Storage Stability of Gasoline: Fundamentals of Gum Formation, Including a Discussion of Radiotracer Techniques

Description: From Abstract: "The data show that sulfur compounds, nitrogen compounds, polycyclics, and olefins enter into gum-forming reactions. Certain sulfur and nitrogen compounds were found to be most reactive in the gum-forming process. Results of this study indicate that the aromatic constituents of gasolines may contribute substantially and directly to gum formation."
