In the pursuit of advancing imidazolium-based energetic ionic liquids(EILs),the current study is devoted to the synthesis and characterization of 1,3-dibutyl-imidazolium azide([BBIm][N3]),as a novel member in this ionic liquids class.The chemical structure of this EIL was rigorously characterized and confirmed using FTIR spectroscopy,1D,and 2D-NMR analyses.The thermal behavior assessment was conducted through DSC and TGA experiments.DSC analysis revealed an endothermic glass transition at Tg=-61 ℃,followed by an exothermic degradation event at Tonset=311 ℃.Similarly,TGA thermograms exhibited a one-stage decomposition process resulting in 100％mass loss of the sample.Furthermore,the short-term thermal stability of the azide EIL was investigated by combining the non-isothermal TGA data with the TAS,it-KAS,and VYA/CE isoconversional kinetic approaches.Consequently,the Arrhenius parameters(Ea=154 kJ·mol-1,Log(A/s-1))=11.8)and the most probable reaction model g(a)were determined.The observed high decomposition temperatures and the significantly elevated activation energy affirm the enhanced thermal stability of the modified EIL.These findings revealed that[BBIm][N3]EIL can be a promising candidate for advanced energetic material application.
