What is the relationship between impacts and reaction progress in mechanochemistry?

January 05, 2023.

Well, it seems to be linear. That is, the reaction progresses linearly with the absorption of kinetic energy of the milling balls.

It is extremely difficult to study the effect of ball impacts independently of reactant mixing in a mechanochemical reaction. Unless one has the right reaction: here, the formation of the trimer of Ni(dbm)2 is exactly such a reaction. Following an in situ monitoring at different milling frequencies, using balls of different materials and sizes, using a sophisticated mechanochemistry-specific kinetic analysis, we come to a seemingly simple conclusion of a linear relationship between the absorbed energy and the reaction progress.
