Problems solved by technology

Many octane improving compounds used for improving engine performance and extending fuel supplies, such as tetraethyl lead, aromatic compounds, methylcyclopentadienyl manganese tricarbonyl, methyl tertiary butyl ether (“MTBE”) and other such additives, have fallen into disfavor because of concerns about adverse environmental consequences arising from their use.
If the engine is operated with a gasoline fuel, which has a lower octane number than the minimum requirement for the engine, “knocking” can occur.
Knocking occurs when a gasoline fuel spontaneously and prematurely ignites or detonates in the engine prior to spark plug initiated ignition.
Further accumulation of depos

example 1

[0114] A mixture of 15 gm of oil orange dye, 24.15 gm of polyisobutelene bromide and 100 ml diphenyl ether was refluxed for 8-10 hrs under stirring with elimination of HBr. The reaction monitored by TLC. After completion, reaction mixture was dumped in 200 ml water to remove acidity. Solvent was removed azeotropically and residue is distilled at reduced pressure. The yield of oil orange dye-polyisobutelene-oil orange dye conjugate reaction product was 52%.

example 2

[0115] A mixture of 15 gm of free base of dye (indoine blue), 18.3 gm of Polyisobutelene bromide and 50 ml of diphenyl ether was refluxed for 4 hrs under stirring with elimination of HBr. The reaction monitored by TLC. After completion, the reaction mixture was dumped in water, solvent was removed azeotropically and residue was distilled at reduced pressure. The yield of indoine blue dye-polyisobutelene-indoine blue dye conjugate reaction product was 96%.

example 3

[0116] A mixture of anisic acid (5 gm), 2 ml of concentrated sulphuric acid and 55 ml of absolute ethanol was refluxed at 80° C. for 8 hrs under stirring. The reaction monitored by TLC. After completion, reaction mixture was dumped in cold water and oily layer was separated. The aqueous layer was extracted with dichloromethane. This extracted layer and oily layer were combined and washed with 5% sodium bicarbonate solution to remove unreacted anisic acid. The dichloromethane was removed and residue was distilled at reduced pressure. The yield of ethyl anisate was 86%.

Abstract

Anti-knock gasoline fuel compositions are provided including anti-knock additives and mixtures thereof. The octane quality of fuel for an internal combustion engine improved with the anti-knock additives.

Description

CLAIM OF PRIORITY [0001] This application claims the benefit of filing date of U.S. Provisional Application Ser. Nos. 60 / 562,028 filed on Apr. 14, 2004 and 60 / 643,620 filed on Jan. 13, 2005, which are incorporated by reference in their entirety.FIELD OF INVENTION [0002] The present invention relates to anti-knock gasoline fuel compositions and methods of increasing octane index of the gasoline fuel. The invention also relates to methods of improving anti-knock of gasoline fuel by admixing the above-referenced compositions without significant environmental consequences. BACKGROUND OF INVENTION [0003] Fuels, particularly gasoline grade fuels have undergone many changes over the years in order to improve engine performance and reduce engine emissions. Many octane improving compounds used for improving engine performance and extending fuel supplies, such as tetraethyl lead, aromatic compounds, methylcyclopentadienyl manganese tricarbonyl, methyl tertiary butyl ether (“MTBE”) and other s...
