HYDROCARBON FUEL ADDITIVE Russian patent published in 2005 - IPC

Abstract RU 2246529 C1

FIELD: petrochemistry.

SUBSTANCE: invention relates to automobile gasoline additives used to reduce loss of fuel on storage. Additive includes 35-60% butanol, 30-55% ethylene oxide/propylene oxide-based polyether having molecular weight 402, and 6-12% fluorine-containing quaternary ammonium chloride of formula [C₈F₁₇CONCHC₃H₆N(C₂H₄OH)(CH₃)₂]Cl. Additive further contains 0.2-2.9% N-perfluorononanoyl-β-aminosulfonic acid sodium salt.

EFFECT: reduced vaporization of hydrocarbon fuel components on storage in tanks, enabled reuse of additive due to prevented deposition of additive on tank walls, in pipelines, and fuel filters of engine systems.
