Its structure was confirmed by 1H NMR, IR, and MS. The effects of various reaction parameters, including stoichiometry, reaction temperature and time, were investigated in details. In addition, the physical and chemical properties of this energetic surfactant were measured. 展开更多

The thermal decomposition kinetics of 1-amino-l,2,3-triazolium nitrate(ATZ-NO3) was investigated by non-isothermal TG-DTG at various heating rates(2,5,10,15 and 20 ℃/min).The results show that the thermal decomposition of ATZ-NO3 consists of two stages corresponding to the losing of nitrate anion,substituent group and the splitting of triazole ring respectively.The kinetic triplets of the two stages were described by a three-step method.First,the differential Kissinger and intergral Ozawa methods were used to calculate the apparent activation energies(E) and pre-exponential factors(A) of the two decomposition stages.Second,two calculation methods(intergral (S)atava-(S)esták and differential Achar methods) were used to obtain several probable decomposition mechanism functions.Third,three judgment methods(average,double-extrapolation and Popescu methods) were used to confirm the most probable decomposition mechanism functions.Both reaction models of the two stages were randominto-nucleation and random-growth mechanisms with n=3/2 for the first stage and n=1/3,m=3 for the second stage.The kinetic equations for the two decomposition stages of ATZ-NO3 may be expressed as da/dt=1013.60·e-128970/RT(1-α)[-1n(1-α)]-1/2 and da/dt=1011.41·e-117370/RT(1-α)[-1n(1-α)]-2/3.The thermodynamic parameters including Gibbs free energy of activation(△G≠),entropy of activation(△S≠) and enthalpy of activation(△H≠),for the thermal decomposition reaction were also derived. 展开更多
