different solvents related to organic chemistry with grinding method

solvents Advancing Green Chemistry
Mechanochemistry does not use solvents at all but rather relies on a grinding mechanism to start and push a reaction. This field of chemistry has been applied to the production of pepto-bismol a compound that everyone is familiar with making the synthesis solvent-less. The students favorite part was the picture of the pepto-bismol ice-cream.

A review on the potential uses of deep eutectic solvents
Deep eutectic solvents are received as potential alternatives to the conventional organic solvents with other advantages such as renewability reusability biodegradability nontoxicity large-scale availability having very low vapour pressure and high thermal stability low flammability and easy in preparation (Bangde et al. 2016). Owing to these remarkable advantages DESs are now of growing interest in
