Abstract
A correlation method based on the group contribution concept was devel oped to calculate normal freezing points by using only the structural information. With this method, normal freezing points have been calcul ated for 1,310 organic compounds, and when compared with experimental data, this method produced an average absolute percent error of 8.2%. No other physical properties are needed in using this predictive metho d. A comparison with the method of Joback is also presented.
