Synthesis and Analysis of Energy Characteristics of a Novel Energetic Ionic Salt Based on Dinitramide Anions
摘要
Abstract
To further explore the application potential of novel dinitramide energetic ionic salt(DBDN)with non-hygroscopic property,the synthetic route of DBDN was optimized.The standard molar enthalpy of formation(ΔfHθm)was calculated accord-ing to the measured constant volume heat of combustion(Qv).The energetic properties of DBDN in composite modified double base(CMDB)propellant and low signature propellant were calculated by RAMJ software.The kinetics of thermal decomposition of ammonium perchlorate(AP)catalyzed by DBDN were studied by Kissinger equation.Results indicate that the optimized syn-thetic conditions for DBDN are as follows:reaction temperature of 65℃,solvent of CH3CH2OH/H2O(volume ratio 10∶1),and reaction time of 5 hours.The Qv and ΔfHθm values of DBDN are-(13525.5±3.28)J·g-1 and-(17.36±0.24)kJ·mol-1,respec-tively.The calculation results show that the DBDN replaces 8%to 14%of AP,the performance of CMDB propellant is signifi-cantly improved.In the formulation of low signature propellant,DBDN has the ability to reduce the combustion chamber tem-perature(Tc)and the tail flame temperature(Te)by 17 times and 11 times larger than that of ADN respectively,and there is also no HCl gas in the combustion products.However meanwhile,DBDN weakens the energy performance of the propellants to some extent.In addition,the Kissinger equation shows that the addition of 10%mass fraction of DBDN decreases the activation energy of thermal decomposition of AP by 27.5 kJ mol-1,which is beneficial to catalyze the thermal decomposition of AP at high temperature,indicating that DBDN has the potential to adjust the burning rate and pressure exponent.关键词
