Synthesis, Characterization and Properties of 1,6-Bis (3-methyl-1-yl) hexane Dicyanamide

Some mono and di imidazolium-based ionic liquids with dicyanamide were synthesized and characterized. The synthesis of these compoundes were done based on alkylation reaction of N-methylimidazole followed by anion exchange. The structure of novel ionic liquids were identified by using FT-IR, 1HNMR spectroscopies and elemental analysis. Among the synthesized ionic liquids, thermal properties of 1,6- bis(3-methylimidazolium-1-yl)hexane dicyanamide [MIm2C6.DCA2] were studied with thermogravimetry (TG) and differential scanning calorimetry (DSC). Thermal decomposition of this ionic liquid was exothermic and it was thermally stable up to 311 °C. In additional, the ignition delay (ID) of selected ionic liquid was measured by high speed camera. The measured ID for this ionic liquid was 37 ms.
