In the spirit of contributing to Peter Murray-Rust's initiative to collect Green Chemistry information, Andrew Lang and I have added a green solvent metric for 28 of the 72 solvents we include in our Solvent Selector service. The scale represents the combined contributions for Safety, Health and Environment (SHE) as calculated by ETH Zurich.
For example consider the following Ugi reaction solvent selection. Using the default thresholds, 6 solvents are proposed and 5 have SHE values. Assuming there are no additional selection factors, a chemist might start with ethyl acetate with a SHE value of 2.9 rather than acetonitrile with a value of 4.6.
Individual values of Safety, Health and Environment for each solvent are available from the ETH tool. We are just including the sum of the three out of convenience.
