Liquid‐Assisted Grinding Mechanochemistry in the Synthesis

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.

2020-6-19  Elucidation of the structure of novel compounds which are not compatible with NMR, is often facilitated by single crystal XRD (SCXRD). The data from SCXRD can be used to simulate powder patterns for comparison with the mechanochemically synthesized powders. Colour changes during grinding can also be indicative of reaction success.

Mechanochemistry an overview ScienceDirect Topics

Mechanochemistry, conducted by grinding or milling, is a powerful strategy for rapid, clean, and environmentally friendly synthesis of coordination compounds and polymers, which avoids bulk solvent and limitations of solution-based chemistry, such as solvolysis and solvent complexation.

Vortex grinding for mechanochemistry: application for

An automated grinding method based on a vortex mixer has been developed. The method enables simultaneous grinding and UV-irradiation, as well as in situ monitoring of solid-state reactivity.

Mechanochemistry: Toward green synthesis of metal–organic

2021-2-28  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 contrast, in mechanochemistry only a sufficiently efficient ball mill, the corresponding grinding bowls and balls as well as educts and if necessary suitable additions are needed. Differently as with the classic synthesis of solids, in this way many chemical reactions can be conducted in a non-thermal manner. Details are found here:

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).
