A Structure-Property Study of the Solubility of Aliphatic Alcohols in Water

This report presents the best possible QSPR models for predicting the solubility of aliphatic alcohols in water that can be obtained with non-orthogonalized valence-connectivity basis. The corresponding models with orthogonalized basis, ordered in the usual manner, are also given. However, both models are statistically equivalent. Therefore, we proposed a novel approach to the QSPR modelling, which is based on the consideration of all possible or- thogonalization orderings of the valence-connectivity basis and dominant descriptor analysis. This novel procedure produced models that are better than the empirical models of Amidon et al. and the Kier-Hall models when considering the same source of experimental data
