N1,N1,N2,N2-tetramethylethane-1,2-diamine based ionic salts(TMEDA), N1,N1,N1,N2,N2, N2-hexamethylethane-1,2-diaminium dicyanamide(HMEDA-(DCA)2) was prepared following the well-known chemical reaction scheme. The chemical structure of the HMEDA-(DCA)2 was confirmed using 13C NMR spectrum and elemental analysis. The ignition delay of 40 wt% HMEDA-(DCA)2 solution was controlled to 20-100 msec dramatically using alkali metal salts, Li(CH3COO), Mg(CH3COO) and Ca(CH3COO) as a co-catalyst when white fume nitric acid was utilized as an oxidizer and also the oxidizer of low toxicity such as hydrogen peroxide was utilized. |
