Oxygenates are hydrocarbon based molecules containing one or more oxygen atoms, most commonly alcohols and ethers. These compounds were added to gasoline in the 1980's as the phase-out of lead began. The additives enhanced octane ratings of fuel while decreasing exhaust emissions, particularly carbon monoxide. Environmental and health concerns have resulted in these compounds being phased out of common gasoline formulations. However, some groups still have an interest in such fuel additives as they improve volumetric efficiency of an engine and produce more power. The problem lies with a quick and accurate detection method. For example, the Sports Car Club of America prohibits the use of certain additives but the currently used fuel check meter only measures the dielectric constant of the fuel. A second test is qualitative for alcohols. However, certain “illegal” formulations can be mixed to pass the first test. This presentation will show how twelve oxygenates were utilized, resolved from each other, and detected in spiked samples of Sunoco 110 racing fuel on a reasonable and useful time scale. Because of the setting of the potential application, i.e., a race track, a Gowmac gas chromatograph (GC) with a thermal conductivity detector was utilized.
