Solvent Selection from the Green Perspective

In recent years, analytical chemists have increasingly adopted a sustainability viewpoint. Yet, at the same time, they still use traditional organic solvents for extractions and other procedures. In this installment of Sample Preparation Perspectives, we will look at solvent selection from green considerations. Trends on solvent use are presented, followed by a discussion on what makes a green solvent. Finally, the CHEM21 Solvent Selection Guide is examined as representative of tools for selecting green solvents for use in analytical methods and other chemical processes.
