PROCESS FOR UNLEADED AVIATION GASOLINE PREPARATION Russian patent published in 2017 - IPC C10L1/00 C10L1/04 C10L1/16 C10L1/223 

FIELD: chemistry.

SUBSTANCE: invention discloses a method for unleaded aviation gasoline production, which comprises alkylate, isomerate, aromatic hydrocarbons and catalytic reforming monomethylaniline compounding, based on a debutanized 45-135°C alkylate fraction, containing not more than 2 wt % of butanes, which is obtained by rectification from the general alkylbenzene fraction, and toluene and xylene are used as the aromatic hydrocarbons, with the following component ratio, wt %: 45-135°C alkylate fraction - 40.0-80.0; toluene and xylene - 10.0-30.0; isomerizate - 5-35.0; monomethylaniline - 0.5-1.5; wherein the weight ratio of xylene and monomethylaniline ranges from 1:1 to 5:1. Gasoline quality indicators correspond to ASTM D 7547 (Avgas UL 91).

EFFECT: obtaining of aviation gasoline with high stability and with the necessary margin of detonation resistance.
