Composition of gum in cracked naphtha
The types of oxygen and sulfur compounds in two simulated gasoline gums were determined. The first gum was produced by accelerated aging of naphtha in steel drums at 60/sup 0/C for 12 weeks. The second gum was produced by aging naphtha in steel drums for two years at ambient conditions. The gum was separated from the gasoline and analyzed by several methods. Both gums contained thioether, dialkyl peroxide, and other groups, as well as ester, carbonyl, acid, hydroperoxide, and hydroxyl groups. Most of the sulfur in the gum was present as thioether. The rapidly aged gum had a high alcohol content. Oxygen appeared to be a major factor in gum formation, and disulfides and trisulfides appeared to be active promoters.
