STATISTICAL-ANALYSIS OF SOLVENT SCALES - PART 2

The ''informative'' approach, an optimum design methodology, has been applied to two empirical models of solvents, that of Koppel and Palm a nd that of Kamlet, Abboud and Taft with the purpose to determine if th ey are identical, similar or very different. The experimental results necessary to establish the corresponding models are the keto/enol equi librium constants of 2,4-pentanedione carefully determined by H-1-NMR spectroscopy. The conclusion is that both models are only similar, bei ng one more precise (KP) and the other more robust (KAT).
