A New Group-Contribution Method for the Estimation of Physical Properties of Hydrocarbons

In the present work, we propose a new group-contribution method to estimate the boiling point, freezing point and the liquid density at 20°C of hydrocarbons. The method was tested with satisfactory accuracy, and when compared with other group-contribution methods, it reveals better results in terms...

Summary:In the present work, we propose a new group-contribution method to estimate the boiling point, freezing point and the liquid density at 20°C of hydrocarbons. The method was tested with satisfactory accuracy, and when compared with other group-contribution methods, it reveals better results in terms of average standard deviations. Dans le présent article, nous proposons une nouvelle méthode de contribution de groupes pour l'estimation de la température d'ébullition, du point de congélation et de la densité liquide à 20 °C des hydrocarbures purs. La méthode a été établie avec une assez bonne précision et, comparée à d'autres méthodes de contributions de groupes, elle a enregistré de meilleurs résultats en termes de déviations standard moyennes.
