Abstract Experimentally determined partition coefficients for DMMP between NaCl-saturated water and 20 solvents were correlated using the solvatochromic parameters α, β, and π*. An inverted LSER was then used to predict α for 7 additional solvents. The new cohesion parameters αβ and π*2 were found to be more representative of cavity formation than δ H 2 . Most importantly, it was essential to include either αβ or δ H 2 in the LSER. The partition method appears to be a useful adjunct to solvatochromic techniques in refining and extending the α scale of solvent acidity and could be used to rationalize solvent selection in extraction processes.
