Abstract: Modern trademark gasolines are multicomponent mixtures composed of hydrocarbons and other organic and inorganic substances. Primarily involved the composition of motor gasolines includes oxygenates (alcohols and ethers) with a high detonation resistance and improved environmental properties. And, their share in the composition of gasolines increases more and more. Earlier, the share of oxygenates in the composition of gasoline did not exceed 3-5% of vol. but now the share of oxygenates may exceed 50% of vol. First of all, the thing is not about alcohols, ethers and amines. For example, the gasoline of E-85 grade contains at least about 85% of ethanol and the rest is presented by gasoline fractions. However, the effect of oxygenates and amines on the processes of gasoline gumming of different group composition formed from a variety of components (straight-run naphtha, gasoline fractions of “catalytic cracking, reforming, isomerization” secondary processes), containing different amounts of resin forming components is not clear. In this study, we evaluated the resin formation of gasoline fraction mixed compositions containing the alcohols, esters and amines of different molecular weight. These substances are often used as the additives to the commercial gasolines. The evaluation of resin formation was carried out in terms of actual resin content. The resin formation of different nature gasoline mixtures with different contents of actual resins is studied. It is proved that the resin formation mixture of gasolines is of non-additive character. The introduction of oxygenates to gasoline composition of different nature reduces their resin formation. A large positive synergistic effect is exhibited by low molecular weight alcohols and amines as well as esters.
