Abstract
To find suitable components for energetic eutectic mixtures,3-amino-2,4,6-trinitroanisole with an overall yield of 76% was synthesized via the sequence methylation-VNS amination of commercial picric acid.And its properties were preliminarily studied by IR,1H NMR and elemental analysis.The mechanism of methylation and VNS amination were discussed.DSC-TG curves show that the endothermic peak temperature is 133.77 ℃ and the exothermic peak temperature is 254.10 ℃.The massloss is about 1.71% at 199.6 ℃.H50 is 82.5 cm and the friction sensitivity is 0%.V50 is 11.42 kV and E50 is 1.99 J.The theoretical detonation velocity is 7.459 km·s-1(ρ=1.709 g·cm-3),and the theoretical detonation pressure is 22.9 GPa(ρ=1.709 g·cm-3).Results show that 3-amino-2,4,6-trinitroanisole is stable to heat.The theoretical detonation velocity and pressure of 3-amino-2,4,6-trinitroanisole are larger than that of TNT.
