Thermal Decomposition of Nitropyrazoles

Physics Procedia, 2015
AbstractFully nitrated five-membered heterocycles (pyrazoles), polynitropyrazoles in particular, have been actively studied as promising high-energy materials. Polynitropyrazoles have high density and high enthalpy of formation combined with reduced sensitivity to external stimuli.

The products of the thermal decomposition of CH3CHO [PDF]

The Journal of Chemical Physics, 2011
We have used a heated 2 cm × 1 mm SiC microtubular (μtubular) reactor to decompose acetaldehyde: CH3CHO + Δ → products. Thermal decomposition is followed at pressures of 75–150 Torr and at temperatures up to 1675 K, conditions that correspond to residence times of roughly 50–100 μs in the μtubular reactor.

Behaviour of Thermal Degradation of Some Poly (4-amino-2,6-pyrimidinodithiocarbonate) Metal Complexes

Sultan Qaboos University Journal for Science, 2008
The thermal decomposition behaviour of the Fe(II), Co(II) and Ni(II) complexes of poly[4-amino-2,6-pyrimidinodithiocarbamate] has been investigated by thermogravimetric analysis (TGA) at a heating rate of 10°C min-1 under nitrogen.

Thermal decomposition of a fullerene mix [PDF]

Physical Review B, 1995
Experiments to characterize fullerene decomposition at temperatures above 973 K were conducted by spectroscopic analysis of samples heated in vacuo. The thermal decomposition can be described by first-order kinetics with an activation energy of 266±9 kJ/mol and a preexponential factor of 1.24×10^(9) s^-1.
