FIELD: chemistry.

SUBSTANCE: invention discloses an alternative motor fuel with octane number by the research method of not less than 90 units and a vapour pressure of at least 40 kPa, which includes ethanol, aromatic hydrocarbons C₇-C_10, and raffinate, characterized in that it comprises raffinate of the aromatic hydrocarbon production with a vapour pressure of not less than 35.0 kPa, boiling in the temperature range of 45-120°C, with the following ratio of components, wt %: ethyl alcohol 20-40, aromatic hydrocarbons C₇-C₁₀ 1-20, raffinate to 100. Alternative motor fuel must satisfy the basic requirements for the characteristics of automobile gasolines in accordance with GOST 32513 and TP TC 013/2011.

EFFECT: development of alternative motor fuel with the octane number by the research method of not less than 90 units and the saturated vapour pressure of not less than 40 kPa, low sulfur, a high chemical stability, further improved anti-corrosion properties.
