Synthesis and characterization of hexaalkylguanidinium TADC energetic ionic liquids

Four kinds of hexaalkylguanidinium 4,5-dicyano-1,2,3-triazole([C _n-guan][TADC], n=3,4,5,6) energetic ionic liquids were synthesized by an ion exchange technique.Their structures were identified by IR and ¹HNMR.Their density, solubility, thermal properties were studied.Their structures were identifed by IR, 'HNMR, solubility were tested in common organic solvents, density were measured by surface interfacial tersion meter, thermal properties were studied through TG, DSC method.The results showed that hexaalkylguanidinium TADC ionic liquids had good solubility in most of organic solvents. The maximum decomposition temperature was about 370°C, revealing that [C _3-6-guan][TADC] had good thermal stability.In the second heating process of DSC, ([C _n-guan][TADC], n=3,4,5) experienced four kinds of phases, glassy, supercooled state, crystalline solid and liquid.
