Use of solvents
Before looking at solvent replacement strategies, we first need to consider why we use solvents and what factors need to be taken into consideration when selecting a solvent. An insight on how we choose the right solvent for a reaction or purification can be found in Topic 2. It is also useful to consider trends in the use of different solvent types, as well as identifying the types of solvent that are being targeted for substitution through for example legislative or other measures. These points will be explored in more detail in this module.
