5. Controlling exothermic reactions

In fine and specialty chemistry, the vast majority of synthesis reactions are exothermic. As a result, it's essential to be able to control heat production, and hence the progress of the reaction. For this reason, in this section we focus on the study of reactions in the sense of characterizing them in terms of thermal risks, but we use this knowledge to design a safe reactor.

The study of the thermal safety of a synthesis reaction involves its control under nominal operating conditions, essentially the comparison of reaction power with cooling capacity, but also the study of its behavior in the event of malfunction.

After an introduction to experimental methods, we study two typical fine chemistry reactors, namely the batch reactor and the semi-batch reactor.
