The foundation section on solvents introduces the idea that solvents are the area where greatest impact in terms of improving the greenness of a chemical process can be achieved.  It outlines that this can be achieved both by: 

  • Minimising human and environmental consequences through the choice and volumes of solvent used;
  • Reducing the amount of solvent waste.

In this topic we will explore these aspects in more detail.

By the end of this topic you should:

  • Understand why we use solvents;
  • Be aware of the factors that should be taken into consideration when selecting a reaction solvent;
  • Be aware of strategies for solvent reduction and replacement and their associated advantages and disadvantages.
