Thermal stability assessment

The evaluation process is completed with a thermal stability assessment of the products within the process temperature and time ranges. This assessment includes possible interactions of the products with the materials of construction of the equipment used. The methodology is the same as the one previously described for the reactants. It needs to be emphasized that depending on the circumstances the investigation cannot be limited to the pure products. Sometimes representative samples of reaction mixtures at different conversion stages need to be assessed as well.

The shift in temperature, at which the maximum power signal is recorded, however, is primarily due to kinetic effects and is observed in both devices. This effect actually is evaluated for the thermal stability assessment of substances or mixtures.
