Solvent Selection Guides

A number of solvent selection guides have been published with the purpose of promoting the uptake of more sustainable solvents.  These guides give the user a quick method of identifying problematic solvents and subsequently recommending preferred alternatives. Whilst it is important to have a sound understanding of issues and the wider implications surrounding the solvents you use in your research, it is not necessarily practical to spend significant amounts of time analysing each individual substance.  One of the advantages of using selection guides is that the data collection and analysis has already been performed. The individual ranking or grouping within the guides allows you to make an informed decision as to the most appropriate choice for your needs.  Efforts have been made recently to consolidate and combine solvent guidance.  A list of guides and other recommended reading can be found here.
