摘要: In recent years, novel hypergolic ionic liquids (HILs) have attracted much attention in energy and fuel fields due to their prominent advantages, including low volatility, high thermal stability, excellent energetic performances, outstanding designability. To investigate the influence of cation structure on properties performances HILs, nine different imidazolium dicyanamide-based were prepared, characterized, evaluated as potential fuels. The heat formation net proton transfer (NPT) energies calculated by an optimized theoretical model. Ignition delay (ID) time was obtained a droplet test with high-speed camera. results suggest that all possess density (>1 g/mL) stability. 1-Ethyl-3-methyl dicyanamide has lowest viscosity 15.2 cP, 1-allyl-3-methyl shortest ID 25 ms. viscosities, densities, depend ...
