Prediction and evaluation of the reactivity of self-reactive substances using microcalorimetries

Kinetics of acid-catalyzed cleavage of cumene hydroperoxide

“…These kinetics do not account for the endothermic dehydration of DMBA to ␣-methyl styrene nor do they address the more recent possibility that thermal decomposition is autocatalytic [15,16]. The firstorder reaction and activation energies are consistent with earlier investigations [8,9], though higher than the 1/2-order seen in other recent papers [17,18].…”

Thermal characteristics of aluminum nanoparticles and oilcloths

“…In the present DSC thermograms, the rate of heat flow increased rapidly to a maximum and then decreased rapidly. This feature corresponded to an nth order reaction [22]. Based on the rate equations described above, the reaction rate was almost proportional to the square of ANP concentration, which was consistent with the n values shown in Table 1.…”

“…For spontaneous combustion, thermal behavior can be analyzed by isothermal and temperature-programmed heating [20]. Differential scanning calorimeter, DSC, has been invoked to predict the coal combustibility [21] and the reactivity of self-reactive substances [22]. Also, self-accelerating decomposition temperature, SADT, of self-reactive substances has been evaluated by Calvet 80 calorimeter, C80 [23].…”

Effects of acetone on methyl ethyl ketone peroxide runaway reaction

“…Stoessel applies DSC to evaluate the thermal stability of nitro-aromatics, and then obtains the safety parameter of time to maximum rate (TMR) [5]. Miyake et al use microcalorimetries for evaluating the thermal hazard of self-reactive substances of CHP in chemical processes [6]. The accelerating rate calorimeter (ARC) also has been applied to calculate the safety parameters reported by Whitmore and Wilberforce [7].…”
