The effect of sulfur compounds on the storage stability of fuel oil was investigated. A number of different sulfur compounds, of the type that may be present in oil, were added to fuel oil and the blends were stored in vented brown glass bottles at 37.8/sup 0/C (100/sup 0/F). Samples were withdrawn once a month for determination of insoluble sediment and soluble gum. Thiophenes, aliphatic mercaptans, and aliphatic sulfides had little effect on formation of either insoluble sediment or soluble gum. Primary aliphatic mercaptans appeared to have a small inhibiting effect on sediment formation. Free sulfur, disulfides, and polysulfides all increased sediment formation, and thiophenol greatly increased sediment formation. The effect of added sulfur compounds varied from oil to oil; the increase in sediment formation was generally greater in unstable oils than in stable oils.
