Solvents and sustainable chemistry

Solvents have many uses, both commercial and domestic. In the chemicals industry, solvents are used in the production of chemicals as media for chemical reactions and for chemicals separation/purification. Here, I attempt to demonstrate how appropriate selection of solvents for chemicals processing has been used to improve the sustainability of these processes using examples that have been, to the best of my knowledge using publicly available information, in commercial use at some time. These have been selected for illustrative purposes and are not an exhaustive collection of all the available examples in the literature.
