Reaction Intermediates in Aromatic Fuel Combustion.
Abstract
There is increasing tendency in future fuels to have higher aromatic contents because partly of the change in fuel sources (such as coals and shale oils) and partly of the greater use of aromatic compounds as additives due to their high octane values. The chemistry of the oxidation of aromatic compound at combustion temperatures (T > 1500 K) is very complex and poorly understood. This study is part of a series of experiments being carried out to elucidate the oxidation mechanism of C6H6, the most important benchmark system for the aromatic compounds. The unimolecular decomposition of methylphenyl ether (anisole) was studied in incident shock waves covering the temperature range from 1000 to 1580 K and the pressure range from 0.4 to 0.9 atm. The carbon monoxide formed in the reaction, monitored by resonance absorption using a stabilized cw CO laser, could be satisfactorily accounted for by a four-reaction mechanism: C6H5OCH3 yields C6H50 + CH3; C6H5O yields CO + C5H5; CH3 + C6H5O yields o- and p-CH3C6H4OH; and CH3 + CH3 yields C2H6.
