In situ monitoring as tools to study mechanochemical reactions
We will here describe the development of mechanistic understanding from the first in situ monitoring by synchrotron powder X-ray difraction [1, 2], followed by laboratory Raman in situ monitoring [3, 4] and finally focus on the most recent quantitative evaluation from tandem in situ monitoring combining the two techniques in a high-throughput approach enabling quantitative assessment and kinetic analysis even in systems involving novel and short-lived phases of unknown crystal structures. These recent results provide the necessary infrastructure for a thorough mechanistic description of mechanochemical milling reactions which was thus far hindered mainly by the inability of their quantitative evaluation. We will address also the issue of the temperature of the reaction mixture and its influence of reaction kinetics and mechanisms. Quantitative assessment from tandem in situ monitoring, performed in seconds-time resolution, establishes also Raman monitoring as a quantitative in situ technique that is readily implemented in a conventional laboratory.
