Liquid‐Assisted Grinding Mechanochemistry in the

Liquid‐assisted grinding (LAG) as an extension of traditional solvent‐free mechanochemical techniques by which a small amount of liquid is used as an additive to enhance and/or control reactivity, has been fruitfully applied in the screening of inclusion compounds, cocrystals, salts, solvates, and polymorphs.

Mechanochemistry: Toward green synthesis of

2021-6-1  A typical mechanochemical synthesis involves grinding/milling the mixture of solid precursors in a ball miller under solvent-free conditions (Neat Grinding, NG). Thus, it gives an opportunity to use insoluble metal sources, which sometimes are difficult to dissolve in the solvents used in conventional syntheses of MOFs.

In the course of grinding—especially in its fine phase connected with the complicated energy transformations—structural and chemical changes take place. In (c) in Chapter 1 (definition (c)) it was hinted that there is a limit of the fracturing effect and in Chapter 4 the phenomenon of agglomeration was dealt with in detail.

2020-6-19  Colour changes during grinding can also be indicative of reaction success. Therefore, mechanochemistry can allow for rapid screening of a huge number of different reactions in the search for interesting materials. However, don’t be too quick to dismiss an unsuccessful reaction if you haven’t tried liquid-assisted grinding (LAG).
