The thermal behaviors of the complexes of Cu(DMTZB)4X2 (DMTZB=3,3'-dimethyl-1-(1H-1,2,4-triazol-1- yl)-2-butanone, X=NO3 or ClO4) and Cu(DMTZB)2 X2 (X = Br or Cl) in a nitrogen atmosphere were studied un-der the non-isothermal conditions by simultaneous TG-DTG-DSC, EDS and elemental analysis techniques. The re-sults showed that their decomposition proceeded in three different ways mainly depending on the anions in the molecules. The heat effect associated with the decomposition step of DMTZB molecules was also different. The decomposition mechanisms and the kinetic parameters of DMTZB were determined and calculated by jointly using four methods, which showed that its pyrolysis was controlled by D3 mechanism but with different activation ener-gies and pre-exponential factors for different complexes.

The thermal behavior and kinetic parameters of the major exothermic decomposition reaction of the title compound in a temperature-programmed mode were studied by means of TG-DTG and DSC. The critical temperature of thermal explosion was calculated. The effect of the title compound on the combustion characteristic of composition modifier double base propellant containing RDX was explored with a strand burner. The results show that the kinetic model function in differential forms, the apparent activation energy(E a) and the pre-exponential factor(A) of the major exothermic decomposition reaction are 3(1-α)[-ln(1-α)] 2/3, 190.56 kJ/mol and 10 13.39 s -1, respectively. The critical temperature of thermal explosion of the compound is 353.08 ℃. The kinetic equation of the major exothermic decomposition process of the title compound at 0.1 MPa could be expressed as dα/dT=10 14.65(1-α)[-ln(1-α)] 2/3 e -2.2920×104/T. As an auxiliary catalyzer, the title compound can help the main catalyzer of lead salt of 4-hydroxy-3,5-dinitropyridine to accelerate the burning rate and reduce the pressure exponent of RDX-CMDB propellant.

Rigid polyurethane foams were fabricated with five kinds of liquefied sugarcane bagasse polyols （LBP）. The foams derived from sugarcane bagasse were investigated by thermogravimetric analysis （TGA）, and the thermal degradation data were analyzed using the Coast-Redfern method and Ozawa method to obtain the reaction order and activation energy. The results indicate that the sugarcane bagasse-foams exhibit an excellent heat-resistant property, whereas their pyrolysis procedures are quite complicated. The reaction as first order only takes place from 250 to 400 ℃, and the pyrolysis activation energies vary from 20 to 140 kJ/mol during the whole pyrolysis process.

A typical nitroimine bistriazole（DNABT） was synthesized with high yield（90.4%） by nitration reaction from DABT in HNO3 and NH4NO3. Furthermore, a novel cocrystal（1） consisting of DNABT, H2O and DMSO in a 1：2：2 molar ratio was analysized on the crystal structure. Cocrystal 1 crystallizes in the triclinic system, space group P1 with a = 6.3124（18）, b = 8.233（2）, c = 9.775（3） A, β = 98.326（4）°, V = 481.59（74）A^3, Z = 2, Dc = 1.55 g/cm^3, F（000） = 234, μ = 0.337 mm^-1, S = 1.078, the final R = 0.0609 and w R = 0.2743. Additionally, the crystal structure is built up by four strong and seven weak hydrogen bonds. And the hydrogen bond network contributes to the stability of DNABT molecule. Typical TGA and DSC curves indicate the cocrystal 1 includes one endothermic and one exothermic decomposition processes, and the peak temperature at each process is 164.0 and 245.0 ℃. The nonisothermal decomposition kinetics analysis was performed by means of the Kissinger and Ozawa methods. The apparent activation energy（Ea） and pre-exponential factor（A） of the two decompositions are 96.0 kJ·mol^-1, 108.1 s^-1 and 215.8 kJ·mol^-1, 1018.9 s^-1, respectively.
