The AHP tool provides the chemist with a tool that can be
applied during the early stages of development for the selection
of solvents. The tool aids to obtain a ranked list of solvents
to try in experimental trials. It also aids the chemist to replace
or look for solvent alternatives. The case presented in this
paper was run with a database of 60 solvents. Of course more
extensive databases would increase the capabilities of the
analysis. The tool also helps the user to customise the solvent
characteristics and replace characteristics that might bring
future issues. This could be the case when solvents do not
present good HSE characteristics. Generally, all solvents will
present some benefits and some disadvantages. Therefore, it
is the scope of this tool to develop alternatives for exploring
a wide pool of choices in the early stages of development.
This should lead to a more sustainable process development
regarding solvent selection.
