Preparation and Properties of Bitetrazolyethane Aminoguanidine
摘要
Abstract
A new kind of high-nitrogen compound bitetrazolyethane aminoguanidine monohydrate(CH7N4·C4H4N8·H2O)was prepared by an one-pot method.Its single crystal was characterized by FT-IR spectroscopy and elemental analysis and the crystal structure is measured by X-ray single crystal diffractometry. Its thermal properties were measured by TG-DTG and DSC. Its non-isothermal kinetic parameters were calculated by using Kissinger′s method and Ozawa′s method. Its heat of combustion was tested through an oxygen bomb calorimetry. Its detonation velocity (D) and detonation pressure (P) were computed by K-J formula and the mechanical sensitivity was tested. The results show that the crystal is monoclinic, its space group is C2/c (No.15) with cell parameters of a=1.1261(2)nm, b=0.71062(14)nm, c=2.7241(5)nm, β=95.95(3)°,V=2.1682(8) nm3, Z=4, and the theoretical density is 1.527g/cm3. It has good thermal stability with initial decomposition temperature of 289.3℃. Its non-isothermal kinetic parameters, apparent activation energy is 219.05kJ/mol, lg(A/s-1) is 38.61.The heat of combustion and enthalpy of formation are 9.515MJ/kg and 2892.2kJ/mol, respectively. The detonation velocity and detonation pressure are 6.95km/s and 19.3GPa. The impact sensitivity is higher than 50cm, and friction sensitivity is 0, revealing that the compound has low mechanical sensitivity and good thermal stability.关键词
