Abstract:

An investigation of the effects of nitrogen compounds on sediment formation was initiated. Several different nitrogen compounds were studied including 2,5-dimethylpyrrole, indole, carbazole and a number of aromatic and aliphatic amines. The diluent employed was purified n-decane. All of the compounds caused darkening of the fuel although appreciable amounts of sediment were formed only with the pyrrole derivatives. The sediment formation was found to be strongly catalyzed by light and by organic acids. Some phenols retarded the sedimentation. A start was made toward characterizing the sediment obtained from 2,5-dimethylpyrrole. It appeared to be a low molecular weight oligomer of partially ozidized pyrrole units. Author
