Abstract
Abraham model solute descriptors are reported for the first time for 62 additional C10 through C13 methyl- and ethyl-branched alkanes. The numerical values were determined using published gas chromatographic retention Kováts retention indices for 157 alkane solutes eluted from a squalane stationary phase column. The 95 alkane solutes that have known descriptor values were used to construct the Abraham model KRI versus L-solute descriptor correlation needed in our calculations. The calculated solute descriptors can be used in conjunction with previously published Abraham model correlations to predict a wide range of important physico-chemical and biological properties. The predictive computations are illustrated by estimating the air-to-polydimethylsiloxane partition coefficient for each of the 157 alkane solutes.
期刊介绍：
Physics and Chemistry of Liquids publishes experimental and theoretical papers, letters and reviews aimed at furthering the understanding of the liquid state. The coverage embraces the whole spectrum of liquids, from simple monatomic liquids and their mixtures, through charged liquids (e.g. ionic melts, liquid metals and their alloys, ions in aqueous solution, and metal-electrolyte systems) to molecular liquids of all kinds. It also covers quantum fluids and superfluids, such as Fermi and non-Fermi liquids, superconductors, Bose-Einstein condensates, correlated electron or spin assemblies.
By publishing papers on physical aspects of the liquid state as well as those with a mainly chemical focus, Physics and Chemistry of Liquids provides a medium for the publication of interdisciplinary papers on liquids serving its broad international readership of physicists and chemists.
