Solvation Parameters. Part 4: What is the Impact of Recent Chromatographic Data Update?

ABSTRACT

Accurate solvation parameters have been established using solely gas/liquid partition data by gas/chromatography from the Kováts group (Laffort et al. J. Chromatog. A, 2005, 1100, 90-107). Because these chromatographic data have been recently updated (Kováts and Kresz, J. Chromatog. A, 2006, 1113, 206-219), the solvation parameters of the involved solutes and stationary phases have been entirely computed on again. It appears from this enquiry that the solute paramers values (127 compounds) are almost identical, whereas solvent parameters (11 stationary phases) have been slightly improved. A simple method of stationary phases classification is derived from these results, as well as a method for further determination of solute parameters.
