Analysis of Gasoline Octane Ratings and Composition by Travis Slaysman and Drew Landerman
This research focuses on the extraction and analysis of urushiol from gasoline samples, examining its effects on octane ratings. It discusses methodologies for sample acquisition, dilution, and running experiments utilizing mass spectrometry to compare gasoline qualities. The study highlights the relationship between gasoline formulation, engine knocking potential, and emissions, particularly carbon monoxide. Variations in chromatographic purity were observed between different gasoline brands, indicating the impact of additives on fuel quality. The findings contribute to understanding optimal gasoline formulations for performance and emissions control.

Octane Rating is based on comparison with the burning characteristics of a mixture of n-heptane and 2,2,4-trimethylpentane (isooctane). • Gasoline that isn’t formulated properly can lead to engine knocking and increase the incidence of incomplete combustion, resulting in increased carbon monoxide production. Octane Rating Formulation
Volatile organic sample evaporation • Purity of the reagents we used • Mass Spec Utilization Sources of Error
As the octane rating went up, the alkane concentrations became smaller, as we expected. • Toluene, Benzene and related compounds became more concentrated as octane rating went up. • Cyclohexane was also increasing in concentration as the octane rating went up. • Royal Farms seemed to have cleaner chromatograms than Wawa did, this could be due to possible detergents and other additives put in the gasoline.
