Terminology and Symbolism for Mechanochemistry
Classical solution chemistry seems not to fit properly in the new paradigm of green chemistry, which is crying out for a drastic reduction in the use of solvents, improved atom-economy, energy and cost efficiency. Mechanochemistry fits this role.
Mechanochemistry studies the effects of mechanical energy forces on physicochemical changes and transformations. Rapidly growing, it has applications in various areas of research, including organic synthesis, materials science, nanotechnology, catalysis, and green chemistry. In 2019, IUPAC acknowledged mechanochemistry as one of the top ten technologies for a more sustainable future, recognizing its potential as an environmentally friendly option for developing new processes and materials.
Nevertheless, the expansion of mechanochemistry and the wide range of materials, equipment, methods, and practices involved, have made obvious the lack of standardization and clarity in its terminology and symbolism. The ScienceDirect overview of the subject alone contains over twelve descriptions that provide definitions of mechanochemistry. Curiously, although the IUPAC Compendium of Chemical Terminology (the Gold Book) describes a mechanochemical reaction as one “induced by the direct absorption of mechanical energy,” it leaves undefined just what constitutes “mechanical energy,” and there is only one reference to mechanochemical processes, namely relating to polymers and functional polymeric materials. Detailed terminology pertaining to mechanochemistry and related disciplines is lacking.
With the support of IUPAC, this initiative will establish uniformity in the terminology and classifications employed in mechanochemistry. Additionally, standardized symbolism will be proposed to facilitate communication within the mechanochemical community. The project, which involves multiple stakeholders, will result in recommendations that will contribute to a more organized development of the subject and enhance its visibility and credibility as a distinct and important branch of chemistry.
