Abstract
Halogenated aliphatic compounds have many technical uses, but substances within
this group are also ubiquitous environmental pollutants that can affect the
ozone layer and contribute to global warming. The establishment of quantitative
structure-property relationships is of interest not only to fill in gaps in the
available database but also to validate experimental data already acquired. The
three-dimensional structures of 240 compounds were modeled with molecular
mechanics prior to the generation of empirical descriptors. Two bilinear
projection methods, principal component analysis (PCA) and partial-least-squares
regression (PLSR), were used to identify outliers. PLSR was subsequently used to
build a multivariate calibration model by extracting the latent variables that
describe most of the covariation between the molecular structure and the boiling
point. Boiling points were also estimated with an extension of the group
contribution method of Stein and Brown.
