ANTIKNOCK GASOLINE ADDITIVE BASED ON ALKOXY-SUBSTITUTED ANILINES AND FUEL COMPOSITIONS CONTAINING THEREOF Russian patent published in 2007 - IPC C10L1/223 

FIELD: liquid fuel additives.

SUBSTANCE: antiknock gasoline additive contains at least two alkoxy-substituted anilines having general formula: (I) wherein R represents ethoxy or methoxy group in o-, m-, or p-positions. Proposed is also antiknock gasoline additive containing one or mixture of at least two alkoxy-substituted anilines of general formula I and oxygenates. Gasoline-based fuel composition contains at least two alkoxy-substituted anilines of general formula I in amounts between 0.1 and 25% of the weight of gasoline. Described is also gasoline-based fuel composition containing one or mixture of at least two alkoxy-substituted anilines of general formula I and oxygenates used in amounts between 0.1 and 40% of the weight of gasoline. Described is further oxygenates-based fuel composition for internal combustion engines comprising, as additives, alkoxy-substituted anilines of general formula I or their mixture used in amounts between 0.1 and 40% of the weight of the base.

EFFECT: increased octane numbers of gasolines.
