| Abstract | ||
| The study involved calculation of octane numbers (ON) of olifens having different molecular formula, carbon number 5 to 9, and boiling points in the range of (40-186 o C) which are present in the gasoline and determining the factors affecting them. Multiple linear regression analysis method is used for this purpose. The suggested parameters in the experimental section are relied on the geometry and structure of the olifens. The results indicate that the double bond length and charge on both sides of the double bond, and the charge of the carbon attached to the double bond as a substituent showed a great effect on the octane number. This gives us a certain conclusion about the oxidation ability when the charge on the double bond is slightly high to start oxidation and radical formation and finally molecular cleavage and energy evolution to continue the engine work. Other parameters are also effective such as the position of the double bond in central and terminal location. | ||
