A systematic characterization of its key physico-chemical properties was conducted,including crystal structure,thermal behavior,detonation performance,enthalpy of forma-tion,oxygen balance,hygroscopicity,and compatibility with typical components of propellant.Furthermore,the energy char-acteristics of hydroxyl-terminated polybutadiene(HTPB)-based propellants employing ANGCl as the oxidizer were theoretically evaluated.The results indicate that ANGCl possesses a crystal density of 1.96g/cm3,a thermal decomposition peak tempera-ture of 141.9℃,a detonation velocity of 9113 m/s,and a detonation pressure of 36.83 GPa.Additionally,ANGCl has the characteristics of high enthalpy of formation(140 kJ/mol),favorable oxygen balance(18.23％),and suitable hydrogen con-tent(2.75％).Theoretical calculations show that HTPB-based propellant formulations containing ANGCl can achieve a maxi-mum specific impulse of 279.77s,with the average molar mass of combustion gases reduced to 24.91 g/mol.Compatibility tests reveal that the net gas evolution between ANGCl and aluminum powder(Al),AP,HTPB,or dioctyl sebacate(DOS)is less than 0.6mL,indicating good compatibility with these propellant ingredients.Under conditions of 25℃ and 65％relative humidity,the saturated moisture absorption rate of ANGCl is 2.09％,reflecting low hygroscopicity.These findings suggest that ANGCl is a promising high-energy oxidizer for HTPB-based solid propellants.关键词
