It is known that solvents may affect the reaction mechanism or reaction rate. This is often the case for synthesis reactions, but may also occur for secondary reactions. Therefore, the nature of the solvent may affect the thermal stability of reaction masses. Thus, the effect of solvent on thermal stability should be checked in the early stages of process development. Here again, thermal analysis by DSC is a powerful technique, since it allows a rapid screening with some milligrams of reaction mass. An example is given in Figure 11.16. 

Accidents happening in polymerization reactors are practically always due to a lack of control of the course of reaction caused by a disturbance of the heat balance, which results in a temperature increase leading to loss of control of the reactor and a runaway reaction. In this section a systematic procedure based on a failure scenario with six key questions, allowing assessment of the criticality of a process, is presented. Since the heat balance is at the center of our concerns in matters of thermal control of reactors, the different terms of the heat balance will be examined. Finally, aspects of the dynamic stability of reactors and of the thermal stability of reaction masses are analyzed.
