Abraham Solvation Parameter Model: Calculation of L Solute Descriptors for Large C11 to C42 Methylated Alkanes from Measured Gas–Liquid Chromatographic Retention Data

Abraham model L solute descriptors have been determined for 149 additional C11 to C42 monomethylated and polymethylated alkanes based on published Kovat’s retention indices upon gas–liquid chromatographic measurements. The calculated descriptors, in combination with previously correlations, can be used predict a number of very important chemical thermodynamic properties including partition coefficients, molar solubility ratios, HPLC data, infinite dilution activity enthalpies solvation, standard vaporization sublimation at 298 K, vapor pressures, limiting diffusion coefficients. predictive computations are illustrated by estimating both the solvation benzene considered current study.
