Ethyl free aviation gasoline composition

Abstract

The invention relates to the field of oil refining and petrochemicals, in particular to an ethyl-free aviation gasoline composition containing an oxygenate additive that does not pose a threat to the environment. The essence of the invention is that the ethyl-free aviation gasoline composition, which includes isopentane, a reforming gasoline fraction boiling up to 180°C, and monomethylaniline, according to the invention, additionally contains a catalytic cracking gasoline fraction boiling in the temperature range of 85-180°C and an oxygenate additive, in the following ratio of components, in mass %: technical isooctane 25 - 70 isopentane 10 - 25 reforming gasoline fraction boiling up to 180°C 5 - 30 85-180°C catalytic cracking gasoline fraction 3 - 10 monomethylaniline 0.5 -1.0 oxygenate additive 9 - 17 where the oxygenate additive maintains a mixture of simple low molecular weight ethers in the following proportions of components, in mass %: diisopropyl ether 15 - 28 ethyl tert-butyl ether 22 - 39 isopropyl tert-butyl ether 33 - 59 others 1 – 4
