HIGH-OCTANE OXYGEN-CONTAINING COMPONENT TO MOTOR GASOLINE Russian patent published in 2023 - IPC C10L10/10 C10L1/16 C10L1/182 C10L1/185 

FIELD: production of high-octane gasoline.

SUBSTANCE: high-octane oxygen-containing component (OCC) for motor gasolines for internal combustion engines with spark ignition is proposed, which is a mixture of isobutyl alcohol (IBA) and saturated paraffins obtained in the process of sulfuric acid alkylation of olefins (alkylate), characterized in that it additionally contains methyl tert-butyl ether (MTBE) in the following ratio of components: alkylate 50-75 wt.%, MTBE 12.5-25 wt.%, IBA - 12.5-25 wt.%.

EFFECT: increasing the coefficient of distribution of knock resistance (CDKR) by fractions and increasing the specific heat of combustion of motor gasoline.
