The original three test gasolines were separated into hydrocarbon-type fractions by column chromatography on silica gel, then these hydrocarbon-type fractions were further separated into boiling ranges by low-pressure distillation. Three groups of samples were placed in 43.3/sup 0/ C (110/sup 0/ F) storage; the initial three test gasolines in both the unleaded and leaded state, 16 supplemental samples as both the whole fuel and silica gel depolarized fuel, and fractions from the chromatographic separation and distillation of the initial three test samples. It was found that removal of polar compounds decreased the stability of the fuel. The depolarized fuels had much more gum initially than the whole fuels, and after 20 weeks storage at 43.3/sup 0/ C the amount of gum was greatly increased. Rapid aging with X-ray irradiation and UV irradiation was investigated. It was concluded that the effect was similar for both methods; since UV irradiation was simpler, work with X-ray irradiation was discontinued.
