TMNTA was synthesized using tris( hydroxymethyl) nitromethane as raw material,via the two?step reactions of esterif?ication, azidonation with a total yield of 83.0%.Its structures were confirmed by IR,NMR and elemental analysis.The affecting fac?tors of azidonation were studied.The optimum conditions of the reactions were:nexp:ntheory=1.10 for NaN3(molar ratio),10%~25% of the total volume of acetone?H2 O and reaction time 1 h. Some physicochemical properties of TMNTA were obtained by the tests.Results show that the density is 1.45 g/cm3,decomposition temperature is 235.7℃,glass transition temperature is-26.23 ℃, H50=44.7cm(2 kg),friction sensitivity is 4%(66°).
