Keywords: gasoline, boiling temperatures of fractions, density, non-empirical quantum mecha-nical calculations, intermolecular complexes, benzene, aromatic hydrocarbons, energy of the interaction

Annotation:

Non-empirical quantum mechanical calculations were carried out. It is shown that the presence of benzene in low and in high boiling gasoline fractions takes place because of formation of intermolecular complexes of benzene with other aromatic hydrocarbons. The energy of the interaction of molecules in these complexes exceeds that of thermal movement, therefore such complexes are stable enough.
