Abstract

Four compounds

CL-14

NNHT

ANPZ-i and DNMT were investigated with density functional theory.Their optimized geometries and electronic structures were calculated at the B3LYP/6-311+G** level.Optimized geometries of these compounds showed that there were no imaginary frequencies

so they were stable on the potential energy surface.The heat capacities and enthalpies of some representative compounds at different temperatures form 100 K to 1 200 K were obtained by statistic thermodynamics.In order to calculate standard enthalpies of formation

isodesmic reactions were designed.The average molar volume and theoretical density were estimated by using the Monte-Carlo method.Furthermore

the detonation velocity and pressure of the derivatives were estimated by the Kamlet-Jacbos equation.The results showed that t

he ring of benzofuroxan

triazine

pyrazine and triazole are of aromaticity and the detonation velocities of these compounds were between 7.83

.44 km·s-1.Detonation performance suggests that these title compounds are good candidates for energetic materials.
