In this research, we employed a new method to calculate vaporization enthalpy of pure hydrocarbons. This equation is a function of the temperature, far from critical point and was tested for simple mixtures and oil fractions. Comparing values with the literature, the equation established have improved results in term of average standard deviation. We also applied the equation to the oil fractions; it required a characterisation of these complex mixtures. Excellent results are obtained, which are comparable or better than those obtained with other models.
Key words: Hydrocarbons, simple mixtures, oil fractions, enthalpy of vaporization, group contribution, intramolecular interactions.
