To understand better the thermal decomposition characteristics of organic peroxides, a C80 heat flux calorimeter was used
and the decomposition pattern of cumene hydroperoxide and di-tert-butylperoxide were classified as auto-catalytic and nth order reaction, respectively. Based on the scanning results with the C80 at several differing rates of heating, the thermal
decomposition behavior of organic peroxides under isothermal storage at lower temperature was simulated with a model-free
simulation. Simulated results showed that the calculated conversion of cumene hydroperoxide as a function of time was in good
agreement with experimental data obtained with the TAM-III high sensitivity thermal activity monitor.
The thermal decomposition characteristics of gold acetate to produce gold nanoparticles were investigated. A rapid and violent
fragmentation of the gold acetate particles was observed at approximately 103±20°C when a rapid heating rate of 25°C min−1 was used, leading to formation of nanosized spherical and partially coalesced gold particles. Particle size analysis was
used to investigate possible relationships between the gold acetate crystallite size and the gold nanoparticles produced by
thermal decomposition. The results indicate rapid (<0.14 ms) coalescence of the gold particles occurs for fragments in close
The effects of fullerenes, including fellerene soot (FS), extracted fullerene soot (EFS) and pure C60 on the thermal decomposition of ammonium perchlorate (AP) compared with traditional carbon black (CB) catalyst has been studied
by employing thermogravimetry (TG), differential thermal analysis (DTA), infrared spectroscopy (IR) and ignition temperature
experiments. The results showed that the addition of CB and FS to AP reduced the activation energy as well as the temperature
at maximum decomposition rate, but that of EFS and pure C60 had little effect on the thermal decomposition of AP, and among all catalysts, FS was the best one.
thermally activated solid-state reactions to obtain thermal stability parameters of solids [ 4 – 8 ]. The kinetics of the thermaldecomposition of inorganic materials could be markedly affected by pre-treatments, by the shortening of the induction period
The thermal decompositions of anhydrous fluorosilicates M2SiF6 (M=Li, Na, K, Rb, Cs) and MSiF6 (M=Ca, Sr, Ba) were investigated. The decompositions proceeded according to a simple acid-base mechanism with evolution of SiF4. The influence of the cationic counter-ion acidity (expressed by means of the electronegativity force) on the course of thermal
decomposition was estimated quantitatively.
A series of six nitrates(V) hydrates of 4d-metals as well as mercury and cadmium thermal decomposition was examined by DTA,
TG and EGA techniques. It was found that thermal decomposition of d-metals nitrate(V) hydrates proceeds in three stages: partial
dehydration, oxo-nitrates and hydroxide nitrates formation and metal oxides formation. General chemical equations for all
decomposition stages were proposed. It was found that dehydration of hydrated salts is accompanied by partial decomposition
of nitrate(V) groups.
The thermaldecomposition of polyacrylamide (PAA) has received continued attention in the literature [ 1 – 5 ] for the following reasons: (i) PAA is used as an important thermoplastic material in many industries
The thermal decomposition of antituberculous, local anaesthetic and calcium salts of organic acids used as the drugs has been
studied by differential thermal and thermogravimetric techniques. General characteristics of their thermal decomposition has
been made. The effect of sample size over the range 20–200 mg and heating rate over the range 3–15 deg·min−1 on the thermal degradation has been investigated. The values of the kinetic parameters has been also determined.
Combined TG/DTA techniques have been used to study the thermal decomposition of R3PAuCN (where Ris ethyl, cyclohexyl, o-tolyl, m-tolyl, p-tolyl, allyl, cyanoethyl,1-naphthyl and phenyl) complexes. It was observed that all of these complexes underwant decomposition
cum redox reactions in the range of 200–600oC with evolution of both transligands, which are phosphine and cyanide, leaving
metallic gold as a residue. The thermal decomposition of o-Tol3PAuCN has revealed that this is a stepwise process. In the first step decomposition takes place with evolution of phosphine
and generation of AuCN, which in second step undergoes a redox reaction to produce metallic gold. The DTA curves have also
confirmed these results.
Thermaldecomposition of solids is an important field of solid state chemistry with wide technical applications and has been used to obtain thermal stability parameters of solids [ 1 – 4 ]. The thermal
