| 中文摘要 | Development of new hypergolic ionic liquids is the key in replacing toxic N,N-dimethylhydrazine as green liquids propellants. Three salts based on the new propan-2-ylidene methanetriamium cations and dicyanamide anion were synthesized and characterized by H-1 and C-13 NMR, IR and Raman spectroscopy, elemental analysis, and TG/DTA. In addition, their crystal structures were determined by X-ray single crystal diffraction. N-(propan-2-ylidene) methanetriamium dicyanamide (1) crystallizes in the monoclinic space group P2(1)/n, N,N'-bi(propan-2-ylidene) methanetriamium dicyanamide (2) in triclinic P - 1, and N,N',N"-tri(propan-2-ylidene) methanetriamium dicyanamide (3) in monoclinic C2/c. With heats of formation (from 1.56 to 1.80 kJ g(-1)) and densities (from 1.19 to 1.31 gcm(-3)) in hand, the detonation pressure (P) and velocity (D), and specific impulse (hp) values of salts were calculated as 8.94 GPa, 4989 m s(-1) and 174.3 s (1), 7.91 GPa, 4815 m s(-1) and 179.0 s (2), and 7.33 GPa, 4693 m s(-1) and 180.6 s (3), respectively. Impact sensitivities of 1, 2 and 3 were measured to be no less than 40 J by hammer tests, which places these salts in the insensitive class. Moreover, the resulting salts are hypergolic with white fuming nitric acid and exhibit potential as bipropellants. (C) 2014 Elsevier B.V. All rights reserved. |
