MANGANESE ABSORBERS MINIMIZING REDUCTION IN OCTANE NUMBER OF AVIATION GASOLINES Russian patent published in 2021 - IPC C10L1/00 C10L1/04 C10L1/16 C10L1/26 C10L1/30 

FIELD: aviation; aviation gasolines.

SUBSTANCE: composition of aviation gasoline contains fuel based on aviation gasoline, manganese, an anti-detonation component, and a component, which is a manganese absorber, wherein the specified component, which is the manganese absorber, contains molecules consisting of a central atom and fragments attached to the central atom, where the central atom is phosphorus; fragments attached to the central atom are electron acceptor fragments selected from a group consisting of electron-deficient atoms and electron-deficient functional groups, wherein an electron acceptor fragment includes a substituted aryl group that is directly attached to the central atom, and a substituent in the aryl group is fluorine.

EFFECT: providing a manganese absorber, when using which clogging of spark plugs and manganese deposition are prevented or reduced, as well as the octane number of aviation gasolines is not reduced.
