Development of Abraham model correlations for solvation characteristics of linear alcohols

Fluid Phase Equilibria (Impact Factor: 2.38). 01/2009; 286(2):170-174. DOI:10.1016/j.fluid.2009.09.004

ABSTRACT Data have been compiled from the published literature on the partition coefficients of solutes and vapors into the anhydrous linear alcohols (methanol through 1-heptanol, and 1-decanol) from both water and from the gas phase. The logarithms of the water-to-alcohol partition coefficients (log P) and gas-to-alcohol partition coefficients (log K) were correlated with the Abraham solvation parameter model. The derived correlations described the observed log P and log K values to within average standard deviations of 0.14 and 0.12 log units, respectively. The predictive abilities of the each correlation were assessed by dividing databases into a separate training set and test set.
