Ozonolysis is widely used in natural product and drug synthesis, however, the intrinsic exothermicity of the reaction and its quench combined with the potential accumulation of hazardous intermediates such as ozonide hindered the use of ozonolysis at a large scale. In the current investigation, we use calorimetry, DFT and in-situ IR to study styrene ozonolysis in batch mode at 223.15 K. The results (heat of reaction, concentration profiles) acquired from the batch reaction was used to develop a lab scale continuous stirred tank reactor. The continuous system outperformed batch ozonolysis in terms of superior temperature control and minimizing buildup of unstable intermediates.
