DTBP, such as temperature and pressure traces versus time. The heat-wait-search (H-W-S) method for detecting the self-heating rate was employed. If the self-heating rate was greater than 0.1 °C min −1 , the H-W-S and main heater would be immediately

and at the same time to decrease the self-heating an approach based on significant ballasting (“dilution”) of the reactant was proposed. Two methods of dilution were developed: “mechanical” and “thermal”. The basic experimental scheme and cells used in

]. Under the experimental conditions, if the self-heating rate exceeds 0.2 °C min −1 , and the heat-wait-search mode is terminated and the instrument enters adiabatic (AK) mode. In AK mode, the main heater directly to the test cell is switched off

, over a long time, an abrupt self-heating of the resultant liquid started. In essence, exothermic decomposition reactions can begin when the solid and liquid phases coexist on one container [ 12 ]. Another parameter for determining thermal

achieve this, a low rate of heating has been used in the final stages. The chosen target rate has extended the oxidation reaction over a period of more than 2 h effectively eliminating self-heating problems. Thus, the technique offers the possibility of

followed by a seek or search period. Again during this period (typically 20 min) no heat was provided by the radiant heater, and any temperature drift, upwards or downwards, is observed. If there was upward temperature drift, it was caused by a self-heating
