The Influence of Magnetic Properties and Electronic Structure of Molecules on Motor Fuel Operating Characteristics by Example of n-Alkanes

The influence of magnetic properties and electronic structure of hydrocarbons on such operational properties of motor petrol as octane numbers, defined by motor and research methods, saturation vapor pressure, flash temperature, is shown by the single-factor analysis of correlations by the example of n-alkanes C1-C10. It is shown, that detonation phenomenon in internal-combustion engine, probably, have a critical state nature. Magnetic properties of hydrocarbons are connected with their electronic structure. First ionization potential, assignable by photoelectron spectroscopy, may be recommended as information parameter for the calculation of petrol operating characteristics. Studying of electronic structure of substances is promoting the creation of products with given physical-chemical properties and operating characteristics.
