Solvents are liquids that are capable of dissolving or dispersing other substances. They are used in very high volumes in industry and from a number of cradle-to-gate lifecycle studies, it is generally recognised that the major contributor to the lifecycle impacts of API synthesis is due to solvents. From a green chemistry point of view, solvents therefore become an area where greatest impact can be achieved by reducing the amount of solvent waste, and minimising human and environmental consequences through the choice and volumes of solvent used. 

Learning Objectives

By the end of this module you should:

  • Have a broad understanding of why we use solvents;
  • Be aware of issues surrounding the use of solvents;
  • Be able to identify solvents of concern.
