### Abstract:

The value of the critical temperature (Tc), below which the thermal explosion of a chemical cannot occur, is indispensable to prevent such a chemical from exploding. In order to determine the Tc it has so far been necessary to measure the value in explosion experiments. Because of the inherent hazards, only few Tc values are available at present. Critical Temperatures for the Thermal Explosion of Chemicals introduces new and simple procedures to calculate the Tc. As a result Tc can be calculated for a range of chemicals, man.
