Sažetak
Mechanochemistry has the promising perspective to transcend traditional solution synthesis by supporting the concepts of green chemistry. However, a deeper understanding of the fundamental principles of mechanochemical processes require also the knowledge about energy transfer during milling, which is essential for optimisation of mechanochemistry in the industrial context and transferability of mechanochemical processing accross different milling technologies.1 Here, by using in situ Raman spectroscopy, we report a systematic investigation how milling parameters, milling frequency as well as size and mass of a milling ball, influence the kinetics of a purely mechanochemical oligomerization of nickel(II) dibenzoylmethanate. A detailed kinetic analysis accompanied by advanced numerical simulations revealed a linear correlation between the kinetic rate constant and the impact energy needed for the chemical transformation.
