Microwaves: A Potential Technology for Green Process
Microwaves fi rst appeared in the chemistry and process research fi elds almost thirty years ago, saw a boom in interest, and then were more or less forgotten until now, with a renewed enthusiasm for them among the scientifi c community. Environmental constraints, standards limiting or even prohibiting the use of certain solvents, safetyrelated constraints-all these relatively recent measures have implications for processes. The use of microwaves as a means of heating may enable more sustainable synthesis or extraction processes meeting these demands to be proposed. In this chapter, we will cover microwave-based processes from this perspective by showing their advantages, their limits and their potential for integration in the industry.
