A New Method for the Characterization of Solutes and Solvent Phases Using Solvotochromic Parameters.
Abstract
Several hundred new secondary log L16 values, obtained by correlation with published data, are presented in this report. Additionally, there are 35 secondary log L16 values from data obtained experimentally on Apiezon L, by the gas chromatographic method and 26 new log L16 values determined directly on hexadecane. These are all collected in Section 1. Now that we have an extended set of parameters, we have repeated the regressions on the Laffort data set for some 190 solutes, to obtain final equations in terms of the parameters pi2, alpha2, beta2 and Vx or log L16. There still remains the problem that a positive, statistically significant coefficient of beta2 is found for liquid phases that have no acidic property. A start has been made on replacing the delta/pi2 formalism by the dipole moment, and regressions on this basis are set out in Section 2.
