Abstract

An automatic pressure tracking adiabatic calorimeter (APTAC) has been developed to obtain the thermokinetic and vapor pressure data during runaway reactions. The heat onset temperature is important data for estimating the thermal hazardous materials. DTBP(di-tert-butyl peroxide)/toluene was chosen for evaluating the measurement values and the thermokinetic parameters. The relationships between the sample mass and the heat onset temperature in the addition to the maximum temperature were investigated to explain the heat of reaction measured by the APTAC. The apparatus properties and the reliability of the data obtained by the APTAC were examined on the basis of the experimental data.
