Abstract
In this article, we present a comprehensive quantitative
structure–property
relationship (QSPR) to estimate the Henry’s law constant (<i>H</i>) of pure compounds in water at ambient conditions. This
relationship is a multilinear equation containing eight chemical-structure-based
parameters. The parameters were selected by the genetic algorithm
multivariate linear regression (GA-MLR) method using more than 3000
molecular descriptors. The squared correlation coefficient of the
model (<i>R</i><sup>2</sup>) over 1954 pure compounds is
equal to 0.983 (logarithmic-based data). Therefore, the model is comprehensive
and accurate enough to be used to predict the Henry’s law constants
of various compounds in water
