Alternative Solvents for Green Chemistry

---

Everyone is becoming more environmentally conscious and therefore, chemical
processes are being developed with their environmental burden in mind.
Of course, this also means that more traditional chemical methods are being
replaced with new innovations. This includes new solvents.

Solvents are everywhere, but should they be? They are used in most areas
including synthetic chemistry, analytical chemistry, pharmaceutical production
and processing, the food and flavour industry and the materials and coatings
sectors. But, the principles of green chemistry guide us to use less of them, or to
use safer, more environmentally friendly solvents if they are essential. Therefore,
we should always ask ourselves, do we really need a solvent? Chapter 2
explains some of the challenges and successes in the field of solvent-free
chemistry, and the answer becomes apparent: not always!

In the introductory chapter, some of the hazards of conventional solvents
(e.g. toxicity and flammability) and their significant contribution to waste
streams are highlighted. The general properties of solvents and why and where
they are used are outlined. Additionally, EHS (Environmental, Health and
Safety) assessments and life cycle analyses for traditional and alternative solvents
are described. It becomes clear that often a less hazardous VOC is
available and that although only ‘‘light green’’ (or at least ‘‘less black’’) in
colour, they can be used as an interim measure until a more satisfying option
becomes available. In each of the subsequent chapters, where possible, the use
of an alternative solvent is described for a range of chemical applications
including extractions, synthetic and materials chemistry. At the beginning of
each of these chapters, some of the advantages and disadvantages of that
medium are laid out.
