SPP solubility parameters

Home :: Tables for Chemistry :: Eluotrope series

Details of the SPP solubility parameters (Solvent Polarity/Polarizability), together with a more comprehensive list and a discussion on solvent scales in general can be found at the →web site of Prof. Catalán (archived version).

The Solvent acidity (SA) parameter is correlated with →Dimroth-Reichardt E_T (→E_T vs SA), →Gutmann AN (→AN vs SA) and →Swain Acity (→Acity vs SA).

The Solvent basicity (SB) parameter is correlated with →Gutmann DN (→DN vs SB).
