Calculating the Density of Cycloalkane Using the Group Bond Contribution Method

Based on characteristics and connectivity of the groups in molecules, a new method, the group contribution method, was developed that can be used to calculate the density of cycloalkane from molecular structure. The calculated results show that the calculated density of cycloalkane were in good agreement with the experimental data ,and the mean relative deviation was 0.84% for 223 cycloalkanes.
