Sažetak
Mechanochemistry and thermal energy are inherently related and hard to separate. During milling, mechanical energy is partially absorbed by the milled material and milling reactor, and the rest gets released as heat. It is often postulated that mechanochemical reactivity results primarily from these secondary thermochemical effects. We will present the new advances in mechanochemical reactivity accomplished by equipping mechanochemical processors with thermal controllers, for conducting the milling reactions at sub-ambient or elevated temperatures.1, 2 While the experimental setups are simple and easy to establish in laboratories, this external control of the bulk reaction mixture proved to have many benefits when compared to conventional mechanical processing. It leads to a dramatic increase in reaction rate and yield, the overall reduction in spent energy, but also to complete change of the reaction mechanisms, controllable synthesis of various products from the same reaction mixtures, and increased reaction selectivity. Due to its simplicity and advantages, the combination of temperature control and milling may soon become unavoidable for every synthetic laboratory.
